Darrell Does 2500 Yards — With a .338 Allen Magnum
What cartridge would your chose to hit targets at long range … extremely long range, as in 2500 yards? Well, for ace competitive shooter Darrell Buell, the answer is the .338 Allen Magnum, a .408 Cheytac necked down to .338. This “super-sized” cartridge flings .338-caliber, 300-grain Berger Hybrid bullets at 3450 fps. That delivers some impressive ballistics at ultra-long range. Darrell got to “test-drive” a .338 Allen Magnum rifle at 2500 yards (1.42 miles) while teaching a Long-Range Seminar at the Legion Operator Training Group (OTG) Facility in Blakely, Georgia.* The rifle belonged to Christopher Sykes.
Shown below is the 338 Allen Magnum (AM) next to a .308 Winchester round loaded to an extremely long OAL. The .338 Allen Magnum is a wildcat based off the .408 Cheytac (Cheyenne Tactical) parent case. The cartridge’s inventor, Kirby Allen, states: “The .338 Allen Magnum, when loaded with a 300gr SMK, offers a legit 500 to 600 FPS velocity advantage over the 338 Lapua Magnum”.
Darrell says: “Yeah, it’s a beast [but] with that brake, it kicks less than my .308 competition rifle. It’s got more energy at 2500 yards than a .45 ACP has at the muzzle. The .338 Allen cartridges are standing next to the SEB Joy-pod, along with a standard .338 Lapua Magnum cartridge. With the excellent muzzle brake on the .338 Allen, I could spot my own hits with just the slightest twitch of the joystick. The rifle was not particularly heavy, consequently the pod would hold the crosshairs where you left them without a hand on the joystick.”
Christopher Sykes, who owns the .338 Allen rifle that Darrell shot, says the barrel life with this big cartridge is about 1000-1200 rounds. (Editor: That relatively short lifespan should keep the barrel-makers happy.)
*Darrell Buell was the lead instructor at the Georgia Long Range Class. Former USA Team Coach Dale Carpenter was assisting Darrell, and calling wind at 1000. Darrell will be teaching a similar Long Range Class next weekend (April 24-26) in western Tennessee. Get more info on Darrell’s Facebook Page.

A video of hits on steel would have been cool to see. What kind of accuracy were you getting at that distance?
Are there dimensional differences between this 338 Allen and the 338 SnipeTac?
Where can i get one and how much will it be very interested
On a quiet day you can hear the barrel being eroded. What’s it good for? 2-300 rounds?
Umm Even if It was zeroed at 1000 Yards Chrisopher Sykes is Full of Shit About only needing 38.5 MOA. LMAO What a Douche,At Sea level 59 degrees with a 1000 yard zero it still needs 62 MOA.Berger B.C. is .419 G7 With a 100 yard zero It needs 77 MOA to get to 2500 Yards at sea level and 59 degrees.Please pass the Pipe Dude.LMAO Maybe he has some Magic Bullets.
Quoted from above.
“Christopher Sykes, who owns the .338 Allen rifle that Darrell shot, says the drop for this cartridge, at 2500 yards, is about 38.5 MOA. Barrel life, Sykes adds, is about 1000-1200 rounds. (Editor: That relatively short lifespan should keep the barrel-makers happy.)”
William, it was a miss quote. You are right. We were using 38.5 at a mile.
1 Moa at 2500 yards Is 26.175″ I know Chris and he’s definitely not full of ####. He knows his equipment well.
Willie, no reply???
What are the details on the build?
Interested in barrel length, twist, contour, overall weight?
