hot ammo question
First, apologies as this relates to a 40 cal xdm. Why I am asking here is that it relates to some ammo Mike Willard made up for me before he passed, a scalding hot 165 gd at 1325 fps. What happened to me yesterday I have never seen or heard of before, so since this forum deals with issues of high speed and high pressure and all the surrounding issues, I come here. I have a g29 and am used to firing hot loads...but anyway...
Here's what happened. I was just going to shoot my xdm because I was bored, and it had been a while since I shot it, so I carried it outside with a few of Mike's rounds in it. Full mag.
I fired the first round, and enjoyed the feel. I looked down on the ground, and an unfired shell was on the ground. I shot a few more rounds, and went inside. The uncertainty of what just happened made me pause and think. So I loaded up the gun just like it was before, went back outside, and the exact same thing happened. I think the shell jumped out of the gun somehow....I don't know
Now I'm really perplexed. I fill the mag up with some 180 grain federal hst.....go back out, and viola....no problem, no issue.
So....I'm completely lost and perplexed. I think the issue was with the ammo...I do have a stronger recoil spring.
The xdm appears fine, fires normal ammo ok. Next weekend I'm going to shoot it more to try to figure out what is going on.
