 The top three were fired from an M&P9 the next one a G19 and the last (nickel) one is a factory 124gr Speer Gold Dot from the Glock for comparison. The load was a 124gr FMJ with 4.2gr Titegroup. Seated to 1.140 - 1.142. My Speer manual listed starting as 4.0 and max as 4.4 at 1.135. I am thinking I need to back down to 4.0 but would like the opinions of those with more experience. This load will be nothing more than a range load, I do not shoot competitions so PF is of no concern to me. This is my first real venture into pistol reloading, they may be ok for all i know right now. If my .223 primers looked like that I would be backing off the load for sure. And, yes, I know I should have started at 4.0. I didn't and I don't have a good reason as to why.......

Thanks all for the advice. I will be going to 4.0 for the next test batch and probably 1.15. If nothing else I'll get a few more rounds out of that 4lb jug...... My concern was the firing pin channel being formed into the primer on the Glock. And the molten metal looking primers on the M&P. but, none of the primers were pierced. I shot 30 rounds or so, these were some of the worst.

Drop a round in, it should seat all the way with no force and it should fall out when turning the barrel over. Keep adjusting as needed. I run all my 9mm's with t he longest working OAL possible. Different ogives will determine that ie., XTP's, HP's, FMJ's etc. |
