Anybody know much about the Sherman improved chamberings? Word on the street is that the 338 Sherman and 338 Sherman Short can push a 338 250gr Berger at 2860 in both a long action and short mag case.

I know very little, but I hear nothing but good things about all of the Sherman rounds.

Great round. Built mine on Bighorn Origin Action, WestTexas Ordnance Switchlug, and 22” Bartlein Barrel. Shooting 230g Hornady ELDx and H-Varget. Getting 2900 MV. Didn’t get to hunt with it in 2019, but looking forward to 2020 hunting season.

About time you posted a thread on this cool cartridge. It is still really interesting to me, although I am in the middle of a 338 Win Mag. It might be a future project, and Tony verified he still has the reamer.

I have almost a lifetime supply of Norma brass, and my barrel is apparently supposed to be shot out (3500 rds) although I am still shooting in the .3s. Next bbl will be in .338, since I am already set up with Badger bottom metal and 338 AICS mags.
