There are two segments on Shooting USA this week that are well worth watching. On Wednesday (May 18, 2016), Shooting USA features a lengthy segment on the Bushnell Brawl tactical match. This is followed by an “Impossible Shoots” episode featuring top USAMU shooter SSG Daniel Horner.
This Wednesday, May 18th, Shooting USA TV features the Bushnell Brawl, a tactical competition that draws top long-range shooters from the military, law enforcement and the civilian shooting communities. The match is held at the famed Rifles Only range in Kingsville, Texas. The Brawl is a one-of-a-kind physical and mental challenge that tests each shooter’s ability to read wind, figure ballistics, and adapt to difficult shooting scenarios. There is even a helicopter stage.
Shooting from a helicopter, shooting off of a wire, and shooting from the physically demanding maze called the Mouse Trap. These are just a few of the unique courses of fire at the Bushnell Brawl, part of the PRS series. Over the course of two days, competitors tackle more than a dozen stages, and this year Bushnell hosted a special one-day event for the new PRS Production Class. This new division should attract new shooters by limiting the cost of equipment — making PRS competition affordable.
New PRS Production Division — Lowering the Cost of Entry
The Production Division is a new PRS classification. Under Production Division rules, the rifle and scope must cost under $3,000, combined. All other accessories, such as bipod, rear bag, and the sling, can be added at the shooter’s own discretion. By lowering the cost of entry, PRS organizers hope to get more shooters involved: “There’s a lot of gear out there that’s not that expensive that you can use to get into this and start to play the game,” says Production Division Match Director Jacob Bynum.
Shooting USA’s Impossible Shots — Threading the Needle
This time, SSG Daniel Horner has combined with the Army Marksmanship Unit Gunsmiths to set up the ultimate Impossible Shot. Horner attempts to send one bullet through two barrels to pop a balloon.
This challenge is definitely demands the ability to “thread the needle”. In other trick shot challenges this week, Randy Oitker switches to a crossbow to set up his Annie Oakley-style, over the shoulder challenge. Julie Golob is your guide to some of the most amazing exhibition shots ever seen.

The 6.5 Guys, a dedicated duo of Pacific NW rifle shooters, have created an interesting series of shooting-related videos on their 6.5 Guys YouTube Channel. In a pair of YouTube videos, The 6.5 Guys set up and demonstrate the Bench-Source cartridge brass annealing machine. The videos offer valuable tips on setting up the machine, attaching and adjusting the torches, and fine tuning the flame and dwell time to achieve best results.
To complement their videos, the 6.5 Guys (aka Ed and Steve) have published an Annealing Tech Talk article on 65guys.com. If you own an annealing machine, or are getting started with cartridge annealing, you should read that article. It covers basic annealing principles, and gives useful tips on temp control, dwell time, and frequency of annealing. After the video, we feature highlights from this article.
Temperature Control
We use 750° Tempilaq applied inside the case neck to indicate that the proper temperature has been achieved. If you turn off the lights, you will notice that the brass just barely starts to turn color. As you go beyond the 750° mark we observed that the case mouth will start to flare orange — you can see this with the lights on. From our research, we understand that this is the result of zinc burning off. We adjust the time on our machine between the point that the Tempilaq turns liquid and the flame starts to turn orange. In other words, if the flame is starting to turn orange reduce the time. We let the cases air cool — we don’t quench them in water.
The case starts to flare orange here, during a set-up test. Dwell time was then reduced slightly.
Flame Orientation
We aim the flame at the neck-shoulder junction. Some folks like to aim it at the neck and others the shoulder. When you see how the two flames meet and spread out vertically, it probably doesn’t make that much of a difference.
Here you can see the flame points aimed at the neck-shoulder junction.
Case Coloration
Cases will turn color after annealing, but the degree of color change is not a reliable indicator. We have noticed that the appearance of cases will vary depending on brass manufacturer, brass lot, light source, and how long ago the case was annealed.
How Often Should You Anneal?
Some shooters anneal every time while others choose a specific interval. We noticed work hardening around five firings that resulted in inconsistency in shoulder setback and neck tension, so we choose to anneal every three firings. Your mileage will vary depending on how hot your loads are and how aggressively you resize.

The Ruger Precision Rifle (RPR) has been a huge sales success. Nearly a year after its introduction, the RPR remains in very high demand. The first production run by Ruger essentially sold out, so it is very hard to find one for sale, in any caliber.
