BAT .50 BMG Model EX– Now That’s an Action!, by GAS
A while back, I stopped into Bruno Shooters Supply for a jug of powder and looked into the display case where the new actions are kept. Amid the usual array of BAT Machine, Kelbly and other actions, there was something unlike any action I’d seen before — all I can call it is the BIG BAT (It’s officially the BAT Model EX 2.5). I wasn’t too surprised at the weight (a beefy 13.7 lbs.), but until you lift it it’s hard to appreciate how solid, chunky, hefty, massive (pick your favorite adjective) this thing really is. The action is a 2.5″-diameter, 12″-long BAT for the .50 BMG cartridge. It is simply the biggest, slickest custom action on the planet. In order to give you some sense of scale, I photographed the action alongside a conventional BAT action for short-range Benchrest shooting and I put a .220 Russian case and a .30-06 case into the picture. I’ve handled and fired other .50 BMG actions/rifles before, but this BAT puts them all to shame, as far as fit and finish go.
The action is actually quite conventional in design and execution. The bolt is fluted and has two front lugs with a conventional, although super-sized, firing pin assembly. Any Remington-style trigger will mount by way of a normal trigger hanger, allowing for simplified maintenance or replacement in the field. The loading port is 5.5″ long and the barrel threads are 1.5″ x 16 tpi — nothing about this beast is small! There is a conventional rocker-type bolt release on the left side of the receiver body and a recoil lug is built into the bottom of the receiver. In reality, the action is very similar to any other BAT except for the size and it adheres to all of BAT’s high standards for quality of design, manufacture, fit, finish and just plain good looks. Slide that bolt back and it feels as tight as a small Benchrest action!
Given the BIG BAT’s $3,125.00 sticker price (before options), not many of us will ever have the opportunity to own or shoot one of these beauties (I certainly won’t). However, it is nice to know they exist and can be bought and enjoyed in many places. CLICK HERE for BAT EX configuration options.

In this video Bryan Litz of Applied Ballistics offers tips on Big Bore shooting (i.e. .338 caliber and above). Bryan offers advice on bullet selection and he explains the challenge of handling the blast, noise, concussion, and recoil of big boomers such as the .416 Barrett and .50 BMG.
Bryan goes big … very big, shooting a monster .50 BMG bullpup.

Big Bore Basics — Tips for Shooting Big Boomersby Bryan Litz
There are some unique things to consider with big-bore shooting. One is bullet design. For long-range shooting you want high-BC bullets. You get high BC from heavy bullets and bullets that have low drag. The interesting trade-off in big calibers is that there are a lot more lathe-turned solid bullets in copper and brass available than there are in the smaller calibers. You’ve got bullets that have slightly lower drag profiles but they are made of materials that are slightly less dense (than lead) so they are relatively light for their caliber. With that trade-off, the BCs might not be as high as you think for big calibers, although the bullets are heavy enough that they carry a lot of energy.
Energy really has a lot to do with shooting these big-caliber rifles. As with any kind of shooting, the fundamentals of marksmanship are the most important thing. However, it can be hard to maintain good fundamentals (e.g. trigger control and sight alignment) when you’re burning 100 grains of powder. There’s a lot of concussion (you want a muzzle brake no matter what your cartridge is above .338). It certainly can be challenging with all the muzzle blast and all the energy coming out of the barrel.
For long-range shooting with big bore rifles, you are still looking for the same things that you want with smaller-caliber rigs. You want a high-performance bullet, you want consistent ammunition, and you want a good fire solution to be able to center your group at long range. Basically you’re just dealing with the challenges that the high energy brings, and being smart about your bullet selection.
In the video above, Bryan is shooting the DesertTech HTI bullpup. This rifle can shoot four (4) big bore chamberings, with barrel conversion kits for: .375 CheyTac, .408 CheyTac, .416 Barrett, and .50 BMG. These can be quickly swapped in the HTI chassis, which employs an internal barrel-clamp system.

