[QUOTE="codyadams, post: 1804647, member: 87243"] Yes, it is. I did a lot of research prior to building it, and funds are very tight at the moment. You should be fine on a standard rem action if you are careful, the issue is the tougher brass like Peterson and Lapua brass won't show your standard pressure signs when you are at the 63000 psi max for the cartridge, Peterson actually tested their 300 nm brass at 75,000 psi for multiple fireings without any failure, it says right in their site. Using a Stiller TAC 338 action and a 28" carbon six barrel, I got the 300's up to 2900 fps in Peterson brass, and the brass looked the same as loads shot at 2700 fps except for the primers being slightly more flattened out, but still not looking entirely excessive, but I know pressures were too high. So the tough brass will not show signs till much higher pressure is reached, which consistently running at high pressure, like 75,000+ psi where pressure signs may be observed, could cause lug set back and possibly other issues in the standard rem 700 type actions. You need to look at velocity using published load data or quick load or something similar, and not exceed velocities listed. With my 24", 2740 fps or so is right at max with VV N-570 and a 300 berger according to quick load, and I will also be HBN coating which usually gains 20-40 fps at the same pressure in my experience. So, I will aim for a load around 2675-2700 fps so I have some wiggle room and keep pressures safe for my action. Optimally a larger custom action would be better, and eventually when I rebarrel I may upgrade the action as well, but this will work for now. [/QUOTE]
