Happy Mother’s Day 2014

Nancy Thomkins Sherri Jo GallagherToday we want to wish Happy Mother’s Day to all the moms around the world. All of us must remember that we literally owe our lives and our well-being to our mothers, who brought us into the world. Without the love, support, caring, and nuturing of our mothers, none of us would be here. So to mothers everywhere, we say:

“Thank you. Bless you. May your lives be filled with happiness today and everyday.”

Here is a photo of the one of the greatest moms in the shooting community, Nancy Tompkins, along with two of her little girls (who both turned into pretty good shooters themselves). On Nancy’s right is Michelle Gallagher, a top long-range shooter. On the left is Sherri Jo Gallagher, who was the second woman in history to capture the NRA National High Power Championship at Camp Perry. Who was the first woman ever to accomplish that feat? You guessed it — Nancy Tompkins, Sherri’s mom, was the first-ever female High Power Champion.

Multi-Lens Shooting Eyewear Kit — Safety at a Bargain Price

When folks inquire about shooting glasses, they often ask: “Should I get clear lenses, or high contrast lenses, or dark lenses?” The answer is “Yes”, “Yes”, and “Yes”. Variety is good — this lets you pick the best lens for the conditions and for the discipline you are shooting. In a 3-gun match in the summertime, you may want darker lenses. On a hazy day, when shooting F-Class, you may want a high-contrast lens (yellow or orange). When bench-testing rifles or competing at benchrest matches, under a roof or awning, most of the time we prefer clear lenses. This is especially true if the targets are in the shade.

So, there are good reasons to have a variety of lens types. But does that mean you must carry around a half dozen sets of shooting glasses in your range bag? Not at all. Many eyewear makers offer shooting glasses with interchangeable, snap-in lenses. This allows you to adapt your eyewear to the conditions. And now you can get a handy, multi-lens kit for under twenty bucks.

Pyramex 5-Lens Shooting Eyewear Kit
One of the best deals we’ve found is the Pyramex Ducks Unlimited Shooting Eyewear Kit, available now for just $19.30 at Amazon.com (with free shipping for Prime members). This Kit gives you a comfortable frame with five (5) different anti-fog lenses: Clear, Amber, Sun Block Bronze, Orange, and Infinity Blue. The interchangeable lens design lets you easily switch lenses for different lighting situations. Pyramex is a well-known manufacturer of safety eyewear. The Pyramex Kit meets ANSI Z87.1+ safety standards.

Pyramex shooting eyewear interchangeable lens Amazon

Complete Kit with Five Lenses, Case, Retaining Strap

This versatile Pyramex Kit boast five (5) interchangeable lenses. The polymer frame features adjustable temples, rubber nosepiece, and temple pads. The Pyramex Ducks Unlimited Kit includes neoprene carrying case, neck cord, and microfiber lens cloth bag. All lenses exceeds ANSI Z87.1+ standards and provide 99% UV protection. This is a very good deal. Heck, you could pay $8-$9 just for a Croakies neck retainer.

Verified purchasers of this Pyramex Kit have posted very positive reviews on Amazon.com:

“These glasses were really impressive. At the price I was not expecting anything this nice. I am in the military and my unit gets issued the Oakley M frames which go for around $120 if the government doesn’t give them to you for free and I like these better. They extend in length which one might expect but closer to the frame there is another joint that lets you adjust the angles of the [temple arms] separately.” — Zac

“I was surprised by just how many lenses and accessories come with this very complete package. The lens change out is a bit awkward, but with the sheer variety of lens choice which will cover just about any lighting condition you encounter, it more than makes up for that. Great packaging, I really do think the tilt feature is useful as hearing and eye protection at present isn’t really integrated. I use them for shooting, where cheek weld, eye relief and clarity are all important and these do the job well.” — Richard

Hornady Increases Production of 17 Hornet Ammo

Here’s good news for varmint hunters. Hornady just announced that it is ramping up production of the 17 Hornet: “For those of you who love the 17 Hornet, we are manufacturing ammunition right now and you should see it back in stores soon!” The 17 Hornet is a fun, fast cartridge that is ideal for ground squirrels and other small varmints. It has light recoil similar to a 22 WMR, but with the ability to reach out to 300 yards and beyond. Since the 17 Hornet is a centerfire cartridge with reloadable brass, it can actually be more economical to shoot than the 17 HMR, provided you “roll your own”.

