    I'm building a rifle and decided to go with 300 ultra mag. What is the best bottom metal to use to allow for the longest OAL. Or with this particular catridge would i be better off going with a single shot follower

    When I had my 300RUM Sendero I went with the wyatt extended box magazine, easy to install myself and if I remember right it increased my OAL in the magazine to 3.600, I could be wrong on the length, check out their site. My sendero was like a weatherby, extreme overboar, could almost load out to 4.00 and not hit the lands. A friend had the same problem with his 7RUM Sendero. For what its worth. Good luck
