There is a new Gundies Award program for gun-centric social media content creators. Modeled after the Oscars or Emmys, the Gundies Awards focus on the world of guns, shooting, and hunting. Nominees include those who write about guns on Facebook, who post photos on Instagram, and who make videos for YouTube. The annual community-voted Gundies awards spotlight notable firearms-centric content creators. You can register on Gundies.com and then vote for your favorite “influencers” and video-makers. The last day to vote is 12/31/2020.
Mixed Bag of Nominees — Some Good, Some Laughable
To be honest, some of the female “influencers” are just narcissistic social media queens who trade on their looks. They get dolled up in revealing outfits and lots of make-up for posed shots with guns. And on the male side there are plenty of tattooed tactical poseurs with almost no technical knowledge. But there ARE some solid nominees, especially in the Best Shooter and Best Gun Reviewer categories. We showcase videos from five Gundies candidates below. NOTE: These are NOT the category winners — the actual winners will be decided by popular voting which closes December 31, 2020 (better vote soon).
There are 15 Gundies Categories:

1. Gundies Nominee — Mrgunsngear
YouTuber of the Year Category
The Mrrgunsngear Channel has nearly 550,000 subscribers and we know why. This YouTube channel offers a combination of gun-centric content and complimentary reviews of outdoor gear (such as generators, lamps, backpacks, body armor). The host is articulate and a pretty good shooter. He also comments on recent gun law developments, such as the ATF Pistol Brace controversy. Here are four videos that showcase the variety of content from this capable Gundies nominee:
2. Gundies Nominee — Dustin Ellermann
Best Shooter Category
Our friend Dustin Ellermann is a past Top Shot TV Show Champion. He is a very capable shooter who also runs a Christian-focused Camp for kids. Dustin produces multiple videos every month for his Top Shot Dustin YouTube Channel. Here we feature Dustin’s review of the the Volquartsen Summit rimfire rifle. This is a straight-pull bolt rifle available in .22 LR, .17 Mach2 and .17 WSM. Dustin reports: “[The Summit] is extremely accurate as well as a perfect suppressor host.”
3. Gundies Nominee — Caleb Savant (Brownells)
Breakout Creator of the Year Category
While many Gundies nominees have very little technical knowledge of firearms, Brownells Firearm Support Technician Caleb Savant is the exception. Caleb’s Brownells videos cover a variety of technical topics — including sight installation, cartridge terminology, dry-firing, gun maintenance, tool selection, and much more. Honestly, you can really learn a lot from Caleb’s videos for Brownells. In this video Caleb Savant shows how to install a pre-fit barrel on a Savage bolt action. Pre-fits come with the chambers pre-cut, and they have a simple barrel nut that makes installation extremely easy.
Pew Pew Tactical (PPT) has a good website with useful content, such as a very thorough Review of Nine Long-Range Scopes. Along with its Blog articles, PPT offers dozens of videos on the PPT YouTube Channel. You’ll find many reviews of ARs, military-style rifles, and pistols. But in addition, PPT offers many good product reviews that are honest about product pros AND cons — that’s pretty rare these days. Here is one of PPT’s most informative videos, a 7-minute guide to cleaning and lubricating AR-platform rifles. This shows important details for the bolt and bolt carrier group.
5. Gundies Nominee — MrBigKid
Best Cross-Over Category
MrBigKid is not a typical gun-centric YouTube creator. That’s because his videos focus on two main topics — GUNS and BBQ. Since both those topics — shooting and eating — appeal to a broad audience, MrBigKid’s YouTube channel is growing quickly. When you get tired of the “bang and clang” of guns shooting steel, you can switch to pro-level barbecue methodology shared by a talented cook. Here are TWO of MrBigKid’s recent videos, one featuring a .50 BMG rifle and the other serving up delicious smoked Beef Ribs. Be honest… which video did you click first?

Sinclair International has created a series of helpful articles on rifle cartridge reloading. Today’s feature lists ten basic steps for precision hand-loading, with links to longer, detailed Sinclair Int’l technical articles providing more complete information. There’s a lot of helpful info here guys, if you click all the links to access the ten “long form” articles.
