two different bullet weights (165 and 180).
three different styles of bullet (180 hard cast from Dardas, FMJ and JHP).
accuracy at 15 yards, rapid fire:
recoil mild to stout, plinker lead was a cupcake (AA#5 at 5.6 charge weight). no leading, took a bore light with me to inspect after each magazine.
AA#7 and FMJ told me a story at 8.8 charge weight.
Autocomp 6.8 charge weight and JHP somewhere in between.
my other three GLOCKS all Gen 4 (G20, G29, G19) all required some break in time. all three of them USA.
G22 is Austrian, good out of box, zero BTF, all brass recovered, stacked nicely to my right between 4 and 7 feet.
