[QUOTE="Bravo 4, post: 1041590, member: 8873"] I have pushed my 16.25" barreled rifle to 1700fps with the 750 Amax. It may get more but I quit there, I was shooting without the suppressor and the recoil got pretty fierce. The picture is a 750 Amax loaded right off the lands @ 4.2" (with an Amax next to it to show seating depth). They will not load in the Savage long action magazine and I have to pull the bolt to get the Amax rounds to eject. However, when loaded with pulled (and sized) M33 and API projectiles it will eject a loaded round. A flat point or round nose bullet will load into the magazine. The cartridge is a cut down .300 RUM, about .25" longer than a .50 Alaskan. With a longer barrel you may get the velocity you posted above, maybe a bit more. Might be worth looking into. The problem I have run into is that it headspaces on the case mouth and so you have to get the brass cut just right. [/QUOTE]
