·A second message from me. My M40 is an early gun, serial number in the 11-hundreds and I have no idea how many rounds any previous owners fired through it. I just recently bought it and cleaned it (but not removing the guts from the frame). Then I went shooting.
Two 12 round, brand new magazines and 100 shots no problem, using 165 grain full jacketed bullets. Then, I switched to the 165 grain Federal Hydra Shocks. The problems started.
Again and again, in the first 6 shots from a magazine there were 2 or 3 rounds that nosedived into the feedramp and stopped the slid. Once tapping the slide with knuckles was enough to make it close. After about 6 rounds, no problems. So what causes this kind of jam? I have old gun (maybe a weakish recoil spring?) and new magazines. Any thoughts on this?