In the world of varmint cartridges, it’s all about speed. Higher velocity delivers flatter trajectories, and more dramatic impacts on critters. To achieve higher speeds, handloaders have experimented with many extreme wildcats — big cases necked down to a smaller calibers. Here we present what may be the most extreme wildcat cartridge of all, the .17 Incinerator — a .50 BMG necked down to .17 caliber. Created by Ammo-One, a custom cartridge company, the .17 Incinerator offers blistering performance. The special lathe-turned 33gr projectiles* exit the barrel at 5883 Feet Per Second — that’s over Mach 5, five times the speed of sound.
Mach 5 is 3836.35 mph at sea level, which equates to 5626.64 Feet Per Second (FPS). The remarkable .17 Incinerator achieves this stunning velocity by burning over 230 grains of powder in a highly modified .50 BMG case. The velocity of this cartridge (still well over Mach 5 at 100 yards) delivers an incredible amount of energy on target. A hit literally vaporizes a varmint, as you can see from the image below.
It takes a special barrel to shoot the .17 Incinerator. Kent Wilson of Ammo-One, who helped develop this extreme wildcat, explains: “The speeds are so great we had to use a custom 3-groove, polygonal-rifling 1:20″-twist barrel to keep the bullets from disintegrating on launch. The polygonal land/groove geometry reduces bullet engraving, which also helps keep the bullets in one piece. Also we must use solids — regular jacketed bullets can’t handle these speeds”.
Even More Speed — the .17 Incinerator Improved
While the .17 Incinerator is commercially available, there is an even more extreme “Improved” version of this case, with a radical 50-degree shoulder that yields even greater case capacity. The .17 Incinerator Improved (17 IN-IMP), shown below, can hold 20 grains more powder, promising velocities approaching Mach 5.5 or 6189.3 FPS. Now that’s really cookin’!
*Because of the ultra-high velocity generated by the .17 Incinerator, solid bullets must be used. Conventional jacketed projectiles would disintegrate before they reached the target.

Kelly McMillan with his lastest creation — the “ELR Beast”.
The design team at McMillan Fiberglass Stocks is working on a new heavy-duty stock for the Extreme Long Range (ELR) game. This beefy gunstock is designed to handle the heavy torque and recoil of big-caliber cartridges such as the .408 Cheytac and .50 BMG. The stock is also designed to balance the ultra-long barrels favored by ELR shooters and King of 2 Mile competitors. Shown above is the boss-man himself, Kelly McMillan, with the new ELR stock prototype. Kelly calls this “the ELR Beast”. Note how the cheekpiece is slotted to allow unimpeded movement of the extra-long bolt.
Kelly tells us: “Making headway on the ELR Beast. Using Paul Phillips’s barrel and action we have been able to make some progress in both the design and the cosmetics of the stock. I am pleased with where we are at this time. As is, this set up weighs 46 pounds, I suspect we can get this stock to weigh between 8 and 9 pounds maximum, and maybe 5 pounds minimum.”

This 50 Cal Days of Christmas video features some fantastic slow-motion footage of a Barrett .50 Caliber M82. This bad boy pumps out some serious muzzle flash. Watch carefully at the 1:05 mark and you can see the .50-caliber projectile exit the muzzle brake and spin through the ball of smoke and flame. For best viewing, you may want to change your video settings to 720p or 1080p High Definition and view full-screen (using the video controls).
The video carries “overkill” to the max, as the shooter uses his big Barrett to blast Christmas ornaments and a snow-globe. To top things off, at the 2:50 mark, the shooter fires the .50 cal at a pyro-equipped gingerbread house. (The gingerbread shot is taken from a standing hold no less!) The results (at 3:22) are impressive — gingerbread house becomes flaming gingerbread pudding.

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).

