While working up a 9mm load (124gr Berrys HBRN/TP, CFE, & trimmed brass with primer pockets and flash holes uniformed) I took a G19 and a 365 just because they are my two most often carry guns. A little while in I noticed the 365 seemed to be shooting much more accurately than the G19. I attributed it to the load/recipe and carried on. Then my surprise, the G19 was not shooting up to par with my regular factory ammo either.
Inspection showed some lead fouling on the G19. I can almost rationalize it to myself as ‘longer barrel = more pressure’ but I was no where near a maximum load and had only shot about 75 rounds in each. Just for S&G I also verified the land to land and valley to valley dimensions measured at the muzzle are nearly identical between the two firearms.
So… has anyone else experienced rapid fouling with thick plate Berrys or has anyone seen the Gen5 G19 to be more sensitive for fouling for some reason? I had expected the opposite from the limited research I had done on the Berrys before hand. (Can’t find HAPs anywhere)
