... but let me clarify that. COMMERCIALLY AVAILABLE reloads. I wonder how well they inspect components before they load? I know when I do my reloads, I am anal beyond belief on inspecting brass and such before I put it in my press.

But... I was cleaning out some spaces and found a bunch of reloaded ammo I had bought, before I started reloading my own. So I figured a good reason to hit the range and get rid of it. I usually take a broom with me and sweep the area around where I shoot, so I know the brass on the ground around me is mine.

I found this:

No weird noise was noticed, no strange feel... nothing to indicate this happened. I looks like there may be a defect in the wall... see the 'spot weld' looking bulge along the split?

But it was from my gun, of that I am sure. Makes me cringe wondering what could have happened. Sad part is I had 4 different 'brands' of reloaded stuff I was shooting so I can't say whose it was. Good part is I inspected my P229 and all is well.

Stay safe!
