Agreed, the M3A1 with can was like a canoe paddle hitting the backstop. The bigger bullets are great for the 9mm, I loaded a RN lead meant for 38Spl and about three gr of B'seye, it was super. Lots of obturation and lots of smack. I never loaded bigger than 150...standard barrels worked great with this stuff too, remember though it's still a close range weapon, like 60 yds max for best results...