Though it has a big winner on its hands, Ruger has made some upgrades to its popular RPR. An “enhanced” RPR will be offered with a new handguard, bolt shroud, and muzzle brake. Two new models have been added to the RPR line-up, the model 18004 in .308 Win, and the model 18008 in 6.5 Creedmoor. These models, priced at $1599.00 MSRP, feature a new, low-profile handguard, a new aluminum bolt shroud, and a muzzle brake. The new handguard will work better for scopes with large front objectives. The muzzle brake should reduce felt recoil, but we do wonder whether accuracy might suffer. The brakeless, first-generation RPRs exhibited very good accuracy most of the time.
For the time being, the original model RPRs will be offered along with the new enhanced RPRs: “Both the original and enhanced configurations will be available from Ruger for a time, with the initial pattern being phased out as supplies are depleted.” (Source: American Rifleman). But there is a catch. The new models cost $200.00 more than Gen 1 RPRs. Ruger lists a $1599.00 MSRP for the enhanced RPRs versus $1399.00 for Gen 1 models.
To See NEW FEATURES, click the image below, then SCROLL down the page on the Ruger web page that loads. Yes, the VIDEO is there — you just have to scroll down.
According to American Rifleman, the new handguard has multiple benefits: “Still free-floating and KeyMod-compatible, the new design omits the original’s top-mounted Picatinny rail in order to increase scope clearance. Given the larger objective lenses utilized by long-range optics, this enhancement makes a lot of sense. The bottom surface of the new handguard is also contoured with a flatter surface, providing for a more stable foundation for the mounting of bipods than the original model.” Current RPR owners can purchase the new-style 15″ aluminum handguard for $249.95 from ShopRuger.com.
Ruger RPR Hybrid Muzzle Brake
The original, Gen 1 Ruger Precision Rifle had a threaded muzzle covered by a thread cap. The new “enhanced model” features a factory-installed “hybrid” brake fitted to the barrel. This brake combines radial holes in the rear half with large, angled side ports in the front. Ruger claims the brake reduces recoil almost 40% on a 6.5 Creedmoor. This brake can be purchased separately for $99.95 from ShopRuger.com.
Hey it’s the end of the work week, so we thought you guys might enjoy a little display of honest-to-goodness American .50-Cal firepower. Today’s video features the General Dynamics GAU-19/B Gatling, shown in a vehicle mount (Part 1) and helicopter side-mount (Part 2). The HumVee-mounted version of this bad boy delivers 1300 rounds per minute of .50 BMG ammo. The effect is awesome to behold. We wouldn’t want to be on the receiving end of a GAU. The original GAU-19/A had a selectable rate of fire — either 1,000 or 2,000 rounds per minute. The GAU-19/B, introduced in 2012, provides the same firepower in a much lighter platform, weighing 106 pounds (not counting ammo storage systems).
Never had a chance to hunt prairie dogs in the American west? Then check out this video. Dan Eigen (aka “Walleye Dan”), host of the We Love It Outdoors Television series, head to South Dakota for some varmint hunting. Dan teams up with Varmint Hunter Association President Jeff Rheborg to patrol some South Dakota Dogtowns where things get serious. In the video, you’ll see p-dog hits at distances from 70 yards to roughly 450 yards. The hunters were shooting from portable, wood-topped swivel rests, using AR-platform rifles on X-type sandbag rest. (Rifle zeroing session is shown at the 5:30+ mark.)
Multiple cameras were employed so you can see both the shooter’s POV and close-ups of the prairie dogs downrange. Watch the shooters having fun with a prairie dog cut-out and some Tannerite at the 9:00-minute mark. This guys are having a grand old time sending critters to Prairie Dog Heaven — we think you’ll enjoy the video.
Prairie Dog Hunting Starts at 2:00 Time-Mark in Video:
NOTE: This video actually covers three sequences: 1) Three-gun training; 2) Prairie Dog Hunting; and 3) Coyote Hunting. We’ve embedded the video so it plays back the Prairie Dog segment from 2:00 to 15:15. If you wish, you can slide the controls forward or back to watch the other segments.

Geissele Automatics manufactures a line of two-stage triggers favored by top Service Rifle, High Power, and 3-Gun shooters. Geissele now offers a variety of trigger models for both large-pin and small-pin lowers, with pull weights from 1.8 lbs to 6.0 lbs. You select the Geissele trigger with the appropriate first and second stage pull for your discipline (refer to chart below for trigger model specs).
