Greetings! I realize that reloading manuals are the holy grail of handloaders, and I have no challenges against them. However, I do have a question.
I know that seating depths can have a significant effect on chamber pressure. Theoretically, bullets of similar weight and profile MAY have similar bearing surfaces.
In my quest to develop a 380 load for my G42, and build a 9mm load with my available powders, I am noticing that Sierra is seating comparable bullets 0.010"-0.030" deeper than Hornady. I am finding that if I lean more towards the top end loads in the Sierra manual for the 380, I am getting a greater degree of reliable function in the G42.
My question is: how much of a difference is this slight difference in seating depth going to impact my loads?
As always, thanks in advance for your help!