Tying It All Together: 10 Steps To Precision Handloads
Feature based on article by Roy Hill, Brownells/Sinclair Copywriter
Sinclair Int’l offers a series of detailed articles on hand-loading precision rifle ammunition. The articles are included in Sinclair’s GunTech Articles Archive, but sorting through the index to find each article takes time. To help you access all these articles quickly, here’s a handy summary of ten key topics, with links to longer articles covering each subject in detail.
Part 1: The first step in making high-quality handloads is to carefully choose the best brass for your application. You need to know how to identify the different types of brass and how to choose the best kind for the ammo you want to load. CLICK HERE for Part 1.
Part 2: Even high-quality brass can have burrs around the flash hole that can interfere with the primer flame and cause inconsistent ignition – which can lead to shot groups opening up. Flash hole deburring is a critical step in making sure primers ignite powder consistently. CLICK HERE for Part 2.
Part 3: The next step is to make sure the primer pockets are square and uniform. Like flash hole deburring, primer pocket uniforming may reduce variations in primer ignition by ensuring more consistent primer seating. CLICK HERE for Part 3.
Part 4: Making sure all your cases are precisely the same length is crucial, especially when you use cases that have been fired before. Case trimming is the way to get there. CLICK HERE for Part 4.
Part 5: After trimming, cases still have to be resized. In order for them to work through the resizing die, they have to be lubricated. The case lube method you choose is crucial to making precision handloads. CLICK HERE for Part 5.
Part 6: Now it’s time to choose the dies that will resize your cases. There are several important options to consider in selecting the right sizing dies. CLICK HERE for Part 6.
Part 7: Wait! You’re not quite ready to start sizing yet. There’s yet more to consider before you start cranking cases through the press. Learn more about setting up and adjusting your sizing dies. CLICK HERE for Part 7.
Part 8: Once the cases are completely prepped, it’s time to start putting fresh components back into them. We start off by seating primers. CLICK HERE for Part 8.
Part 9: After the primers are seated, it’s time to drop in the powder. There are several tools that will help you handle powder for precision handloads. CLICK HERE for Part 9.
Part 10: The final step in the process is carefully seating the bullet to just the right depth. And then… you’re ready to try your loads at the range. CLICK HERE for Part 10.

Important Advice about Building Your Own Black Rifle
This video covers basic legal provisions regarding construction of an AR15 from components. The lower is considered the firearm by the ATF — this must ship to an FFL. The Upper can be shipped directly to the consumer, but there are laws regulating barrel length. In addition, some states have laws prohibiting AR-type rifles. You should always check with a local attorney to determine the applicable gun laws in your city, county, and state.

This video from Brownells talks about a the crown of a barrel and how the crown’s condition affects accuracy. As the bullet leaves the barrel of the gun, the shape, alignment and the condition of the crown can affect the accuracy of your shot. A proper crown is essential to ensure that the bullet leaves the barrel correctly and that the propellant gasses behind the bullet are distributed evenly on firing. A square crown without burrs and a smooth transition will normally ensure consistency from shot to shot. By contrast, a damaged crown can cause unpredictable flyers that open your group. That’s why it’s important to have perfect crowns on all your barrels.
The video explains the different types of crowns that can be used. In addition, the video shows how you can chamfer your muzzle in a home shop. If you use a properly-sized pilot, cutting a shallow chamfer is something that most guys with some mechanical skill can handle. Just be sure to use lubricant, flush chips, and don’t rush the job. Cutting the barrel is another matter. At the 1:20 mark the video shows how to use a hack-saw to remove a damaged muzzle section. While this may be fine for an inexpensive rifle that needs a “quick fix”, we do NOT recommend using a hack-saw with a vise for a competition barrel. The reason is that it is too easy for a novice to produce a cut that is not square. We suggest letting a professional gunsmith cut and crown your competition barrels.

Brownells is a well-known retailer of guns, gun parts, tools, accessories, ammo, and pretty much everything gun related. What you may not know is that Brownells has a very active video production department that releases new “how-to” and product information videos every week. These videos offer helpful advice on gun cleaning/maintenance, reloading, as well as selecting/assembling components for various kinds of rifles. And every week Brownells serves up a new products video. There now over 1000 videos on the Brownells YouTube Channel, this really is a remarkable resource.
