I am relatively new to reloading and recently I had to return my Sig X-Five to Sig. I received a call back from Sig about a week later telling me there was some etching of the metal at the breech face around the firing pin because of hot gas escaping from around the primers which unfortunately I never noticed. I have spent considerable time trying to determine what the cause is and I look forward to any assistance from any readers who are familiar with this problem. Here is some history about how I've been reloading.
1) Initially I started reloading with Speer 115 gr. GDHP bullets (100) with 5.3 grains of Hodgdon CFE Pistol, CCI small pistol primers, COL 1.125 (Hodgdon recipe).
2) Hornady 115 gr XTP HP, 5.3 gr. CFE Pistol, CCI primers, COL 1.090 (Lyman recipe).
3) Hornady 115 gr XTP HP, 5.3 gr. CFE Pistol, CCI primers, COL 1.075; 2 failures to eject (Hornady recipe).
4) Hornady 115 gr XTP HP, 5.5 gr CFE Pistol, CCI primers, COL 1.075 (increased powder charge). I used 500 Hornady XTP HP bullets.
5) X-treme 115 gr JHP bullet, 5.5 gr CFE Pistol, CCI primers, COL 1.075. (2000 X-treme bullets).
6) I have used various cases such as Federal, Blazer, Winchester, Magtech, Speer, etc and have reloaded these cases between 12 and 14 times.
7) About 33% of these reloads exhibit "blowby" and I've decapped some of them and the primer pockets appear to be within specification but I'm not sure I'm measuring correctly.
8) I clean the brass using the stainless steel pin media (http://www.stainlesstumblingmedia.com/) and have checked the primer depth to find that the primers were not seated at or below .004" so I re-seated about a hundred primers to the proper depth. This had virtually no effect on the problem.
9) More recently I ran out of CFE Pistol and have started to use Alliant Power Pistol powder and have switched to Montana Gold 115 gr JHP. I haven't shot many of these so I have little data.
Any help with this problem will be greatly appreciated.
