[QUOTE="azsugarbear, post: 2051767, member: 4809"] I have a 338 Improved based off the 338 Allen Xpress design. While I appreciate the additional 150 fps, the real advantages for me were: 1) a more consistent, lower ES and longer brass life with more firings per case (and not having to trim). The fire-forming need not be detrimental to barrel life. You can buy a hydraulic die to reform your brass with no wear to you barrel. Or you can fire-form your brass using about 15 grains of a fast-burning pistol or shotgun powder, topped off with cream of wheat. The powder burns completely inside the brass, compressing the cream of wheat against the chamber, which forms the brass. I do the latter method and find that my brass is 98%+ formed the first time. The only thing missing sometimes is a sharp shoulder edge. The cost of fire-forming in this manner saves both the cost of the bullet, plus some 90 grains of hard-to-find Retumbo, H1000, RL33, etc. So no, barrel life need not be shortened, unless you decide to fire-form with regular ammo.