Here are six of our favorite recent videos from Brownells. AR owners will find some good advice on spare parts, new reloaders can learn how to use the OAL tool, and all gun owners should watch the video on ammunition storage.
Introduction to PRS Competition
In this video, Tom Beckstrand, former Special Forces Sniper Team Leader and Guns & Ammo magazine staffer, looks at the Precision Rifle Series (PRS). Tom covers the types of stages in a typical PRS match using unconventional, real-world shooting rests. He also discusses the equipment you’ll need including bag supports, bipods, tripods, and optics. As most ranges aren’t set up for PRS, Tom offers tips on how to train at your local range.
How to Use Hornady OAL Tool and Hornady Bullet Comparator
Gun Tech Steve Ostrem explains how to properly use Hornady’s Overall Length Gauge to determine length-to-land precisely. The OAL Gauge uses a “Modified Case” that theads onto the tool and holds a bullet. Push on the back of the gauge until you feel the bullet just touch the rifling. (We do this gently at first, tapping the rod a couple time to ensure the bullet is aligned correctly). Once you’ve got the length, then use the tool with a comparator on your calipers to get the lenght-to-lands. NOTE: We recommend taking the measurement 3-4 times in a row to get a reliable number. With a little practice your should be able to get repeatable measurements within .0015″.
New Bog Pod Tripod and Caldwell Electronic Muffs
Brownells staffer Paul Levy showcases the impressive new DeathGrip Tripod from Bog Gear. The DeathGrip’s adjustable jaws clamp firmly to the rifle’s forearm. This is a useful device for both PRS shooters and hunters. The head assembly has 25-deg front/rear tilt and 360-deg swivel. And the jaws’ non-slip, rubberized padding won’t scratch that stock. The legs snap open to three pre-set hard stops, and there’s plenty of length extension. Easily switch between rubber feet and steel spikes without removing a single part from the trippod. This video also features Caldwell’s E-Max™ Pro noise-cancelling electronic muffs. These affordable 23 dB NRR units boast dual microphones and digital volume controls, and two sizes are offered — Youth and Adult.
How to Store Ammunition Safely and Securely
Notably, this is the single most popular Brownells video this year, with 494,000 views since March 2020. Here’s the deal — ammunition WILL keep for a long time if you store it properaly. DO store ammunition in a cool, dry place that doesn’t have wide temperature swings. Temperature cycling will also degrade primers and powder. Put it in airtight ammo cans to keep out the moisture. Tupperware containers will work too. Brownells also recommends putting moisture-absorbing silica packs in your ammo containers. DON’T just keep ammo in factory cardboard factory boxes stacked in the basement, attic, or garage — especially not on the floor! The ammunition boxes will absorb moisture which will degrade primers and powder and corrode the brass cases. Yes, sealed military ammo will usually handle this kind of storage for quite a while, but it’s still not wise.
Must-Have Spare Parts for AR-Platform Rifles
This is one of Brownells most popular recent videos, with 154,000 views in just four months. Two gun technicians answer the question: “What spare parts should I keep on hand for my AR-15?” On the list are: Gas Rings, Buffer Spring, Extractor Spring and Pin. NOTE: You may want to try the one-piece spiral gas ring rather than the standard rings which require alignment. The cotter pin and cam pin can also easily get lost when the Bolt Carrier Group is disassembled for cleaning. On the lower receiver you’ll want spare springs and detents for the pivot/takedown pins. If you’re using lighter-power springs, keep standard-power spares on hand. If your rifle stops working, swap in the factory-spec springs to find out if the problem is the gun or your ammo. Also, if you have upgraded your trigger, always keep the original trigger as a backup.
Cleaning Advice for .22 LR Rimfire Rifles
Gun Techs Steve Ostrem and Caleb Savant debunk some myths about cleaning .22 LR barrels. One myth is that cleaning will harm the accuracy of a .22 LR barrel. Caleb thinks this myth is the result of people cleaning a barrel from the muzzle and damaging the muzzle crown, which CAN diminish accuracy. If it’s done right, cleaning won’t damage the bore. However, you certainly do NOT have to clean your 22 LR’s bore every time you go to the range. But DO clean the action every time you shoot the rifle, especially on a semi-auto. What about shooting a lot of lead bullets? Won’t that lead up the bore? The guys give us the straight skinny on lead fouling, too. When you see your .22 LR rifle’s groups opening up, you may want to consider cleaning.

