And 12 grains of 2400:
That was benched at 25 yards on the indoor range. That shanked shot in the 8 ring is on me (and the goober who started mag dumping his AR on the lane immediately to my left when I touched that shot off). Not sure what sort of velocity I'm at with that load, I'll have to chronograph it. The gun is a 5.5" flat top convertible model. Pretty sure that'd put a hole in a muley buck just fine.
