At 2400 Yards, Litz Tests Berger’s New .375-Cal 400gr Bullet

Bryan Litz Applied Ballistics King of Two Miles .375 caliber 400 grain Berger Bullet

Berger Ballistician Bryan Litz has been preparing for the King of Two Miles match next week. He’s been out testing a VERY high-BC bullet — Berger’s new prototype .375 caliber 400-grainer. In the photo above, you can see Applied Ballistics intern Mitch Fitzpatrick (flanked by twin LabRadar chronos) shooting at a target set at 2400 yards. Next week, at the King of Two Miles event, the challenge will be even greater — Bryan and his team will be shooting out to roughly 3600 yards.

Bryan reports: “We’ve been preparing for the King of Two Miles match next week. Last Friday we shot 2400 yards at Thunder Valley Precision in Ohio, measuring time of flight and refining the custom drag model for our bullet. We are logging flight times over three seconds and the bullet is still supersonic at 2400 yards! Tomorrow we’re shooting 1800 yards as a final verification before we load up and begin traveling out west.”

OPTICS for Extreme Long Range
Bryan is running Nightforce ATACR scopes on his .375 rifles. These ATACRs offer 120 MOA (or 35 Mils) of elevation. That’s impressive, but you still need more “up” for these extreme distances.

Bryan notes: “No scope has enough elevation to dial direct to two miles even with these large-caliber, high-performance rifles. You need some kind of external adjustment, or use a steep rail (e.g. +80 MOA). This works but can sacrifice your ability to zero under 1000 yards.”

This video shows a hit at 2400 yards with the .375-caliber bullet. The target is 8’x8′ square. The targets Bryan will shoot at next week’s King of Two Miles competition will be up to 1200 yards further than this. (Two miles is 3520 yards).

If you’re interested in this kind of Extreme Long Range shooting, consider attending the Applied Ballistics Seminar. The next seminar will be held July 18-19 in Michigan. Bryan says: “We’ll be sharing our experiences and lessons learned in the Two Mile shooting match among many other things we’re working on.” CLICK HERE for Seminar INFO and Registration .

Buell’s Beast: Heavy Artillery for ELR and 2-Mile Match

Click above image to view full-screen photo.

Our friend Darrell Buell has a new Beast — a monster 64-inch-long .375 CheyTac that weighs more than 70 pounds! Designed for ultra-long-range shooting (two miles and beyond), this beast represents the state-of-the-art in extreme long-range rifles.

Darrell Buell ELR Rifle .376 Cheytac BAT Action 35

Darrell reports: “This rifle is pretty much purpose-built to shoot 2+ miles extremely accurately. It is a .375 CheyTac (lengthened) built on a BAT 2.5″ action. The custom 35″, 1:10″-twist Brux barrel is a fat, 2″-diameter ‘straight taper’ with fluting. A custom 5″-long muzzle brake is fitted at the end. All barreled action work was done by R.W. Snyder Custom Rifles. The stock was created to fit the build by PDC Custom, and the massive muzzle brake as well.” The “bridge” at the end may look like a barrel block, but it’s not — the barrel completely free-floats. (The Picatinny rail on top of the bridge allows use of an overhanging bipod as an alternative to the JoyPod).

Darrell has lots of elevation on tap: “With 150 MOA in the Ivey rings, another 20 MOA in the scope rail, 55 MOA in the Nightforce Competition scope, and 10 MOA in the FCR-1 reticle, there’s an impressive +235 MOA available.”

Texas Triumph: 3600-Yard Shot with .375 CheyTac

3600 yard shot .375 cheytac texas

They say “things are bigger in Texas”. Well shots are longer too. In this video, a shooter successfully hits a 1-MOA target at 3600 yards with a .375 CheyTac rifle. That required plenty of elevation to compensate for the bullet’s drop over its 2.045 mile trajectory. The shooter, Jim Spinella of New Jersey, needed a whopping 60.2 Mils of elevation (26.8 in rail, 22.6 in turret, 10.8 hold-over). Jim had to wait a long time to confirm the hit — with the metal gong situated more than than 2 miles from the firing line, it took the bullet 7.2 seconds to hit the target.

Big 350gr Bullets with a Wicked BC
The 3600-yard hit was made with CheyTac factory ammo using 350gr CNC-turned bullets. Spinella was impressed: “The ammo chronographed out at 3080 fps with velocity differences at no more the 7 fps, which was outstanding. We found the true BC over 3600 yards to average 0.810 (G1)”.

NOTE: You see three shots in the video, but Spinella took many more before a hit was achieved: “We peppered the 2 MOA area around the target with a couple of dozen rounds. We hit the rack the target is hanging on twice. This was a fun experience, and we took a lot of data away from it. We put a lot of work and planning into this in order to be in position to be lucky. So many things are ridiculously magnified at that distance. Every 1 mph change in wind [moves the bullet] about 6 feet. As the barrel heats up the velocity changes with it [and] 10 fps velocity differences, shot to shot, are almost 5 feet.”

