Maybe you guys can help me out here.
I picked up some 147gr FMJ FP to work up a load for suppressor use. I have never loaded 147gr before. I am using Alliant data for Sport Pistol which lists 3.5 grains at 1.08 min OAL. (-10% for starting = 3.1)
I'm getting a pretty good variance in OAL when seating. 1.162-1.175
At this length, even with the variation, every single one plunks in all my 9mm barrels perfectly. I loaded some up at 3.1, and some at 3.3 and test fired with suppressor. The 3.1 would not extract, but 3.3 did; very good grouping and functioned just fine.
Should I be concerned with rounds that are over max length?
I took some that were over 1.169 and cycled through pistol to see if they were getting set back and none were.
The lengths are that long because that's where I started and they all plunked and shot well so I didn't see a need to mess around anymore with seating. Should I try to shorten the OAL some?
Is there a chance of under pressure and possible squib being as they are loaded so long? Or should I just "choot em"?
Thanks,
