Saturday at the Movies: Great Tech Advice from Keith Glasscock

Keith Glasscock winning wind youtube channel f-Class f-Open ES SD loading

Keith Glasscock is one of America’s greatest F-Class shooters, as well as a highly respected wind coach. A High Master, Keith finished second overall at the 2021 NRA F-Class Long Range Championship in F-Open division. He also finished second at the 2020 Nationals, tied with F-Open winner Pat Scully on points, but with fewer Xs. And he took second also at the 2019 Nationals. His consistency is unrivaled, which means he definitely knows the secrets of long range wind calling and loading ultra-accurate ammo.

Keith has a popular YouTube Channel with new content every week. On Keith’s Winning in the Wind channel, Keith offers 60+ informative videos on a wide range of topics including wind reading, reloading, component selection, load development, and training. For today’s Video Showcase, we offer four of our favorite Keith Glasscock videos. Each video has important points that can benefit any competitive rifle shooter, whether you shoot in local 100-yard fun matches or compete at the National Level in F-Class, LR Benchrest, Palma, or High Power.

How to Prepare for a Match

In this informative video, Keith explains how to prepare for a major medium- or long-range rifle competition, with a particular focus on F-Class. Keith explains how to prepare for weather conditions and “get the lay of the land” before the match. Even the day of the match, your can look and learn. As one viewer noted: “I’ve noticed some guys playing on their phones during matches. This is an important time to get in sync with wind patterns and fine tune your wind strategy.”

How to Find (and Fine-Tune) Seating Depth

This is Keith’s most popular video. Keith definitely knows how to maximize accuracy by finding the optimal seating depth for each particular barrel. He is achieving groups in the high Ones for three shots. That would be good for a short-range benchrest cartridge, but Keith is achieving that with a .284 Winchester which has much more recoil. If you shoot F-TR or F-Open or even PRS, you should watch this video.

How to Lower your ES/SD and Reduce Vertical at Long Range

This is Keith’s first video in a series on how to improve long range groups, precision, and accuracy by reducing velocity Extreme Spread (ES) and Standard Deviation (SD). To achieve the lowest ES you need to look at multiple processes, including precision powder weighing, careful seating, brass annealing, and primer selection. Another factor is bullet selection. Not all bullets of the same nominal caliber and weight class have exactly the same bullet diameter or shape. Sometimes you can get better accuracy AND lower ES by trying a different brand of bullet. We have found bullet diameters, of the same stated caliber, can vary by up to .0008″ (eight ten-thousandths). Some barrels like the fatter bullets, while other barrels may favor the skinny bullets.

How to Find Bullet-to-Rifling Touch Point

Before you even start to load for a new rifle you need to know the point at which the bullet in a loaded round will first touch the rifling. (This will be a base to ogive measurement on your round). Beyond that point you are “in the lands”. If you load shorter than that base-to-ogive length you are “jumping” your bullets. Some cartridge/bullet combos typically shoot best in the lands, while with other bullets and cartridges, jumping is the way to go. Additionally, with some disciplines it is wise to jump your bullets since you may have to unload a chambered round while on the firing line. In this video Keith shows a number of methods to determine “length to lands” with repeatable precision.

Field Test and Review of SEB Mini-X Coaxial Front Rest

While gear reviews are not the primary focus of Keith’s YouTube Channel, Keith does talk about products he likes and uses. In this video. Keith reviews the SEB Mini-X, the newest coaxial tripod rest from SEB Rests. The Mini-X offers fast, precise windage and elevation adjustment with the joystick control. The unit is much easier to pack and transport than a large, heavy front rest such as a SEB NEO or Farley. The latest Mini-X also has upgraded foot controls that make it easier to level the rest on uneven ground. For more info, see our SEB Mini-X Report.

.300 Blackout Round in .223 Rem AR Upper — Instant Disaster

Photos and Facebook post by Tactical Rifle Shooters

Yet another .300 Blackout disaster. Unfortunately, that .300 Blackout cartridge can fit in a .223 Rem chamber. Shooting a .308-caliber bullet in .223 bore is a recipe for disaster.

.300 AAC Blackout 300 BLK kaboom accident blowup cartridge failure barrel .223 Rem 5.56

.300 AAC Blackout 300 BLK kaboom accident blowup cartridge failure barrel .223 Rem 5.56The .300 AAC Blackout aka “300 BLK”, is a compact 30-caliber cartridge designed to work in AR-15 rifles. It has a shorter cartridge case to accommodate the bigger 30-caliber bullet while still fitting in a standard AR-15 magazine. Unfortunately, that’s the danger. A careless shooter can toss a .300 Blackout cartridge in with .223 Rem rounds without noting. And because the case-head size is the same as the .223 Rem (5.56×45) the rifle’s bolt assembly will happily chamber and fire the .300 BLK round. Problem is, that forces a .308 diameter bullet down an undersized .223-caliber bore. Not good!