This ultra-long-range adventure took place last September at the FTW Ranch in Texas. Spinella worked with a team of experts from Hill Country Rifles, builders of the custom .375 CheyTac rifle, to achieve a 3600-yard shot on a 36” round steel target. Hitting a target at 2.045 miles is no mean feat. That 36″ gong represents slightly less than 1 MOA at that range. A lot can happen to send a bullet off target during a 7.2 second flight.

CheyTac Caliber Comparison — .375 vs. .408
The shooter, Jim Spinella, prefers the .375 CheyTac to its .408-caliber Big Brother: “I shoot both the .408 and .375. Both are great ELR rounds and will get you out there a long way. In my experience, the .375 will get you out there a little bit further. My preference is the .375 Cheytac over the .408. This has nothing really to do with external ballistics. It has to do with fouling. My .408 will go from stellar accuracy to terrible between 40 and 45 rounds. It happens that quickly and accuracy returns after cleaning the barrel. I have never experienced this with the .375. After 100 rounds there is minimal copper fouling with the .375, but I clean around this round count. I don’t know why there is heavy cooper fouling in the .408, but it is common to this round and other shooters who shoot it regularly. That said, I lightly clean the .408 using Wipeout and go back to having fun with it after about 30 minutes.”

Texas Shooter Nails Target at 3650 Yards with .375 CheyTac

Report based on story by Vanessa Oler
Could your rifle hit a vehicle-sized target located 2.07 miles away (i.e. 3650 yards)? Well Billy Carter’s .375 CheyTac can. Last month, shooting at the NRA’s Whittington Center, Billy Carter hit a 12’x12′ target at the confirmed range of 2.07 miles. Carter was participating in the Whittington U Extreme Long Range III Course. Carter’s 3650-yard hits set a new Whittington U program record for long-distance shooting with a sub-50-caliber rifle. At that distance, 1 MOA is 38.22 inches! Edge to edge, a maximum 3.77 MOA-diameter circle would fit inside the 12′ x 12′ square target.

About the Rifle and Load
Carter’s M200 Intervention is chambered in .375 CheyTac. The beast weighs 31 pounds and measures 53″ overall, as fitted with 29″ barrel and muzzle brake. The optic is a Vortex Razor HD 5-20x56mm (MOA-click version). This First Focal Plane fat boy features a 35mm main tube. To reach out to 3650 yards, Carter was running a whopping 136.5 grains of Retumbo powder in his .375 CheyTac USA brass. That was ignited by Federal GM215M primers. All that Retumbo was pushing the CheyTac USA 350gr “Balanced Flight Trajectory” bullet, a custom copper-nickel-alloy projectile.

Hits on 12’x12′ target at 3650 yards (2.07 miles)
Two-mile engagement at the Extreme Long Range III Course at the Whittington U on April 24, 2013.

How the 3650-yard Shot Was Made
2-mile 3650 yard rifle Carter enrolled in a series of Long-Range Marksmanship courses under the guidance of Jon Weiler, a former U.S. Army Sniper. In 2011, the NRA selected Weiler to help launch the Whittington U long-range training program. Progressing through the long-range courses at Whittington U, Carter began to realize his .50 BMG and 338 Lapua were insufficient for the upcoming Extreme Long Range III Course — with targets increasing in difficulty from 750 yards to 3650 yards. Carter heard industry insiders hinting that Australian sniper teams were using a .375 CheyTac to shoot at 3000+ yards. So Carter called CheyTac USA and ordered a M200 Intervention in the .375 CheyTac chambering.

2-mile 3650 yard rifle The first day of the Long Range III course, rifles were sighted-in at 500 yards and students engaged targets at 1200 yards. On Day 2 a cold front and driven snow made shooting near impossible. So, on the third and last day, Carter and the other students decided to go out as far as possible.

This range had four targets: 1890 yards, 2970 yards, 3040 yards, and 3650 yards. Carter figured he could skip the first two, but Weiler said “You have to build up to it”. Carter recounted, “I took 15-20 rounds to work my way up to the 3040 target. At that point you have to take a break. I pulled out my kestrels and started doing the math. My scope had no more vertical space, so I was forced to use five MOA at 3040, then calculate a full value 3 o’clock wind. Basically speaking, I was shooting out of my scope at that point. And hoping. ”

The first three shots, I wasn’t there and I knew it wasn’t going to work. But then I got close. The adrenaline started rushing and I couldn’t stop. I’m almost there, I thought.” Weiler, at the spotting scope, kept an even tone: “Same hold.” Carter shot again. Weiler let the excitement rise in his voice: “I can now say you’ve hit that 3650 target twice.”

Interview with Billy Carter

Carter is V.P. of Carter’s Shooting Center (CSC) in Houston, Texas. CSC is one of the largest private firearms retailers in the country.

“This was unreal. To think just a month before, I didn’t even know the velocity of my load! To pull off a two-mile hit was such a rush… it was dream come true.” Carter gave credit to Weiler: “John was an excellent instructor, designing the course to help you stairstep your way up to incredible distances. It wasn’t like you were just going to spend all day blindly shooting at some impossible target. He teaches you how to succeed at shooting long distance by starting with the basics — correct prone stance, trigger control, and rifle positioning.”
