I recently purchased a used Kel-Tec 9mm.
I took it to the range, and first shot about 30 rounds of Winchester white box FMJ through it. No problem.
Then, I loaded up a mag of Winchester white box 147gr hollowpoints. It failed to feed on about every other round. The feed ramp on this thing is VERY steep!
When I got the gun home, I took out the barrel and polished the feed ramp very thoroughly with a dremel tool.
Took it out again today, but first went to pick up some Winchester white box 115gr hollowpoints. Fed about 70 rounds with no problem. I then tried another mag of 147gr hollow points - fed fine. Tried another mag of 147gr hollow points - had a failure to feed about halfway through.
When I was at Wally World buying the hollow point ammo today, I compared the 115 and 147gr bullets at the counter. The 115gr one was, of course, not protruding from the opening of the brass nearly as far - so I thought it would feed better, which it did. I had no jams with the 115gr hollowpoint cartridges.
First question - What is the practical difference between Winchester's 115gr and 147gr hollowpoints? Is heavier better? If so, why is 115gr HP even available? I don't understand why Wal-Mart would carry Winchester white box hollowpoints with BOTH bullets weights - although I'm glad they do. Obviously, there is a reason. This is my first 9mm, so I am not familiar with the round - but, I noticed that there is not much of an angle on the outer edge of the bullet - compared to say, .45 ACP.
As it feeds this 115gr HP ammo ok, I have approved it for personal carry now - although I probably won't carry it as my CCW very often.
I'm sure someone knows the answers to my ammo questions - please help!
Thanks,
TD