This images were provided by Tactical Rifle Shooters on Facebook. The message was clear: “Don’t try to run 300 Blackout in your .223/5.56mm. It won’t end well. The problem is identical rifles and identical magazines but different calibers.”

Image from Accurate Shooter Forum. Cutaway shows the jammed .30-Cal bullet:

For those who MUST have a .300 Blackout, here are some things you can do:

1. Use different colored magazines for .300 Blackout vs. .223 Rem.
2. Fit all your uppers with caliber-labeled ejection port covers.
3. Mark .223 Rem upper handguards with the caliber in bright paint.
4. Mark all .300 BLK Rounds with heavy black marker.

Comments by Folks Who Viewed these .300 Blackout Disaster Photos:

“The .300 Blackout is simply a badly-designed round. A properly-designed round would have had a feature in the shape that would have prevented cross loading in the first place.” — D. Santiago

“I almost made that mistake… I had a magazine of 300 BLK inserted in my .223/5.56 all night. Fortunately, I never pulled the trigger. Once I realized the mistake, I almost got ill. [After that incident] I no longer own a 300 BLK.” — B. Welch

“Happened to me hog hunting from a helo. Gun exploded in my face.” — B. Hood

“Fire-forming projectiles [is] so wrong in centerfire!” — M. Stres

“Had some dude come into the store the other day wanting .300 Blackout ammo to shoot in his 5.56 AR. It took 15 minutes of explaining for him to understand you got to have a .300 Blackout Upper!” — R. Williams

Rule Out “Driver Error” — Test Accuracy with Multiple Shooters

shooting accuracy test savage driver error multiple

When a rifle isn’t shooting up to it’s potential, we need to ask: “Is it the gun or the shooter?” Having multiple shooters test the same rifle in the same conditions with the same load can be very revealing…

When developing a load for a new rifle, one can easily get consumed by all the potential variables — charge weight, seating depth, neck tension, primer options, neck lube, and so on. When you’re fully focused on loading variables, and the results on the target are disappointing, you may quickly assume you need to change your load. But we learned that sometimes the load is just fine — the problem is the trigger puller, or the set-up on the bench.

Here’s an example. A while back we tested two new Savage F-Class rifles, both chambered in 6mmBR. Initial results were promising, but not great — one gun’s owner was getting round groups with shots distributed at 10 o’clock, 2 o’clock, 5 o’clock, 8 o’clock, and none were touching. We could have concluded that the load was no good. But then another shooter sat down behind the rifle and put the next two shots, identical load, through the same hole. Shooter #2 eventually produced a 6-shot group that was a vertical line, with 2 shots in each hole but at three different points of impact. OK, now we can conclude the load needs to be tuned to get rid of the vertical. Right? Wrong. Shooter #3 sat down behind the gun and produced a group that strung horizontally but had almost no vertical.

Hmmm… what gives?

shooting accuracy test savage driver error multiple>

Shooting Styles Created Vertical or Horizontal Dispersion
What was the problem? Well, each of the three shooters had a different way of holding the gun and adjusting the rear bag. Shooter #1, the gun’s owner, used a wrap-around hold with hand and cheek pressure, and he was squeezing the bag. All that contact was moving the shot up, down, left and right. The wrap-around hold produced erratic results.

Shooter #2 was using no cheek pressure, and very slight thumb pressure behind the tang, but he was experimenting with different amounts of bag “squeeze”. His hold eliminated the side push, but variances in squeeze technique and down pressure caused the vertical string. When he kept things constant, the gun put successive shots through the same hole.

Shooter #3 was using heavy cheek pressure. This settled the gun down vertically, but it also side-loaded the rifle. The result was almost no vertical, but this shooting style produced too much horizontal.

A “Second Opinion” Is Always Useful
Conclusion? Before you spend all day fiddling with a load, you might want to adjust your shooting style and see if that affects the group size and shape on the target. Additionally, it is nearly always useful to have another experienced shooter try your rifle. In our test session, each time we changed “drivers”, the way the shots grouped on the target changed significantly. We went from a big round group, to vertical string, to horizontal string.

Interestingly, all three shooters were able to diagnose problems in their shooting styles, and then refine their gun-handling. As a result, in a second session, we all shot that gun better, and the average group size dropped from 0.5-0.6 inches into the threes — with NO changes to the load.

That’s right, we cut group size in half, and we didn’t alter the load one bit. Switching shooters demonstrated that the load was good and the gun was good. The skill of the trigger-puller(s) proved to be the limiting factor in terms of group size.

