Rigmaster ; I've been studying the 338/375 Ruger and you have some of the most comprehensive data I've read. I have all the parts to start except the reamer. Where did you get yours??My requirements are, available and affordable components and the ability to safely and reliably reach or exceed 2700 fps with 300 gr bullets from a 28" barrel. And a stainless Ruger M77 action.
Are your barrels 10" twist?? I have an H+H length mag box that I can fit to the action if needed to get the velocity but will start with the standard mag box and 24" factory barrel to get a big game rifle ready in time for late season caribou.
Any info any of yall can provide will be very much appreciated .