Speed Kills — 3650 FPS
Based on the 22 Hornet cartridge case, the 17 Hornet can drive a 20-grain V-MAX bullet at 3,650 fps. At this velocity, the 17 Hornet can match the trajectory of a 55-grain .223 Remington load, but with much less noise and recoil. Take a look at the chart below. You can see that the 17 Hornet’s trajectory (blue line) is almost an identical match for the larger .223 Rem (red line) all the way out to 400 yards or so. The 17 Hornet is an economical, fun .17 caliber centerfire cartridge with way more “reach” than a 17 HRM or 22 WMR.

17 Hornet — Trajectory Comparison

Hornady 17 Hornet varmint cartridge

  • 3,650 fps muzzle velocity with a 20 grain V-MAX bullet.
  • Same C.O.L. as the 22 Hornet – uses the existing action.
  • Trajectory comparable to a 55 grain 223 Rem, but the felt recoil of a 22 WMR.
  • Lower cost and comparable quality to the 17 Fireball and .223 Remington.

Digital Level + Protractor Tool Has Many Uses

Here’s a cool product that can help you level your front rest and rear bag, level your scope, align your target frame, and perform a myriad of tasks around the house. The Digital Angle Cube (aka Electronic Level and Protractor Gauge) is basically a high-tech level that gives you exact angular read-outs to within 0.2 degrees. That’s a lot more precise than any bubble level.

Numerous Shooting-Related Applications
For you position shooters who like to run angled sights, this tool will help you set the rear sight and front tower to exactly the same angle. For High Power guys with 3-way and 4-way adjustable buttstocks, this digital angle gauge can help you quickly and precisely set buttstock angle and cast-off. Even tactical shooters and long-range hunters can use this device to confirm exact shot angle, with greater precision than a plastic protractor or even an expensive Angle Degree Indicator (ADI). Heck you can even use the thing as an anti-cant device (if you don’t mind the extra weight). We’re sure that our clever readers can find even more uses for a digital angle read-out tool.

The Digital Angle Tool sells on Amazon.com for $29.50. It comes with magnets on the sides so you can attach the tool to any ferrous metal surface for a “hands-free” reading. You can find similar devices in hardware and home improvement stores. One of these square, magnet-equipped electronic protractor/levels is made by INSIZE. The illustration below shows how the INSIZE gauge can be used in the field.

Amazing, High-Tech Shooting Facility in Germany

Müller Schiess Zentrum Ulm

Ulm Germany Shooting RangeAt most American shooting facilities, you’re lucky to have running water and an electrical hook-up. Those Germans, with their penchant for advanced engineering, have created an amazingly high-tech (and even luxurious) indoor shooting facility that is truly state-of-the art. The NRA is proud of its modern indoor range in Fairfax, Virginia, but the NRA range can’t hold a candle to the advanced Müller Schiess Zentrum Ulm (MSZU) facility in Ulm, Germany. This vast complex features an indoor benchrest range with video monitors, a full-sized trap/skeet hall, pistol ranges, and a “running game” hunting simulator that actually displays (in 3D view) the placement of your bullet strike in the moving animal prey. On top of this, the MSZU has a cafe, a restaurant, and a large shopping/retail facility.

Ulm Germany Shooting Range

We still prefer shooting outdoors, but for a country like Germany, where long, cold winters limit the opportunities for outdoor shooting, a deluxe indoor facility like this makes sense. German reader JPeelen adds: “The problem in Germany is not [just] the weather but density of population. Noise problems led to the closure of many outdoor ranges. Ulm is unique because it offers a 300 meter indoor range, not just 100 meters[.]” Overall, you have to hand it to the Germans for “raising the bar” to a whole new level. View the Müller Schiess Zentrum’s amazing facilities in the video below. The editor of The Firearm Blog wrote: “I have seen the future… and it is in Germany. If you don’t do anything else today, just make sure you watch this video.”

Lesters Ammunition — It Usually Works…

At first glance, these handsome illustrations look like vintage advertising sheets from the early 19th Century. But then you’ll smile a little when you read the slogan for “Lesters Ammunition”.

Lesters ammunition art

Potential buyers of “America’s Cheapest Ammunition” are assured that “It Usually Works”. Well, that’s comforting. There is also a British version for “Lesters — The Empire’s Cheapest Ammunition”, illustrating a well-fed lion. These Golden Age Parodies are offered as full-size wall posters or magazine-size framed prints, starting at $95.00 from Blue Loon Fine Arts.

Lesters ammunition art

Cheap Tin Signs sells a 12.5″ x 16″ retro-style tin sign printed with the Lesters Bear-Eats-Hunter scene. This vendor offers other parody-style tin signs that should bring a smile to your hunting and shooting buddies. In addition, Cheap Tin Signs offers dozens of other (non-parody) tin signs, with vintage 30s-style artwork for Colt Revolvers, Winchester Rifles, and Smith & Wesson pistols.