Air Travel with Firearms — Smart Advice by Stan Pate

tsa luggage rifle case Stan Pate Airline Travel

Savage Arms offers a series of Shooting Tips in the Savage Blog. Here is a helpful article from Team Savage Shooter Stan Pate. This covers how to ship your rifle safely, and then re-establish zero properly when the gun is reassembled after transport.

Traveling with Firearms — Important Advice

Traveling with firearms can be stressful. You must comply with multiple regulations and then trust your expensive guns to airline baggage handlers. And after arrival you’ll need to put your rifles back together and confirm the zeros. This article offers helpful travel advice from Team Savage shooter Stan Pate. Pate has traveled the globe competing with match rifles. Here he shares his tips for making trips easier on you and your firearms.

Easier Air Travel With Firearms
TSA isn’t nearly as careful with your rifles as you are. Proper storage before sending your firearm up a conveyer belt and into the belly of a plane is critical. Stan Pate spends lots of time each year traveling the skies and has devised a system for keeping his rifle safe when going to and from.

“Never travel with your firearm completely assembled,” Pate cautions. “A fully assembled firearm is much heavier than one that has been broken-down and stored. More weight creates more in-the-case movement, which can result in damage. I learned this the hard way years ago. My rifle was actually broken in half when traveling to an international competition. Record your torque settings, use those settings during reassembly and your return to zero should be no problem.”

“Be sure to check on current TSA rules and regulations before travel to be aware of any changes that may effect how you pack your rifles,” says Pate.

Rifle Reassembly and Resetting Zero
The quicker you can reestablish your zero, the quicker you can relax and stop worrying about if your rounds are going to hit their mark during competition. Pate, over the years, has developed a system for rifle reassembly and getting back to zero as quickly as possible. While his torque settings may not be the same as yours, the process can still be used.

“The barreled-action goes back on the stock, and then I tighten all three receiver screws finger tight,” says Pate. “Next, I tighten the front two receiver screws down to 35-inch pounds. The rear receiver screws on this particular rifle likes 15-inch pounds. [Note: Proper torque settings will vary with your action and stock type. Most actions have TWO screws, not three.] Scope attachment comes next, and I follow manufacturer settings when tightening it down. All that’s left to do now is go zero your rifle.”

What, Exactly is Minute of Angle? Videos Explain MOA

one minute of angle

This popular video, viewed nearly 1.9 million times on YouTube, provides a clear explanation of Minute of Angle (MOA) and how that angular measurement is used. Among novice shooters, there is much confusion over this term. In this NSSF Video, Ryan Cleckner, a former Sniper Instructor for the 1st Ranger Battalion, defines the term, “Minute of Angle” (MOA) and explains how you can adjust for windage and elevation using 1/4 or 1/8 MOA clicks on your scope. This allows you to sight-in precisely and compensate for bullet drop at various distances.

For starters, Ryan explains that, when talking about angular degrees, a “minute” is simply 1/60th. So a “Minute of Angle” is simply 1/60th of one degree of a central angle, measured either up and down (for elevation) or side to side (for windage). At 100 yards, 1 MOA equals 1.047″ on the target. This is often rounded to one inch for simplicity. Say, for example, you click up 1 MOA. That is roughly 1 inch at 100 yards, or roughly 4 inches at 400 yards, since the target area measured by 1 MOA increases in linear fashion with the distance.

More Minute of Angle (MOA) Explanatory Videos

This Gunwerks video explains that Minute of Angle subtends approximately 1″ for each 100 yards (well, 1.047″ to be exact). That means a Minute of Angle increases in actual measured size the greater the distance of the target from the shooter.

This lengthy (24-minute) video defines Minute of Angle, and uses multiple diagrams to illustrate how MOA angular measurements works. The video also how MOA-based click values translate to point-of-impact changes at various distances.

Reloading Bench — How to Optimize Case Neck Tension

Case Loading Neck Tension Sierra Bullets Paul Box

by Sierra Bullets Ballistic Technician Paul Box
One thing that plays a major role in building an accuracy load is neck tension [one of the factors that controls the “grip” on a bullet]. I think a lot of reloaders pretty much take this for granted and don’t give that enough thought.

So, how much neck tension is enough?

Through the years and shooting both a wide variety of calibers and burn rates of powder, I’ve had the best accuracy overall with .002″ of neck tension. Naturally you will run into a rifle now and then that will do its best with something different like .001″ or even .003″, but .002″ has worked very well for me. So how do we control the neck tension? Let’s take a look at that.