Legendary shooter Jerry Miculek holds multiple world records, and has amassed over 80 major championship titles. He is considered “one of the fastest trigger fingers” on the planet. In this video, Jerry puts his skills to the test, using a Barrett m82A1 .50 BMG in a timed speed run. Watch the video, starting at the 1:20 mark, to see this amazing speed run.
Watch Miculek Shoot .50 BMG Offhand. Action Starts at 1:20:
Jerry shoots six (6) .50 BMG rounds in under one second (0.98 to be precise). And Jerry did that standing (offhand) without a rest. What can you say… the man is a beast.
If you look carefully, in this frame you can see a .50-Cal bullet in flight forward of the muzzle brake.
Jerry was a bit apprehensive at first: “This is by far the most horsepower I’ve had in my hands ever in my life. So the learning curve is going to be kind of really abrupt.” But as he shoulders the big Barrett and gets ready to punch six rounds on the clock, Jerry gets enthusiastic: “This is going to be fun guys … six rounds .50 BMG … Time to rock and roll!”
After filming this video, Jerry did more drills with the Barrett and he actually brought down his split times. Jerry reports: “I managed to get it down to 0.16 splits and I outran the bolt a few times. You can actually see that in the closing slow-motion footage. You just can’t expect such a massive gun to cycle as quick as a 1911 or your M&P/ Glock type pistols unfortunately.”

McMillan Stocks has released an updated version of its .50-Cal benchrest stock. The new Super 50 BR features an extended-length “wheelbase” with machined aluminum lower surfaces for stiffness and improved tracking. In the video below, Kelly McMillan reviews the features of the new Super 50 BR:
The notable features of the new Super 50 benchrest stock are machined aluminum shoes on the bottom of the forearm and buttstock. These are machined true to each other for perfect alignment in the bags. The removable forearm shoe is available in either a 3.5” or 5” width. This is significant. Kelly McMillan explains: “You’ll be able to shoot this same stock in different classes just by changing the forearm shoe, and that’s something you can do in a match if you want.”
Engineered to be Super-Strong with Minimal Flex
With the interlocking design of the foreand (with 90° blocks that interlock with the aluminum shoe), this is a very rigid stock. In fact, Kelly says: “We’ve molded several 90° angles [into the fiberglass section] that actually increases the stiffness in addition to the stiffness that the aluminum offers. We think this is probably the stiffest fore-end on any stock that we’ve ever made.”
This Super 50 BR stock is approximately 44” long and has a forearm about 20.75” long from the front of the action. And if that’s not long enough, the forward “shoe” can be machined up to 6″ longer to extend the “wheelbase” even further. This stock has a minimum weight of about 9 pounds in Light Gun configuration and a max weight of about 18 pounds (for the stock itself) as a Heavy Gun stock. The Super 50 BR is an ambidextrous design that may be inletted and used both right and left-handed.

30th Annual FCSA Championship Coming Soon
The 30th Annual FCSA 1000/600 Yard World Championship will be held July 3 through 5, 2015 at the Whittington Center in Raton, New Mexico. CLICK HERE to REGISTER.

For a number of years I drooled over every .50 BMG caliber rifle that I came across, I read every article I could find and determined that ‘Someday’ I was going to have one. Well I finally took the plunge and in 2002 I purchased my first ‘Big 50’. Almost immediately I joined the Fifty Caliber Shooters Association (FCSA) and I have since come to immensely enjoy shooting this challenging cartridge and associating with some of the best people on earth.
1000 yards? Heck, for these KO2M guys, that’s just a warm-up — they plan to shoot out to 2500 yards and beyond. A new ultra-long-range event will be held this summer in New Mexico at the NRA Whittington Center. The King of Two Miles (KO2M) match will be held on July 1-2, 2015, right before the Fifty Caliber Shooters Assocation (FCSA) 1000-yard World Championships. If you like hurling big projectiles at very long ranges, Whittington is the place to be in July. The KO2M event is “wide-open” — any caliber is allowed and rifle size/weight is limited only by the shooter’s ability to lift the gun himself. Rifles will be shot prone with bipod.
Two Miles (Well Not Quite)
The name of the event is a bit of a misnomer, as the max range will be roughly 2500 yards. That’s WAY less than a full two miles (3520 yards). KO2M organizers do plan to go all the way out to two miles in the future, but they say their target and spotting technology isn’t up to that yet. Accordingly, the 2015 course of fire will include steel and electronic targets placed at known distances from 1000 to roughly 2500 yards. Next year, hopefully, the max range will be extended to over two miles, but, for now: “Current optical systems do not allow that.”
