I imagine all this has been asked before, so I am sorry... BUT Wanting to go long on the cheap. Thinking about the Mossberg pred in 6.5 PRC. What powders are working for bullets 140 gr + and what BULLETS 140 gr + ?? How long is brass lasting ? Mag primers or no ? On a Mossberg or savage quality gun should I go through the break in process ? I have alot of R22 and IMR 7828 SSC and some regular cut also. I would like to gong out at 1K + before I sign my tombstone. Any help will be a help. Thanks, Ray
