Open post date of April 2013, first time I've seen this thread. First off I own the p mag, cheapest mag on the market and sometimes runs like it. You could try some dry spray lube inside of it and it should help. I have AICS mags, AlphaII mags, and Accurate. The Alpha's swell a little so are a little tight when inserting in bottom metal. I like both the AI mags and the Accurate mags equally.The Accurate will allow a little longer bullet without any altering of the mag, plus they are less money. An Accurate will allow you to put 12 rounds of 6Creedmoore type ammo in a 10 rounder and 11.308 type ammo in it. I bought mine from Masterpiece Arms for $66.00 and a 4 round mag extension that they sell for $34.00. I can run 15 rounds of my 6mm Competition Match at a coal of 2.860" with no problem and will handle up to 2.90"+.I can run the 2.860" in the AICS mags without altering. Check around most places that sell the Accurate mag sell them for about what I paid for them, or buy some good used ones.
