50 American Eagle

[ohnomrbillk]

JD made these along time ago.

It uses the 50 AE case of Desert Eagle fame. It is necked up to 510 to shoot BMG ball projectiles.

He turned the case head down to 7.62x39 size. This makes it a shortened 50 Beuwolf, although I think it predates the Beuwolf iirc.

He ran this as a single shot in an ar15.

IIRC, this ran AA#9 powder, and was limited to subsonic use.

JD's load data has a COL of roughly 2.95"

It is similar to Spook's EBG and the many 510 WSM variants, only a little shorter.

Has anyone here had experience with this round? I have questions concerning case forming.

[HHI 812]

Had one in past, in a 11-1/4" stainless encore barrel, with SSK Super brake. Kick myself for selling it, and didn't work with it much then. But a couple weeks ago, was lucky to find another used one in auction, and won it. A day later, won another auction from a different seller, a set of Hornady 50 American Eagle die set. He told me he found the new die set collecting dust in a local gun shop. When I contacted SSK for load data, only info I got was with AA#9 powder, with 650 gr ball bullet, max velocity was 1042 fps, 24.0/#9 from a 16" barrel. I couldn't find any #9, but tried some 2400. Borrowed a chrony, which wasn't working much probably due to cloudy, freezing conditions, but did get a medium load to chrono 3 shots at 922 fps. Buddy gave me some samples of a 460 gr LFN from a buddy's LBT mold he was casting. Tumble lubed the unsized bullets with some Lee lube. Tried some 296 and MP-300,
and got just shy 1400 fps withe the few loads I tried. Could probably go faster, but didn't load that much, lacking any data to work off from.