Fort Scott Munitions produces 9mm Luger ammo with lead-free solid copper bullets. Shown here is specialized subsonic ammo designed to be used with a suppressor. See FortScottMunitions.com.
The 9mm Luger, aka 9x19mm, is the most popular ammunition type for semi-automatic handguns. As such, with panic buying caused by the Coronavirus pandemic, 9mm ammo is becoming harder to find — or the ammo vendors have jacked up their prices. We found most of the bulk 9mm FMJ out of stock. However, you can still find defensive hollowpoint ammo.
Thankfully, many large vendors such as Brownells, Natchez, and MidwayUSA still have 9mm pistol ammo in stock at reasonable prices. If you can’t find what you need from these vendors, you can source many other ammo retailers via AmmoSeek.com. In addition, Sportsman’s Warehouse has limited 9mm ammo for in-store pick-up in some stores (search online for particular store availablity).
Here are three leading sources for 9mm Luger (9x19mm pistol) ammo. Natchez still has bulk, lower cost lead-core FMJ ammo. Elsewhere cheap 9mm FMJ is mostly sold out, but you can still get 20- or 25-round boxes of defensive ammunition. This stuff is expensive for target practice, to be sure, but at least it can be found.
1. MidwayUSA 9mm Ammo in Stock
Midway USA has quite a bit of hollow-point 9mm luger defensive ammo Available. CLICK HERE to see items in stock, or go to the Midway USA home page and search for “9mm Luger Ammunition”.
2. Natchez Shooters Supplies 9mm Ammo in Stock
As of the time of publication, Natchez Shooters Supplies still has large 1000-round boxes of 9mm FMJ ammunition from CCI and Fiocchi. If you want big quanities of target practice ammo — grab these while you can. In addition, Natchez has NovX defensive ammo.
3. Brownells 9mm Ammo in Stock
Brownells still has a limited selection of 9mm Luger ammunition in stock. Most of the cheaper bulk 9mm is sold out, but here are a few of the brands available on April 10, 2020 at time of publication.
Need a 9mm Pistol? Consider the Walther Creed — Great Value
Need a 9mm carry pistol? The Walther Creed offers excellent ergonomics, good accuracy, and well-designed controls at a killer price — $269.99 at CDNN Sports. This gun, designed to be a value-leader, emulates Walther’s more expensive PPQ model (MSRP $649.00) at a much lower price. The Creed’s frame size and shape is the same as the PPQ, but the Creed lacks interchangeable backstraps. Slide and trigger are very similar. The Creed features a snag-free bobbed hammer. Testers have praised the new Creed, saying that, despite the bargain price, it “sacrifices little to nothing in… ergonomics, accuracy, and reliability.”

Scary stuff — AK-74 after firing corrosive ammo and not being cleaned for a week.
Image courtesy ADCOFirearms.com.
No doubt you’ve heard the term “corrosive” used with respect to ammunition. But what exactly is “corrosive ammunition” (and how does it different from non-corrosive ammo)? What is the chemistry that leads to corrosion, and what cleaning procedures should you follow if you shoot corrosive ammunition? Brownells has come up with answers to these and other questions in a helpful TECH TIP video about corrosive ammo.
In this informative video, Brownells gun tech Steve Ostrem explains the primer-related chemistry that makes some ammo corrosive. The video then reviews suggested cleaning procedures you should follow after you have fired corrosive ammo through any firearms.
What Is “Corrosive” Ammunition?
What makes ammo “corrosive”? Generally speaking, primers are the problem. When corrosive ammunition is fired, the ignited primers leave a residue of corrosive salts. Typically these primers contain potassium chlorate, or sodium petrochlorate which, when burned, change into potassium chloride or sodium chloride. Sodium chloride is also known as common table salt.
Potassium chloride and sodium chloride are both very hygroscopic (i.e. they attract water). Because of that, these alkalis are rust generators. When exposed to the hydrogen and oxygen in the air (and moisture) potassium chloride and sodium chloride can form an acid that quickly causes metal rifle parts to rust and pit.