Great Man Cave Gift
Looking for an amusing gift for your best shooting buddy, or a “conversation starter” to hang on the wall of your local shooting facility or club-house? Consider a frameable parody print from Blue Loon Fine Arts or a “retro-style” tin sign from CheapTinSigns.com. Both vendors offer art that harkens back to outdoor hunting illustrations from the 1920s and 1930s. But when you look carefully, you’ll see there’s a twist that will leave art-viewers chuckling.

How Hard is Your Brass? 5.56 and .223 Rem Base Hardness Tests

Lake City vs. Lapua — which brass is harder? And how about Remington vs. Winchester? Is the widely-held belief that Win brass is harder than Rem brass really true? To help settle these burning questions (raised in a Forum thread), Forum member Catshooter recently sampled the base hardness of four brands of .223/5.56 brass. He employed a very impressive tool for the task — a $2,500 Ames Hardness Gauge. Catshooter explained that his Ames Guage “is FAA certified and approved for testing aircraft engine parts — it does NOT get any better than that!”

Catshooter measured four cases picked at random from batches of Lake City (LC) 2008 (5.56x45mm), Lapua .223 Rem Match, Winchester .223 Rem, and Remington R-P .223 Rem.

TEST RESULTS
Using Rockwell hardness standards (.062″x100kg, Rockwell “B”), the brass measured as follows:

LC 2008 = 96

Lapua 223 Match = 86

Winchester 223 = 69

Remington “R-P” = 49

Summary of Test Results
Catshooter writes: “For all you guys that have believed that Winchester cases were tougher than Remington — you are vindicated, they are a lot tougher! However, Lake City and Lapua are ‘the pick of the litter'”. Catshooter notes that both Lake City and Lapua are significantly harder than either Winchester and Remington .223 brass. That’s something that we’ve observed empirically (Lapua and LC stand up better to stout loads), but now we have some hard numbers to back that up. Hats off to Catshooter for settling the hardness debate with his Ames Hardness Gauge.

Lapua Scenar-Ls are Ultra-Consistent — Free Lapua Hat

Lapua’s Scenar-L bullets are extremely consistent in weight and dimensions. In our tests, the 6mm 105gr Scenar-L proved to be as uniform in weight and base-to-ogive length as any factory bullet we’ve ever measured. Scary consistent. Now there is a full line-up of Scenar-L bullets in .224, 6mm, 6.5 mm, 7mm, and .308 calibers. Yes, that’s right, Lapua now makes a 7mm match bullet. In fact, Lapua makes two: a 150-grainer and a big, high-BC, 180-grainer.

All these Scenar-L bullets are carried by Grafs.com. There are good supplies in most calibers, but the 7mm 180s (item LU4PL7401) are nearly sold out, and the 6mm 105-grainers are sold out. More of these popular 6mm and 7mm projectiles should arrive later this summer.

FREE HAT with Lapua Purchase

For a limited time, if you purchase Lapua bullets, brass, or loaded ammo from Grafs.com, you can get a FREE Lapua cap. NOTE: Quantities are limited, and this offer is restricted to one per customer.

Julie Says ‘Take a Moment’ for Gun Safety This Mother’s Day

julie golob child safetyTeam Smith & Wesson shooter Julie Golob has a message for this Mother’s Day (Sunday, May 11th). Julie writes: “While some are using Mother’s Day week to push a gun control agenda, I’d like to encourage moms to ‘Take a Moment’. Talk to your kids about firearms safety. Help them learn what to do around firearms and have an open, honest discussion about guns and gun safety.

I truly believe that, no matter if you are pro-gun or anti-gun, everyone should know and understand the basic rules of firearm safety. It is equally important for parents to have the discussion about guns and what to do if your child finds one. Both the NSSF’s Project ChildSafe and the NRA’s Eddie Eagle GunSafe® Program are excellent. They offer resources for parents, educators, and child care providers to help ensure kids stay safe.

Julie encourages all who read this to share the message. So far, on Facebook, the “Take a Moment” image has been shared 639 times, and seen by 66,112 people. That’s the power of the internet. Julie says: “Thank you all so much for helping me spread the importance of firearms safety.”

Getting Started in F-Class Competion

We first ran this story a year ago. Since then, many readers asked us: “Is there a good article that explains how to get started in F-Class?” Indeed there is… Rod Vigstol provides tips for F-Class rookies, plus a checklist of items to bring to the range.

