Is the failure always on the last round in the mag? The mag's from the 4516 have these projections to hold the cartridge in place under the limited (last round)spring pressure. These may prevent the round from moving forward during the recoil cycle.I don't know if it's relevant to your problem but my 6906 and 5946 did not have these.
