[QUOTE="jbs2014, post: 1838028, member: 94052"] Not sure what sort of Semiautomatic action, perhaps something similar to what Vigilance rifles or Alexander Arms uses. As far as cartridges go, something between .338-378 WBY and the .338-.408 Cheytac case capacity may work. I can get my .338-378 to push a 300 grain Berger to about 2950 or so before pressure signs occur, I have read accounts on this forum of the .338-.408 Cheytac getting to 3300 FPS (with a 300 grain bullet) or so depending on barrel length. If I remember correctly Rocky Mountain Bullets built their 325 grain bullet for MVs of 3200 FPS or so. A .338 bullet at 3000-3050 may be easier on barrels than the .338-.408 as well but offer better performance than the .338-378. 300 or 325 grain bullet out of a semi-auto platform at 3050 or so would be pretty cool, and such a platform would have other applications besides hunting. Can the .338 AI propel a 300 grain bullet at 3050 out of a 28-30" barrel? Just curious, I dont own a .338 AI, but if you can get a 300 grain bullet to 3050 I may consider buying one. [/QUOTE]