Video Shows Geiselle Trigger Installation in AR15
Our friend Gavin Gear of UltimateReloader.com has crafted a video showing how to install a Geissele National Match Trigger in an AR15. This video covers installation of the trigger assembly, the trigger guard, the safety selector lever assembly, and the pistol grip.
AR15 Trigger Installation Video
Follow-Up Video for AR10 Trigger Install
Gavin recently released a follow-up video which covers the installation of a Geissele Super Dynamic Trigger in an AR10. The procedure is mostly the same as for the AR15, but this video also covers removal of the AR10 factory trigger, so it’s worth watching. You may want to turn the volume down on your computer’s speakers before playback. CLICK HERE for Geissele Trigger Instruction Manual
In this video, Forum member Erik Cortina shows how to create a custom modified case for use with the Hornady Lock-N-Load Overall Length Gauge (formerly the Stoney Point Tool). While Hornady sells modified cases for many standard cartridges, if you shoot a wildcat such as the 6mm Dasher or .284 Shehane, you’ll need to create a custom modified case*. And even if you shoot a standard cartridge such as the .308 Winchester you can get more consistent measurements if you make a custom modified case from a piece of brass fired in your chamber.
The process is straight-forward. Take a piece of brass fired in your chamber and full-length size it (with about .002″ shoulder bump). Then you need to drill out the primer pocket. Erik uses a mini-lathe for the operation, but this general process can be done with a drill press or other tools. Erik shows how to do this with a 0.290″ HSS (High Speed Steel) drill bit on a mini-lathe. After drilling the hole comes the tricky part — you need to tap the case with the precise 5/16″ x 36 threads per inch (tpi) right-hand thread that matches the male thread on the O.A.L. Gauge. This 5/16″ x 36 tpi tap is pretty uncommon, but you can order it from Amazon.com if you can’t source it locally.
If you use a mini-lathe, Erik suggests loosening the tailstock slightly, so it can float while cutting the threads. Erik also says: “Make sure you get the tap on pretty tight — it’s going to want to spin.” Erik turns the case at about 100 rpm when tapping the threads. Once the case and tap are rigged, the actual tapping process (see video at 6:00) takes only a few seconds. While the mini-lathe makes the tapping process go more quickly, the threading can also be done with other systems.
TIP: Don’t just make one modified case, make three. That gives you one for your range kit, one for your home reloading bench, plus a spare (since you WILL eventually lose or misplace one).
Here’s the Stuff You Need
5/16″-36 TPI Threading Tap
The required thread is somewhat uncommon. You need a 5/16″ – 36 tpi Right Hand Thread Tap. If you can’t find it locally, Amazon.com carries the correct tap. Erik notes: “The 5/16-36 tpi tap is not a common size. I think Hornady did this on purpose to make it more difficult for the average guy to make his own modified cases.”
0.290″ Drill Bit
Erik uses an 0.290″ HSS “L” drill bit. (This “L” Letter Gauge code designates a 0.290″ diameter bit). A close metric equivalent would be 7.3 mm (0.286″). Erik says: “A 9/32″ drill will also work but it will be harder to run the tap in since the hole will be .281″ instead of .290″ with the Letter Gauge L bit.”
Tips for Using O.A.L. Gauge with Modified Case
We’ve noticed that many folks have trouble getting reliable, consistent results when they first start using the Hornady O.A.L. Gauge (formerly the Stoney Point Tool). We’ve found this is usually because they don’t seat the modified case properly and because they don’t use a gentle, consistent method of advancing the bullet until it just kisses the lands.
Here is our suggested procedure for use the O.A.L. Gauge. Following this method we can typically make three of four measurements (with the same bullet), all within .001″ to .0015″. (Yes, we always measure multiple times.)
1. Clean your chamber so there is no build-up of carbon, debris, or lube. Pay particular attention to the shoulder area.
2. Screw the modified case on to the O.A.L. Gauge. Make sure it is seated firmly (and doesn’t spin loose). Note, you may have to re-tighten the modified case after insertion in the chamber.
3. Place your selected bullet so that the ogive (max bullet diameter) is behind the case mouth. This prevents the bullet from “snagging” as you insert the tool in the action.
4. Insert the O.A.L. Gauge into your chamber smoothly. Push a little until you feel resistance. IMPORTANT — You need to ensure that the shoulder of the modified case is seated firmly against the front of your chamber. You may have to wiggle and twist the tool slightly. If you do not have the modified case seated all the way in, you will NOT get a valid measurement.
