[QUOTE="Death Ray 7, post: 114975, member: 4188"] Yes, you would have to form off different cases than regular .300 win mag. But I think it would easily do-able. But I was hoping that with the longer neck that you could seat the bullet out further (aren't most actions are the same length for .375H&H and .300Win Mag?) and not have to worry about O.A.L. in your magazine. By increasing the shoulder dia. and angle, and seating the bullet further out of the cartridge body, there should be ballistic improvements for the heavier bullets. I've never seen any data for a .300 Win Mag Ack Imp., but I have to believe this is similar to what Bruce Baer is doing with his .308 Baer Cub (.308 Norma Mag Imp.), only this would be off a slightly longer case with increased capacity. And I've already considered the .300 Weatherby, and the .300 Dakota (which is ideal other than you can't pick up ammo at most retail stores), but I'm hung up on the .300 WinMag for some reason. I also realize that the bullet of a factory load would be jumping into the lands, but I think it would be better than nothing. Would I be better off just building a long barreled "stock" .300WinMag caliber rifle and accurize it(bolts lapped, action trued, etc...)? Is there any improvement in ballistics with the .300WinMag Imp.? Does anybody have reloading data for the Impr. version with the heavier bullets? [/QUOTE]