First of all, if you’re running a standard sizing die with an expander ball, just pull your decapping rod assembly out of your die and measure the expander ball. What I prefer [for starters] is to have an expander ball that is .003″ smaller than bullet diameter. So for example in a .224 caliber, run an expander ball of .221″. If you want to take the expander ball down in diameter, just chuck up your decapping rod assembly in a drill and turn it down with some emery cloth. When you have the diameter you need, polish it with three ought or four ought steel wool. This will give it a mirror finish and less drag coming through your case neck after sizing.

Tips for Dies With Interchangeable Neck Bushings
If you’re using a bushing die, I measure across the neck of eight or ten loaded rounds, then take an average on these and go .003″ under that measurement. There are other methods to determine bushing size, but this system has worked well for me.

Proper Annealing Can Deliver More Uniform Neck Tension
Another thing I want to mention is annealing. When brass is the correct softness, it will take a “set” coming out of the sizing die far better than brass that has become too hard. When brass has been work hardened to a point, it will be more springy when it comes out of a sizing die and neck tension will vary. Have you ever noticed how some bullets seated harder than others? That is why.

Paying closer attention to neck tension will give you both better accuracy and more consistent groups.

Sunday Gunday: 20 PPC Pistol — Great for Varmint Adventures

varmint 20 ppc rampro pistol John Seibel
varmint 20 ppc rampro pistol John Seibel

This week’s featured firearm belongs to John “SnakeEye” Seibel, founder of the VarmintsForFun website. In recent years, John has become a “true believer” in the little 20-Caliber cartridges. He says this light-recoiling 20 PPC, Rampro-actioned pistol is perfect for a quick shot on a critter, taken from the front seat of his truck. John tells us: “A long-range pistol is an ideal truck gun in my opinion. It stows in a small area and doesn’t take up the room a rifle does. Just keep ear protection near by at all times! I’ve taken varmints as far as 400+ yards with this 20 PPC pistol, so why would you need a rifle?”

Perspectives on Pistols for the Varmint Hunter

by John Seibel
I decided to try my hand at shooting varmints with a pistol one day when I grew tired of wrestling a rifle around in the truck for a quick shot. Many times when traveling around on the farm you’ll spy a groundhog or fox that usually isn’t more than 200 yards away. A single-shot pistol like the Thompson Contender could fit the bill. With its compact length, around 20 inches, a long-barrel pistol can lay on the truck’s passenger seat for easy access. I usually keep my two leather brick-style sandbags laying beside the console and seat. I have a box made from hard rubber that I lay across the top of the door. I then lay the two bags on top. This makes a nice platform to rest the pistol’s forearm. I like to use a forearm that is at least two inches wide. That lets the gun lay steady—almost like you are shooting from a bench rest. For the shooting hand, I prefer a pistol grip with finger grooves and a slight overhang or flare for the web of your hand.

As for optics, I tried long-eye-relief pistol scopes but they lacked the magnification you need for long-range target shooting or varminting. Those pistol scopes have really long eye-relief because they are designed to work with the pistol held at arm’s length. When shooting at the bench or from a truck that’s not what you want. By the time you find the target and get your eye in the exact location, the varmint has moved on or died of old age! After much fiddling around with pistol-type scopes, I finally decided to use rifle scopes on my long-range pistols. The minimum I use is a 4.5-14×40. Eye relief on a Leupold 4.5-14x40mm is about 3.5 inches at 4.5 power. Field of view is better with rifle scopes too and it’s easier to acquire your target. For this type of shooting a light-recoiling caliber is essential or you will have scope-eye bad! I currently have three long-range pistols and use them to shoot 17M4, 20 PPC, 22 BR, and .223 Rem. The featured gun may be the most accurate of my pistols, and your editor thinks it’s the most handsome of the three.

The Rampro Pistol Project — Working with John Illum
A couple of years ago I called John Illum of Rampro about building the ultimate long-range pistol. It just so happens that John was a big time long-range pistol shooter. I told him that I wanted a gun that didn’t recoil badly and wouldn’t torque when fired. As I am a quadriplegic, with no grip in my hands, the gun had to handle well under recoil so I didn’t drop it. Recoil had to be straight back–no twisting.

Well Illum listened to me and came up with a gun that performs just the way I wanted. Illum suggested a rear grip stock of his own design. It has a 2.25″ wide forearm and a rear grip with a slight palm swell that fits your hand perfectly. Another nice feature is the finger grips. It has an extended overhang or “beavertail” that fits comfortably in the web of your hand. Of course it had to be walnut! I chose Rampro’s STP small action with a PPC bolt. His bolt uses a Sako-type extractor. The action is a single-shot. Being right-handed, I chose a right bolt, left port configuration. This works really well in a pistol. You can load with your left hand and see the round laying in the action–that’s what you want in a pistol without a safety.

