Last time I was at the range with a new P-3AT I noticed some light smileys. Was only shooting JHP - Some Fiochhi, some Remington and some PMC. Got to thinking about it at the range today - somewhat concerned about increased pressure if the bullet was pushed back into the brass.
Didn't have calipers with me so I laid the cartridges down on the bench with mags at the top and bottom. All appeared to have the same OAL prior to loading.
I would fire a round, empty the mag and checked again. The smiley rounds appeared to have the same OAL as the balance of the rounds.
I had picked up some Corbon Self Defense rounds, so tried the same process with them. There was a significant reduction in OAL on the rounds I checked. Couldn't tell if the bullet had been pushed back into the brass or had simply mushroomed slightly. Went ahead and fired the rounds with no problem but now I'm curious. :-?
I'll try to take calipers next trip to see if I can determine whether or not the rounds simply mushroomed.