5. Advance the bullet slowly. (NOTE: This is the most important aspect for consistency!). Push the rod of the O.A.L. tool gently towards the chamber. DON’T shove it hard! Easy does it. Stop when you feel resistance.
6. IMPORTANT. After gently pushing on the rod, give the end of the rod a couple forward taps with your finger. If your bullet was slightly skewed, it may have stopped too far back. Adding a couple extra taps will fix that. If the bullet moves after the taps, then again push gently on the rod. NOT too much! You just want to push the bullet until it just “kisses” the lands and then stops. Do NOT jam the bullet into the rifling. If you do that you will never get consistent results from one measurement to the next.

How would you like to “reach out and touch” someone 203 kilometers away (about 110 nautical miles)? Well America’s Navy may soon be able to do exactly that with an amazing new, high-tech weapon system. BAE Systems has developed (and successfully test-fired) an electro-magnetic rail gun that fires a 23-lb projectile at Mach 7 — (about 5300 mph or 7800 fps). This futuristic weapon can send its projectile 110 nautical miles (126 mi / 203 km), five times the range of the big 16″ guns on WWII-era battleships. This railgun has serious “knock-down” power — at Mach 7, that projectile carries a whopping 32 megajoules of energy. BreakingDefense.com says: “23 pounds ain’t heavy. But it sure hurts when it hits you going at seven times the speed of sound.”
Watch Video to See Navy Rail-Gun in Action:
The latest prototype of the railgun developed by defense contractor BAE, in conjunction with the Office of Naval Research, can accelerate a projectile up to Mach 7 within 10 milliseconds. The gun uses no gunpowder to generate propelling force. Compared to an item on a smaller scale, the railgun projectiles resemble crossbow darts, except they deliver such massive Kinetic Energy they don’t need to carry explosive ordnance. The railgun can strike targets 110 nautical miles away.
To prepare a charge, the ship stores electricity in the pulsed power system. Next, an electric pulse is sent to the railgun, creating an electromagnetic force accelerating the projectile. Because of its extreme speed, the projectile eliminates the hazards of storing high explosives in the ship. Each shot costs about $25,000 — but that’s cheap compared to the price of a missile.
“It’s like a flux capacitor,” chief of Naval research Rear Admiral Mathias Winter said in a video posted by Reuters Friday. “You’re sitting here thinking about these next generation and futuristic ideas, and we’ve got scientists who have designed these, and it’s coming to life.”
The Electromagnetic Railgun Innovative Naval Prototype (INP) was initiated in 2005. The goal during Phase I was to produce a proof-of-concept demonstration at 32 mega-joule muzzle energy, develop launcher technology with adequate service life, develop reliable pulsed power technology, and assess component risk reduction for the projectile.
Phase II, which started in 2012, advanced the technology to demonstrate a repeatable-rate fire capability. Thermal-management techniques required for sustained firing rates will be developed for both the launcher system and the pulsed power system. The railgun will begin testing at sea in 2016.
Varminter.com recently released a First Hunt Report on the new Savage A17 rifle. Savage’s new semi-auto .17 HMR has caused quite a stir. Accurate and affordable, the Savage A17 is also the first .17 HMR to feature a delayed blow-back action. We think the A17 may be the most important new rimfire rifle of 2015, so we were pleased to see that Eric Mayer, Editor of Varminter.com, put the new semi-auto Savage through its paces.
Mayer wanted to see how the new Savage would perform, accuracy-wise, and he also wanted to see how the A17 fared in the field. Mayer achieved one-MOA accuracy with the Savage A17 using the latest CCI-brand ammo, and he demonstrated the A17 is wickedly effective on ground squirrels. Below we’ve provided highlights from Varminter.com’s Savage A17 First Hunt Report.
The 2016 Summer Olympic Games will be held in Rio de Janeiro, Brazil. Marksmanship will be an important part of the Rio Olympics. Nearly 400 top shooters from around the world will compete in rifle, pistol, and shotgun events. The shooting competitions will take place in a large, modern sports complex originally created for the 2007 Pan-American Games at a cost of $53.5 million. This complex, located within the Deodoro Olympic Park in Rio, offers roughly 30,000 square meters of improved areas on the 125,000 square meter site. Brazil’s Olympic Shooting Center (also known as the National Shooting Center) is an impressive facility. In size, scale, cost, and capabilities, Rio’s Shooting Center is without rival in the Southern Hemisphere.