How Easy it is to Have Fun with Rifles and Equipment You Probably Already Have….
Forum member Rod Vigstol (aka Nodak7mm) has written a great Introduction to F-Class for shooters getting started in this rewarding discipline. Rod’s article, which appears in German Salazar’s Rifleman’s Journal website, covers F-Class basics and addresses concerns that “newbies” may have when trying a new shooting sport. Rod stresses that most guys who own a varmint-hunting or tactical rig likely have nearly all the gear they need to give F-Class competition a try.

Intro to F-Class Shooting

CLICK HERE to read Rod Vigstol’s ‘Getting Started in F-Class’ article on Rifleman’s Journal.com

Rod explains: “If you’re reading this, you have more than just a general interest in the shooting sports and in the awesome rifles that shoot tiny groups at insane distances. You probably even have friends that enjoy shooting as much as you do. The quandary you may find yourself in is your friends haven’t quite jumped into it head-first like you have and they haven’t spent a lot of money and time obtaining the equipment you have to go shoot these matches. But you know what? Your prairie-dog shooting buddy or coyote-hunter friend can attend these matches and shoot alongside with you. He or she more than likely already has the basic equipment needed to shoot a match.” Most varmint shooters already have a suitable, accurate rifle and the following equipment:

• A variable-power scope in the 4.5-14x range or higher.
• A front bipod like the trusty old Harris 9″-13″, or maybe even a basic pedestal front rest.
• A rear sand-bag or similar sand-sock to rest the butt stock.
• A basic shooting mat from Midway or at least a piece of carpet or canvas to lay on.

Intro to F-Class Shooting

Rod also provides a handy checklist of items to bring to the range. These include: Canvas or carpet strip (to set under bipod), Notebook, Kitchen Timer, Cleaning Rod, Camp Chair, Elbow Pads, Shooting Hat, and Open Bolt Indicator (OBI). Along with rifle, bipod (or front rest), rear bag, and ammo, that’s pretty much all you need.

Intro to F-Class Shooting

Rod encourages all shooters to give F-Class a try — even novices. Rod explains: “We have all been rookies, newbies, new kids on the block or whatever. So we all have a good idea of what may be going on in your mind, the questions and concerns you may have. I’m telling you this sport is full of fantastic people who deep down find it far more fulfilling to help a new shooter get started than running a clean target. You just have to take the first step to get involved.”

Radical 6″-Wide Offset Pistol for 1000-yard Benchrest

Forum member Eric has built an innovative specialty pistol for long-range benchrest. The gun is chambered in 6.5-284 and built for IBS 1000-yard shooting. Eric originally built the gun with a 3″-wide fore-end, then decided to go with a 6″-wide offset design since the IBS no longer restricts Light Gun Forearms to three inches. Eric explained: “After building the 3″-wide stock I looked at the IBS 1000-yard benchrest rules and found out that there was not a width limit and rails were allowed for a Light Gun stock. I set out to design a 6″ version. I was thinking it should be offset also to help control torque and track straighter. I had a new 6.5mm, 1:8.5″ twist, 1.250″ HV-contour Krieger barrel. I chambered the barrel for 6.5-284 and bedded the stock.”

6.5-284 1000-yard pistol

6.5-284 1000-yard pistol

Eric feeds his pistol Sierra 142gr MatchKings with a load of 51.0 grains of H4831sc. Estimated muzzle velocity with this load is 2900 fps — respectable speed from the short barrel. The gun tracks remarkably well, with very little torque effect, as you can see in the video below.

After initial testing, Eric added a muzzle brake to the barrel. This tamed the recoil considerably. To learn more about Eric’s long-range 6.5-284 pistol, visit our Shooters Forum and READ this POST. To see more videos of the pistol in action (with muzzle brake), visit Eric’s PhotoBucket Album.

SSG Brandon Green Sets Stunning 500-33X NMC National Record

SSG Brandon Green USAMUUSAMU Service Rifle shooter/instructor SSG Brandon Green set a new national record this past week, shooting a 500-33X in the individual Aggregate, National Match Course (NMC) with metallic sights. Green was near-perfect in the 200-yard Rapids, shooting an amazing 100-9X. Green was shooting a Tubb 2000 bolt-action rifle chambered in 6XC. He set the new record using Norma factory ammo. Yep, this was factory 6XC ammo, right out of the box.

National Record Score Card of SSG Brandon Green
SSG Brandon Green USAMU

SSG Green is the current NRA High Power National Champion and Interservice Rifle Champion. He and the rest of the USAMU rifle team have trained hard for the 2014 season. Yet Brandon joked about his record-setting performance, noting that the record was shot with his “back-up” gun. On his Facebook page, Brandon posted: “500-33X NMC. Not positive, possibly a record [Editor: Yes it was.] Not too bad for a #2 gun.” Not too bad indeed, Brandon. Congratulations on this achievement. This bodes well for Green’s goal to win a second straight National High Power Championship at Camp Perry this summer.

