I have some 9mm reloads that will frequently fail to extract, resulting in an annoying double feed. Happens one or two rounds per magazine. I have a bunch of them, around 500, that I loaded around two years ago. I was fairly new to reloading at that point, but I can't see that being the issue. I worked up the load, it seemed to function fine at the time, so I proceeded to load a small stockpile.
However, I never shot many of them because shortly after that I started experimenting with cast bullets and that is now about all I ever shoot. The other day I just decided to burn through some old stock and discovered this problem.
I have developed a couple other 9mm loads with jacketed bullets, and quite a few with cast bullets, without a hiccup. I've loaded, and shot, maybe 5000 rounds. My techniques havent changed much in the last couple years. This particular load is the only problematic one I have encountered.
Gun is a full size SR9. It works flawlessly with every other load I have put through it.
Recipe is as follows:
124gr Montana Gold JHP
6.4gr Power Pistol
1.120-1.125 OAL
Winchester SP primer
Light crimp with Lee FCD
Mixed brass
Average velocity is 1175 fps. Yes, this is on the warm side, but that is what I love about Power Pistol. I use other powders for milder loads.
Passes the "plunk" test with ease. Every round that I checked (just a small sampling) fit the case gauge. Extractor on the gun seems normal. Rims on unextracted cases appear normal. Just tip the gun up, and they fall out.
Any thoughts on what the heck the problem is? I have a hard time believing they are over pressure, but maybe?
