Good Guy Gets Top Job.Pete Brownell is the NRA’s new President. Pete was elected as NRA President by the NRA Board of Directors on May 1, 2017, capping off the 146th NRA Annual Meetings and Exhibits in Atlanta. Pete succeeds Allan D. Cors to become the 64th President of the NRA.
We applaud Pete Brownell’s election as NRA President. Your Editor has met and talked to Pete. He is a smart, hard-working, sincere, and focused individual who genuinely loves the outdoors and the shooting sports. He is “one of the good guys”, a true leader in our industry, who also cares about the average gun owner, and who has a clear vision for the future.
“It’s an honor and privilege to serve the 5 million members of the National Rifle Association of America”, said Brownell. “I’m a proud NRA member from day one who grew up with a passion for guns, our rich hunting heritage, and a passion to strengthen our Second Amendment.”
Brownell, whose entire life has been dedicated to the outdoors and shooting traditions, is the CEO of Brownell’s Inc., his family’s namesake business. Pete became the third Brownell to run the business when he assumed day-to-day operations from his father Frank, 72, who remains chairman of the board. Under their leadership, Brownells grew ten-fold from a “niche-specific supplier” of gunsmithing tools to an international company offering firearms, parts, ammo and accessories to shooters, hunters, gunsmiths and retailers worldwide.
Pete Brownell has already given years of service to the NRA. First elected to the NRA Board of Directors in 2010, Pete has served as chairman of the Membership Committee. Pete “rose in the ranks”, being elected as the NRA’s Second Vice President in 2013, and as First Vice President in 2015.
LaPierre, Powell, and Cox Retain Other NRA Top Leadership Roles
At the May 1st NRA Board of Directors meeting, the Board re-elected Wayne LaPierre as NRA Executive Vice President. Upon his re-election, LaPierre then reappointed Josh Powell as Executive Director of NRA General Operations, and Chris W. Cox as Executive Director of the NRA Institute for Legislative Action.

In Brownells’ GunTech™ Archive of instructional articles and videos, Eric Kiesler has written an informative Guide to Metal Prep for bluing or bake-on resin coatings. Eric’s “how-to” advice will be useful for prepping something as small as a scope ring or as large as a complete barrelled action. Here is a selection from Eric’s article:
Gunsmith’s Guide to Metal Prep for Baking & Bluing
By Eric Kiesler
Prior to bluing or the application of a bake-on coating, a steel surface must be properly prepared. In either case, at a minimum the work piece must be thoroughly and completely degreased. There are many acceptable ways to degrease steel parts, so long as no residue remains the method used is not critical. We typically recommend TCE (#083-060-024) for degreasing prior to the application of Brownells Baking Lacquer (#083-046-801) or Oxpho Blue (#082-024-004). The TCE in the spray can is preferable as it allows you vigorously spray the surface, start at the top of the part and hose it down to the bottom chasing the grease off.
Prior to hot caustic Bluing (#082-005-007) the parts are immersed in a heated detergent bath using Dicro-Clean (#082-005-008) because (like TCE) we know it will have no adverse after effects or residue that could cause problems later on. Once the degreasing is complete, the part could be blued or coated, however, with bake on coatings, adhesion is greatly enhanced if the surface of the parts are roughed up. This can be accomplished by sanding them with a fine abrasive cloths, sand paper, Emory Cloth (#657-110-120) or by abrasive blasting. Abrasive blasting is preferable because it will typically reach areas that sand paper might not.
For the Gun Kote (#083-051-001) brand of bake-on finish, aluminum oxide (#084-206-060) must be used as the abrasive blasting media in your abrasive blaster. For our other bake on coatings (and even Aluma-Hyde) sand or glass beads may be used in the blaster. If you do abrasive blast the part (highly recommended), it should be degreased afterwards because the blasting media may have contaminants in it. You don’t want to coat a highly polished part since shiny metal resists the coating, but a highly polished part could certainly be blued.
Each week, Brownells releases a new product video. This week’s review spotlights Hornady match bullets and factory ammo of interest to PRS and tactical shooters. Hornady’s ELD Match ammunition is now offered in the popular 6.5 Creedmoor and 6mm Creedmoor chamberings, along with .223 Rem, 6.5 Grendel, 260 Rem, .308 Win, .30-06, .300 Win Mag, and .338 Lapua Mag. This ammo is loaded with Hornady’s ELD Match bullets which feature heat-resistant tips. The ELD bullet line offers impressive BCs at prices that are quite a bit more affordable than some other match bullets. For example, a 100-ct box of 130gr 6.5mm ELD Match bullets is $32.46 at Midsouth.
For 6.5 Creedmoor shooters, three bullet weights will be offered in factory-loaded 6.5 Creedmoor ELD Match ammo: 120 grain (SKU: 81491), 140 grain (SKU: 81500), and 147 grain (SKU: 81501). Hornady’s 6mm Creedmoor ELD Match ammo is offered in one weight, 108 grain (SKU: 81391).
The 6.5 Creedmoor and 6mm Creedmoor chamberings are very popular with PRS competitors. These cartridge types offer excellent accuracy, and a good ballistics with moderate recoil. Many factory rifles, such as the impressive new Tikka T3X A1, are offered in the 6.5mm chambering.
This video also features Hornady’s new Black Ammunition designed for gas guns. Offerings include 5.45x39mm, 6.5 Grendel, 6.8 SPC, 300 AAC BLK, 450 Bushmaster, and .308 Win. The 6.5 Grendel ammo attracted our attention. That chambering is inherently accurate and could be used successfully in an XTC match rifle or in the new PRS Gas Gun Series.