Note: After setting a National Record with 500-33X during the individual match with his Tubb 2000, SSG Green followed with a 498 the following day using a Service Rifle during the team match. Remarkable.

Aussie Sets Southern Hemisphere 1K Record with Borrowed Rifle

We recently wrote about a spectacular 2.6872″ ten-shot group shot at 1000 yards in Montana. Well Australian Peter Varley recently turned in another amazing group at 1000 yards — this time 2.010″ for FIVE shots. And he did it with a borrowed gun! That’s not the smallest 1K group ever shot on the planet*, but it’s still an Australian and (we believe) a Southern Hemisphere record. Varley shot the 2.010″ group with a borrowed 17-lb Light Gun at a Canberra Rifle Club match in March of this year. Congrats to Peter for his outstanding shooting. And “hats off” to fellow Queenslander John McQuire, who loaned Peter the rifle.

Shown below is Peter Varley with his target, plus a close-up. You’ll note that two of the five (5) shots go through a paster. You’ll find pasters all over these targets because the Canberra Club “recycles” these large 1K targets many times.

Peter Varley 1000 Yards Light Gun Record

Peter reports: This was shot at a 1000-yard match on the Canberra Rifle Range on Sunday, March 9, 2014. I traveled 1300 kilometers (807 miles) from Nambour (Sunshine Coast) Queensland to Canberra in the Australian Capital Territory.

I had left my rifle case keys at the motel and resigned myself to target butts duty or a lazy day. A friend, John McQuire from Mackay (Central Queensland Coast) said: “Get my 6.5 x 47 out, clean up, and you’re in the first detail (relay)”. So it was a borrowed gun for the shoot. The match commenced around 9:00 am. Conditions were very good — winds were very light with no mirage to speak of. Everything fell into place.”

Gun Specifications: Lawton 7500 action with Jewell trigger, PacNor barrel chambered for 6.5×47 Lapua, home-made custom stock, March 10-60x scope

6.5x47L Load: Lapua 123gr Scenars, with CCI 450 primers and Varget (ADI 2208) powder.

Are You Spinning Your Bullets Fast Enough? Twist Rate Calculator Predicts Gyroscopic Stability

Berger twist rate calculatorBerger Twist-Rate Stability Calculator
On the Berger Bullets website you’ll find a handy Twist-Rate Stability Calculator that predicts your gyroscopic stability factor (SG) based on mulitiple variables: velocity, bullet length, bullet weight, barrel twist rate, ambient temperature, and altitude. This very cool tool tells you if your chosen bullet will really stabilize in your barrel.

LIVE DEMO BELOW — Just enter values in the data boxes and click “Calculate SG”.

How to Use Berger’s Twist Rate Calculator
Using the Twist Rate Calculater is simple. Just enter the bullet DIAMETER (e.g. .264), bullet WEIGHT (in grains), and bullet overall LENGTH (in inches). On its website, Berger conveniently provides this info for all its bullet types. For other brands, we suggest you weigh three examples of your chosen bullet, and also measure the length on three samples. Then use the average weight and length of the three. To calculate bullet stability, simply enter your bullet data (along with observed Muzzle Velocity, outside Temperature, and Altitude) and click “Calculate SG”. Try different twist rate numbers (and recalculate) until you get an SG value of 1.4 (or higher).

Gyroscopic Stability (SG) and Twist Rate
Berger’s Twist Rate Calculator provides a predicted stability value called “SG” (for “Gyroscopic Stability”). This indicates the Gyroscopic Stability applied to the bullet by spin. This number is derived from the basic equation: SG = (rigidity of the spinning mass)/(overturning aerodynamic torque).

Berger twist rate calculatorIf you have an SG under 1.0, your bullet is predicted not to stabilize. If you have between 1.0 and 1.1 SG, your bullet may or may not stabilize. If you have an SG greater than 1.1, your bullet should stabilize under optimal conditions, but stabilization might not be adequate when temperature, altitude, or other variables are less-than-optimal. That’s why Berger normally recommends at least 1.5 SG to get out of the “Marginal Stability” zone.

In his book Applied Ballistics For Long-Range Shooting, Bryan Litz (Berger Ballistician) recommends at least a 1.4 SG rating when selecting a barrel twist for a particular bullet. This gives you a safety margin for shooting under various conditions, such as higher or lower altitudes or temperatures. Try changing the altitude and temperature in the calculator and you will see that the SG can increase or decrease when these environmental factors change. Under optimal circumstances you should aim for a 1.4, that way if you change circumstances you are still over 1.1.