Gun Specifications
John Illum’s Rampro actions are chrome-moly steel. Commonly you’d see them blued, but I had him put a brushed nickel finish on the action and rings. From a few feet away it looks like stainless. The trigger is Illum’s own design set at 8 ounces, and there’s no creep that I can detect. The action has Remington barrel threads and will accept Remington type triggers. One neat thing is that the action was milled with an integral recoil lug (much like the current Surgeon Action). And the bolt is milled all in one piece–no soldered-on handles. My only gripe with this bolt handle is that it could be a tad longer, but it still is manageable for a single-shot. You’ll also note how slick and streamlined the scope rings are. Illum made those as well. His rings mount to the action via two screws from the inside of the ring, a very elegant set-up for sure. (I currently have a 6.5-20x40mm Nikon scope on this gun. If I had to do this project over again the only thing I would change would be installing a 30mm scope because I like ‘em!).

The barrel is a PacNor Super-Match heavy taper with flutes milled by John Illum, who did all the gunsmithing on this pistol. Twist rate is 1 in 12 inches, with an 11° crown, polished to a mirror finish. The barrel was bead-blasted on the exterior to cut glare. I had Illum cut a 20 PPC minimum-spec chamber, with a .237″ neck. That way I don’t have to turn necks on the Lapua Brass (220 Russian necked down to .204). This is a varmint gun–there’s no need for turned necks. [Editor’s Note: Rampro is no longer in business. However, John tells us “I haven’t had any problems with the action so far. If I did, most competent gunsmiths could fix them easily.”]

Handgun Handling Tips
If you want to shoot a long-range pistol but have never have shot this kind of gun before, try to find a mentor — someone with a gun like this who can school you a bit in the correct technique. The first thing you notice is that you have no comb or cheek piece to help align your head and neck. And getting used to the optics takes some practice. Most people fit a pistol-type (long eye-relief) scope, but these can be awkward to use, and somewhat frustrating at first — the field of view is very restricted. Move your head very slightly and you can lose the sight picture completely. You can solve that problem by using a standard rifle scope, but that will put your head very close to the eye-piece — just three to four inches. With that arrangement, if you don’t hold the gun correctly … POW instant scope-eye!

Now once you get the hang of shooting a long-range pistol you will find it can be just as accurate as a rifle. But there is a trick to shooting them. Shooting a long-range pistol is a whole new world — you need to hold it just right. If you don’t let the gun roll back a little (i.e. if you grip too hard) you will get vertical stringing. I hold my hand against the back of the grip to guide the gun but let it almost free recoil. Looking at how compact the pistol is, you might think “Hey, this would make an ideal ‘walking-around’ varminter.” Well, that’s not really the case. For real precision shooting a solid benchrest type set-up is a must. You can attach a bipod to a long-range pistol, but you would need a flat surface. A fence-post top would work pretty well without a bipod if you carry a small light bag. Overall though, this type of pistol works best as a sandbag gun. For a walking-around gun, you’d be happier with a rifle I think.

Load Development and Accuracy
When I built this gun, Hornady had just released the 32gr V-Max (see footnote), a good match for my barrel’s 1:12″ twist. I choose the 20 PPC because of the very good Lapua brass (220 Russian parent case). I figured teaming Lapua brass with the little .204 bullet would offer excellent accuracy combined with very low recoil. My expectations were fulfilled. The brass proved to be excellent and the PacNor loved the little V-Max pills.

I tried quite a few different loads and most powders that I tried worked very well. These included: H322, Benchmark, AA 2460, and Reloader 7. Amazingly, with just 14″ of barrel, all of these powders delivered impressive velocities–ranging from 3914 to 4074 fps. I settled on 48 Harrell’s clicks of Accurate Arms (AA) 2460, which drives the 32gr V-Maxs to 3995 fps.

With AA 2460 the gun will shoot in the low 3s at 100 yards consistently — as long as I steer the gun right, which takes some practice. I think groups in the low 0.3″ range is excellent for a non-benchrest factory bullet. Despite having no buttstock to grab, recoil on my 20 PPC pistol is very minimal — it just rocks back into your hand. The main problem is to keep the scope from smacking you, since I used a rifle scope with short eye-relief. Muzzle flash and noise are tolerable but DO NOT shoot one of these without good ear protection. Your ears are very close to the muzzle.

I also have a 20 PPC rifle built on a BAT action with a Richard’s #008 laminated stock cut down in size. That gun’s 1:9″-twist Lilja barrel lets me shoot the Berger 50gr LTB bullets. In the wind, these perform quite a bit better than the 32s. My two favorite loads for the 50 grainers are: a) 26.0gr VV N135, CCI 450 primers, 3615 fps; and b) 27.3gr Hodgdon Varget, CCI 450s, 3595 fps. The BAT 20 PPC also shoots really well with the 40gr V-Max, pushed by N135 and Fed 205M primers.

