So this is an odd question. I'm looking at starting reloading 9mm for a carbine. My concern is that I've recently picked up Lyman's reloading manual and seen quotes for a few others that state a max charge for a specific round, in this case 7.6 grains. However, the manufacturer of the powder (Alliant) lists the max charge at 8.5 grains which is significantly more. (This is a slow powder) My question is, are all of these stats generally withing the standard max PSI rating of the round which for 9mm is 35,000PSI, or is there a chance some could be rated +P or +P+? The rifle I plan on using it for is rated for all of them, but I'd rather not beat it up too much if possible. I still want a quick round though. The numbers I've seen from 8.1 grains or so is insane for a 9mm.
