I went out to the range the other day, firing my usual .40 S&W with HF Red PC.
The first two magazines were, as usual, just fine. My aim leaves something to be desired, but that's another story.
However, after those first two magazines, I began to have a LOT of failures to feed. A lot meaning, 3/4 would not fully feed.
Some fed mostly into the chamber, others just started into the chamber and stopped.
One thing I knew I had right off was "the bulge" which I usually associate with bullet not going in square.
Typically, however, this has not caused my rounds to fail to feed.
After trying to cycle a whole lot of my remaining rounds, I went home and started pulling them. Here's what 3 pulled bullets look like:
I CAN say that a few of them looked like the OAL may have been too much before I pulled them, but not all of them. I get the impression that maybe I just managed to press them in at a slight angle, and at first I was thinking some of them just had too much PC on them, but when I pulled the barrel out of the gun, they would enter the throat just fine (this is on my S&W M&P, btw).
Any ideas what I did to screw up about half my rounds? Suggestions on what to watch for on the next batch?
Thanks in advance, all.