Pistol Action Legal Issues
One important thing to remember if you build a pistol is to make sure the receiver came from the factory as a pistol and was titled as a pistol. Rifle actions are illegal to use as a pistol. Yes, that’s a nonsensical law, but it’s still on the books. You can use factory pistol actions such as the XP 100.

If you want a new custom action such as a BAT (my favorite), you can order it as a pistol action and when you get it, register it as a pistol. Note, in some states there may be additional fees, waiting periods, or restrictions for pistol actions (as opposed to rifle actions). Check your local laws before ordering the action.

Future Trends in Varmint Hunting — Plenty of Twenties

I think these sub-caliber rounds, both 20s and the 17s, are the future of recreational varminting, at least out to medium distances. The Twenties offer low recoil, excellent accuracy, and components keep getting better and better. The bullet-makers are finally making high-quality bullets in appropriate weights. Compared to something like a 22-250, I’ve noticed that my 20 PPC rifle has a lot less noise, a plus when you want to be quiet around other people and varmints.

The flat trajectory is another big advantage in the field. With the 20 PPC, zeroed at 100 yards, I can pretty much hold dead center and get hits out to 300 yards or so without touching the scope to add elevation. [Editor: The same is true with the 20 Practical cartridge, basically a .223 Rem necked down to .20 Caliber. It has proven very accurate and easy to tune.]

The 20-Caliber cartridges we have now, in particular the 20 PPC and 20 BR, are very well-refined. You don’t have to do a lot of tuning or tinkering to have a very accurate, effective varmint-slayer. In fact, if I could dream up a signature “20 VFF” (Varmints For Fun) cartridge it would basically be the 20 PPC. In truth, nearly any of the popular 17- or 20-Caliber cartridges will perform well if you start with top-quality brass. The sub-calibers have less recoil and burn less powder, and there are very good components for most varmint and target-shooting applications. To me it seems that these small calibers work so well because of good components, low recoil, and efficient cartridge designs (particularly in the VarTarg and PPC cases).

WARNING: For your own safety, ALWAYS reduce all starting charges by 10% and work up carefully! Ambient temperature changes, powder lot variations, and differences in barrel friction can result in significantly increased pressures.

Footnote: When first manufactured, the small Hornady 20-Caliber V-Max bullet was actually 33 grains, not 32 grains as sold currently. I still have some of the 33-grainers. I’ve observed no functional difference between the 33s and the current 32-grainers.

Saturday at the Movies: Gun Safes — Features and Installation

Gunsafe gun safe saturday movies video showcase vault security modular

Today’s Saturday Showcase covers gun safes. Every firearms owner should have a secure, quality gun safe with ample capacity. There are numerous choices in gun safes — but we have one key bit of advice — buy BIGGER than you think you need, because your gun collection will likely grow over time. Also you should consider the fire rating of your safe. There are other key factors to consider, such as wall thickness, lock type, shelf and storage layout, and humidity control. We recommend that all Bulletin readers read our detailed, Gun Safe Buyers Guide. This in-depth 9400-word article covers ALL these topics:

Anti-Corrosion
Budget Safes
Bolt Layout
Door Seals
Fire Proofing
Handgun Storage
Hinges
Humidity Control
Installation Tips
Interior Layout
Interior Lighting
Locks–Dial vs. Digital
Modular Safes
Rotary Racks

Technical Features of Gun Safes — What You Need to Know

This is a very sensible, informative video that examines the technical features of gun safes. You’ll learn about the steel “gauge” or thickness, the different types of hinges, lock controls, and fire-proofing options. We think anyone contemplating purchase of a large home safe should watch this video, prepared by a respected safe retailer in Las Vegas.

Assembly of SnapSafe Titan XXL Double Door Modular Safe

In this video Gavin Gear of UltimateReloader.com shows the unpacking and assembly of a large, twin-door SnapSafe modular safe. This video shows how individual panels are assembled one by one, and how the twin doors are attached. Gavin also shows the process of installing the interior insulation panels which provide basic fire protection. Remarkably, this entire XXL modular safe can be put together with simple tools in less than an hour. SEE Full Article HERE.

Features of a Quality Safe under $1000

Even if you already have a safe, this video is well worth watching. The host shows a variety of accessories and upgrades that all gun safe owners should consider. The host explains why you should have a dehumidifier or Golden Rod. He also shows how to install handy interior lights that activate automatically when the door is opened.

The Gun Vault — The Next Step Beyond a Jumbo Gun Safe

If you have a very large gun collection and are building a new custom home, you may want to consider a Gun Vault. This is essentially a large, secure room, with a very heavy door and thick walls. In this interesting video, Atlas builds a large walk-in gun vault using the Gallow Tech Shelving System and a Fort Knox Gun Vault door.

