So as of now, I have approximately 700 rounds through my Mil Spec. About 150 of them were hollow points. 100 of those were 230gr Winchester Ranger and the rest were split between 185gr Winchester Silvertip and 230gr Gold Dot. I posted an earlier thread (I believe in the ammo forum) about how when firing the Ranger rounds, nearing the end of my session, the last round or 2 would not feed. They would just sit on top of the mag. For all of these rounds I have used just the 2 factory mags that came with the box (I have since ordered more). Some forum members felt that it was a weak mag spring that caused the failure, and not the round itself. I agreed, considering how many rounds have been through only 2 mags. But then I tried the Silvertip and Gold Dot and, IIRC, only had one, maybe 2 failure to feeds. So I figured ok, still a weak mag spring. But then later, at a separate range session, I used 100 rounds of plain Jane Winchester 230gr FMJ, with the same 2 factory mags, without any failures of any kind. Can someone enlighten me? I would like to use hollow points for carry (as soon as the state of Texas decides to give me my CHL). Currently, the pistol sits bedside loaded with 230gr Winchester FMJ.