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.”

There are many reasons you might want to make a chamber cast. You may have acquired an older rifle and need to verify the chamber dimensions. Or, if you have a new reamer, you may want to check the exact “cut” dimensions against the blueprint specs. A chamber casting is also valuable if you run across a firearm that you believe has a custom barrel on it and you want to find out the dimensions of the chamber. Lastly, you may want to prepare a chamber casting to be used in the making of custom dies. (Most reloading die makers know how to work from Cerrosafe chamber casts.)
Cerrosafe is a metal alloy that has some unique properties which make it ideal for chamber casting. First, it has a relatively low melting point of 158 to 190° Fahrenheit. This makes it easy for the handloader to melt the Cerrosafe in his home shop. Second, it shrinks slightly during cooling which allows it to be extracted from the chamber easily. It then re-expands to the chamber’s original size after about one hour at room temperature. After cooling for about 200 hours, the chamber cast will expand to about .0025″ larger than the actual chamber size.
One of our Forum members has done many Cerrosafe castings and he offers this smart advice:
1. Remove the barrel from the action to make the pour much easier. If you don’t remove the barrel, it can be hard to pour through the action (even with a funnel) and can make a mess if you’re not careful.
2. Pre-heat the barrel for 5-10 minutes in the oven on the very lowest setting (170° F in my oven). (DON’T overdo it!). Allow to cool for a couple minutes so you can pick it up and it is under 120° F. Pre-heating the barrel helps the Cerrosafe stay liquid as you pour the casting. This helps ensure a good, complete fit to the chamber.
How to Use Cerrosafe for Chamber Casting
The basic ingredient of Cerrosafe is bismuth. Bismuth is a heavy, coarse, crystalline metal which expands when it solidifies, up to 3.3% of its volume. When bismuth is alloyed with other metals, such as lead, tin, cadmium and indium, this expansion is modified according to the relative percentages of bismuth and other components present. As a general rule, bismuth alloys of approximately 50% bismuth exhibit little change of volume during solidification. Alloys containing more than this tend to expand during solidification and those containing less tend to shrink during solidification.
What all this means for the gunsmith is that you can make chamber castings using only Cerrosafe and a few, simple hand tools. To make a chamber casting, first clean and degrease the chamber. Use a tight-fitting, cotton patch that’s wrapped around a bore mop or brush to plug the bore just ahead of the throat. I usually leave the cleaning rod attached to the plug until it’s time to remove the plug. Melt the entire bar of Cerrosafe in a heatproof container that you can easily pour the hot Cerrosafe out of. You can use a propane torch or heat over a hot plate or the burner of a stove. Cerrosafe melts easily at 158°-195° F. While the casting metal is still liquid, stir very well, skim off the dross, and pour your chamber. The real trick with Cerrosafe is not to overheat it. If you heat the solid slowly, and keep it within the required temperature range, you shouldn’t get any dross.
Note the time the casting was poured. The casting will take only a very short time to solidify, usually within a minute. Wait 30 minutes and then remove the plug from the bore. Turn the muzzle upward and the casting will fall from the chamber. At 30 minutes after initial solidification, Cerrosafe shrinks slightly, so removal is very easy. Allow the new casting to cool thoroughly then measure the casting exactly one hour from the time it was cast. The casting will give you an exact measurement of the chamber. Cerrosafe casting metal can be used over and over. Remelt the entire amount back together and pour the Cerrosafe into a small mold of the appropriate size. Always melt the entire Cerrosafe ingot to make a chamber casting. For best results, never cut off, or use, just a part of the ingot.

Want to upgrade your AR’s trigger? Shooting USA and Brownells have created a video tutorial that shows how to remove a factory AR trigger and replace it with an upgrade. This video illustrates the procedures to follow and the tools you’ll need. Step-by-step, the video explains how to swap the factory trigger group for a self-contained ‘box style’ drop-in trigger module or a traditional (multi-part) trigger system with enhanced performance.
Many AR-15s come from the factory with a military-type trigger that has a long, gritty, heavy pull. Replacing that trigger is one of the best ways to improve your AR’s performance. You’ll be rewarded with a smoother pull, shorter take-up, and reduced pull weight. You will also have a choice between a single-stage and a dual-stage trigger.
The box-style, self-contained drop-in systems from companies like AR Gold, CMC, Timney, and Wilson Combat are the easiest to install. John Scoutten explains: “These self-contained systems … are very simple to install. In fact, all you do is remove the factory parts, drop in the whole system, replace your pins, and you’re done.” Conventional two-piece trigger groups are offered by DPMS, Geissele, JP Enterprises, and Rock River.
The key points of the video tutorial are also explained on the Shooting USA website with text and still pictures. Before you start your trigger project, review Shooting USA’s AR Trigger Upgrade Page. You’ll find helpful close-up photos on that page.