After the Fire — What Actually Happens in a Burned Safe

In this video, the hosts open a “fireproof” gun safe that went through an actual house fire. See what happens when a gun safe that is supposed to be fireproof actually is exposed to a major fire. The results are surprising to say the least. This video shows that you need to do your homework before buying a “fireproof” safe. Understand how the fire rating systems work, and learn how the interior materials and construction make a big different in real world fire protection.

Mechanical Locks vs. Electronic Locks — What You Need to Know

One important decision when buying a gun safe is the choice of locking mechanism. Should you go with a mechanical lock or an electronic lock? There are pros and cons to both dial locks and e-locks, and as long as you get a quality lock, neither is a bad choice. To help you make your decision, This video explains the differences between the two, and reasons why you might choose one over the other.

How to Assemble a Modular Safe with Simple Tools

For gun owners who move frequently, or who may live in an upstairs apartment or condo, a modular safe makes sense. Steelhead Outdoors, based in Minnesota, offers three different safes: Nomad 26, 32, and Nomad 38. The video below shows how to assemble a Steelhead Outdoors Nomad series safe. If you have basic skills, these safes can be assembled easily in 60-90 minutes. Steelhead recommends having two people to do the job. The entire safe ships in four (4) boxes. Wrenches are included with the safe.

This time-lapse video shows the entire process of assembling the safe, start to finish.

Guide to Quick Access Handgun Safes

A quick access safe can keep your pistol secure, but also readily accessible. But not all of these devices are created equal. This video explains the features you need in a small pistol safe. The video also examines the pros and cons of seven different handgun safes. We recommend that you do NOT keep your handgun safe in plain view, such as on a bedside table. There are other locations where you still have quick access, without tempting home intruders.

Wireless Hygrometer Reports Temperature and Humidity Inside Safes

The Hornady Security® Wireless Hygrometer monitors temperature and humidity in real-time, all without opening the gun safe. The wireless hygrometer employs a remote sensor inside your safe, which measures temperature and humidity data. This data is then sent to an external base display. Wireless technology eliminates the need to open the safe and check the storage environment, preventing temperature and humidity spikes from the outside air.

The display features a large touchscreen that shows current high/low data from both the base and remote units in Fahrenheit or Celsius. The hygrometer pairs with Hornady Security’s in-safe dehumidifiers to combat oxidation-causing moisture.

Gun Safe Installation Recommendations

Every safe, when possible, should be anchored in place with heavy-duty fasteners. Ideally, use multiple bolts in the bottom of the safe, anchored to concrete or solid foundation. Choose the appropriate lag bolts or anchors for the material below your safe. If you can’t mount to the floor, bolt the safe to wall studs. You can locate the position of the studs with an inexpensive electronic “Stud Sensor” available at home supply stores.

Check the thickness of your safe floor. If the steel on the bottom of your safe is fairly thin, place a steel backing strip between the bolt heads and the safe bottom. (Large washers will work, but a backing strip is better.) Without such reinforcement, the bolt heads may pull right through thin-gauge steel if the safe is rocked, or levered from the bottom with a pry-bar.

Locate your safe in the corner of a room or in a recess that blocks access to one or more sides of the safe. On many gun safes, the steel on the top, sides, and rear is thinner than on the door. Blocking access to the sides makes it much more difficult to use power tools on the sides, where the safe is most vulnerable. It’s also wise to place the safe in a relatively tight space with limited room to maneuver. Anything that makes the safe harder to move helps deter would-be thieves.

Many people place their safe in a garage or basement. That’s not necessarily a bad idea, but people also tend to store their tools in the same locations. Don’t store your power tools next to the safe. One safe-maker told us how a customer’s safe was defeated using the owners’ own cutting torch which was stored right next to the safe!

Inspect the area around the safe. Avoid locations where there are a lot of wood beams, paint cans, or other combustible material nearby. In the event of a serious house-fire, these items will fuel the flames, increasing the likelihood that items inside your safe will be heat-damaged. Chris Luchini, co-author of Rec.Gun’s Guide to Gun Safes, offers some practical advice: “Get an alarm system. If the burglars hear an alarm go off, they are less likely to stick round to finish the job. Alarms on both the house and the safe area are a good idea.”

Good Resources for Do-It-Yourself AR-Platform Rifle Projects

AR15 Varmint rifle AR gunsmithing robert whitley

AR15 construction guideMany of our readers use AR-type rifles for Service Rifle matches, varmint hunting, 3-Gun competition, or defensive use. AR-platform rifles can be configured in a multitude of ways to suit the application. But if you plan to put together your own purpose-built AR rifle, how do you get started?

