[QUOTE="backwoods83, post: 2347160, member: 29890"] SAAMI reamer, elliptical (1.5°-30 to 1°-30) throating reamer used to add .285" freebore. OAL with the bullet out far enough to be engraved is 3.271" with 225s that measure 1.652", just touching enough to stick using a Stoney Point with Hornady modified case is 3.266", 2.500" and 2.495" on the ogive for what it's worth. I also wouldn't recommend this with Norma or Winchester brass, Bertram has 1.3-2grns more H2O capacity and is much stronger. I'm not seeing pressure with this combo, but it could be dangerous in a smaller action and with different brass. I can go up another 1.2grns before I pancake a Fed210M, which is a terrible way to gauge pressure, but typically 210Ms pancake at 70-72k psi, and pierce at around 75k depending on the batch. I'm figuring I'm 64-66k. Brass doesn't actually get worked much at this range, and is fairly easy to resize, especially considering the brand. 3rd or 4th firing for some cases, still requires both hands to fully seat a primer.
