Fellow GTers, So I have loaded around 400 rounds so far and all of them have fired without any problems. My loads seem to be very accurate too so I'm happy. However, I don't have a swager or swaging die so I have been reaming primer pockets. I think I overdid it this time because the last 50 rounds I loaded mostly offered little to no resistance at all when priming. I had to check if a primer actually had gone in a bunch of times because I did not feel a lot of them. I know the case acts as a gasket but I would like to ask if there are any issues I should be concerned with when the primers are not tightly seated. I am using 24.6 grs of H335 pushing a 55 gr FMJ and I am using Winchester #41 primers. I am loading for two ARs. I have noticed that the #41 primers are thinner than the BR4s. The BR4s are generally harder to seat (or you feel a bit more resistance when they go in). Anyway, should I be concerned about this?? I don't think they are loose enough to fall out of the rounds inside the magazine when cycling... I am asking about issues when firing.