For AR Do-It-Yourselfers, we suggest reading the late Glen Zediker’s book, the Competitive AR-15 Builders Guide. Following on Zediker’s The Competitive AR15: Ultimate Technical Guide, the Builders Guide provides step-by-step instructions that will help non-professional “home builders” assemble a competitive match or varmint rifle. This book isn’t for everyone — you need some basic gun assembly experience and an aptitude for tools. But the Competitive AR-15 Builders’ Guide provides a complete list of the tools you’ll need for the job, and Zediker outlines all the procedures to build an AR-15 from start to finish.

One of our Forum members who purchased the AR-15 Builders Guide confirms it is a great resource: “Much like any of the books Mr. Zediker puts out this one is well thought-out and is a no nonsense approach to AR building. I can not stress how helpful this book is from beginner to expert level.”

Along with assembly methods, this book covers parts selection and preparation, not just hammers and pins. Creedmoor Sports explains: “Knowing how to get what you want, and be happy with the result, is truly the focus of this book. Doing it yourself gives you a huge advantage. The build will honestly have been done right, and you’ll know it! Little problems will have been fixed, function and performance enhancements will have been made, and the result is you’ll have a custom-grade rifle without paying custom-builder prices.” Other good resources for AR projects is Gunsmithing the AR: The Bench Manual, and the Building Your AR from Scratch DVD.

Beware Barrel Bore Obstructions — These Can Cause Blow-Ups

Obstructed Barrel Explosion Accident kaboom
Above is a sectioned barrel showing an 80gr Sierra that was fired in a .223 bolt action with a cleaning rod in the bore. Both the bullet and the rod are still in the bore.

A Negligent Shooter Gets Lucky
“Here we have a story so filled with negligent acts that I can only marvel that the shooter survived the experience. The photo and narrative were provided by the gunsmith who took in the repair job, my comments are in italics. It’s worth reading, we can’t get enough safety warnings in our hobby.” — GS Arizona, Rifleman’s Journal

Description of Incident (with Commentary)
The shooter had a stuck case in his .223 chamber. The stuck case was actually a loaded round that didn’t fire. It wouldn’t extract because it was a .222 case that got mixed in with his .223 brass. [He had loaded the wrong brass.] I saw the loaded round with an 80gr bullet in it and a light primer strike. Negligent Act #1: Wrong brass was mixed in with the brass being reloaded.

The shooter removed the stuck case with a 3-piece aluminum rod. Negligent Act #2: Hammering out a loaded round with a cleaning rod. People have been killed doing this as the round can fire and drive the cleaning rod right into you. I remember one such incident about 5 years ago, the shooter was pounding out a stuck round, the cleaning rod went right through him, he didn’t survive.

The shooter didn’t notice only two segments of the cleaning rod came out when he removed it. Negligent Act #3: If you put anything at all down the barrel of a rifle you’d better make darn sure you got it all out before doing anything else!

He then chambered another round and fired it. Negligent act #4: If you’ve had a barrel obstruction of any kind, and if you’ve put something in the barrel, look through the barrel before proceeding! Within the past two years I know of an incident in which a benchrest shooter was killed in exactly this manner. The pressure built up and the rifle bolt came out of the receiver and into his chest.

The shooter is ‘OK’, but did not escape unscathed. He said there was a huge explosion and after regaining his senses found he was bleeding heavily from his forehead. The blood was thick enough that it ran in his eyes and he couldn’t see. In his words “I thought I was going to die”.

He has what looks like a pretty deep cut about an inch long on the side of his head, right in line with his right eye starting where the eye socket turns out to the side of the skull. And no telling what he’s got in the way of brass particles embedded in his forehead.

He was shooting on private property, and was alone when this happened. Negligent Act #5: Don’t shoot alone! Accidents happen, this is just one more example. If we could predict accidents, we wouldn’t have them. Always shoot with at least one other person.

He managed to get the bleeding stopped, or at least under control, packed his car and drove himself home without seeking immediate medical attention. Negligent Act #6: This one could have cost him his life after being lucky enough to survive the incident. There’s no way to know what’s happened just after an incident like this. He should have been at a hospital getting checked for shrapnel in the head.

The rod and slug could not be driven out. Since the barrel had a high round count there was no point in trying to salvage it. Note that the aluminum rod is expanded to a tight fit in the bore for the first couple inches. The base of the bullet is a little over 2″ from the mouth of the chamber.

What we’ve seen here is negligence and an absolute indifference to the established rules of safe reloading and gun handling, from start to finish, capped off with the shooter’s foolish avoidance of medical treatment. This shooter is lucky to be alive, but he’s surely used up all his luck. Don’t assume you’ll be so fortunate.