Given a choice, you may wish to avoid corrosive ammo altogether. However, for some types of fire-arms, particularly older military-style rifles, the most affordable ammunition may be corrosive. If you choose to use corrosive ammo, it is important to clean the gun thoroughly after use. After firing, you want to use an element that will neutralize the primer salts. Brownells suggests a water soak (see video above). Alternatively, Windex with ammonia can help neutralize the salts, but that doesn’t finish the job. After the salts have been neutralized and flushed away, basic anti-corrosion protectant (such as Eezox or other gun oil) should be applied to all metal parts.
This video ahows the effects of Corrosive Ammo after one month without cleaning:
To learn more about the proper procedures for cleaning rifles exposed to corrosive ammo, we suggest an article by Paul Markel on Ammoland.com. Markel, host of the popular Student of the Gun TV series, states that: “Windex (with ammonia) is the Corrosive Ammo shooter’s best friend. After you are done shooting your corrosive ammunition for the day, squirt the window cleaner liberally from the chamber down the barrel. Pull the bolt / bolt carrier / op rod if there is one and douse them as well. A couple of old cotton t-shirts will come in handy. A cotton barrel swab is a nice accessory but you can make do with patches. Some folks will rinse all of the ammonia and loosened corrosive salts off with hot water. Others prefer to wipe it all down and let the ammonia evaporate. Either way, once the corrosive salts have been tackled with the window cleaner, it is time for an all-purpose brush (old toothbrush) and some gun oil.” READ Full Article by Paul Markel.

This illustration shows headspace measurement for the popular .308 Winchester cartridge, which headspaces on the shoulder. Image copyright 2015 Ultimate Reloader.
In this Brownells Tech Tip, Brownells gun tech Steve Ostrem explains what headspace is and why it’s one of the most critical measurements for nearly all firearms. Even if you’re an experienced rifle shooter, it’s worth watching this video to refresh your understanding of headspace measurements, and the correct use of “GO” and “NO-GO” gauges.
Headspace Definition
In firearms, headspace is the distance measured from the part of the chamber that stops forward motion of the cartridge (the datum reference) to the face of the bolt. Used as a verb, headspace refers to the interference created between this part of the chamber and the feature of the cartridge that achieves the correct positioning. Different cartridges have their datum lines in different positions in relation to the cartridge. For example, 5.56x45mm NATO ammunition headspaces off the shoulder of the cartridge, whereas .303 British headspaces off the forward rim of the cartridge.
If the headspace is too short, ammunition that is in specification may not chamber correctly. If headspace is too large, the ammunition may not fit as intended or designed and the cartridge case may rupture, possibly damaging the firearm and injuring the shooter. (Source: Wikipedia)
Headspace Gauges
Headspace is measured with a set of two headspace gauges: a “Go” gauge, and a “No-Go” gauge. Headspace gauges resemble the cartridges for the chambers they are designed to headspace, and are typically made of heat-treated tool steel. Both a “Go” and a “No-Go” gauge are required for a gunsmith to headspace a firearm properly. A third gauge, the “Field” gauge, is used (as the name implies) in the field to indicate the absolute maximum safe headspace. This gauge is used because, over time, the bolt and receiver will wear, the bolt and lugs compress, and the receiver may stretch, all causing the headspace to gradually increase from the “factory specs” measured by the “Go” and “No-Go” gauges. A bolt that closes on “No-Go” but not on “Field” is close to being unsafe to fire, and may malfunction on cartridges that are slightly out of spec. (Source: Wikipedia)
To learn more, read Brownell’s longer article Headspace Gauges and How to Use Them. Among other things, this explains the relative lengths of “Go”, “No-Go”, and “Field” gauges. The “Field” is actually the longest: “The GO gauge corresponds to the SAAMI (Sporting Arms & Ammunition Manufacturer’s Institute) minimum chamber length, while the FIELD gauge usually matches the maximum chamber depth, or slightly less. NO-GO gauges are an intermediate length between minimum and maximum, that, technically, is a voluntary dimension. A firearm that closes on a NO-GO gauge and does not close on a FIELD gauge may not give good accuracy and may have very short cartridge case life from the ammunition re-loader’s standpoint.”
