UPDATE: Yesterday, I took my 1006 and 1066 out and fired 50rds (25rds in each) of my PPU reloads (180gr Hornady FMJ FP, 7.0grs of Unique and WLP primers). I recovered 43 of the 50 spent cases. I brought them home and carefully examined them (even with an 8x loupe). Everything looked good. I then resized/recapped them. They held the resizing with an internal diameter of .395 to .396. I proceeded to expand and reload load them with more of the Hornady bullets, the bullets were held tight.


I've been thinking and wonder if any of these reported cracks in the PPU cases upon initial firing have been in a S&W 10mm or have they all been in Glocks. Glocks are reported to have generous chambers that could contribute to the cracking. I'm not saying that's the reason or bashing Glocks (I own and shoot five of them myself, although not in 10mm), just wondering.
