Yogi, 220 grain of FFg give me just over 1000fps with a 1500gn 1.0" ball in my cartridge gun and is mild, so I imagine +-100 grains will be a blast. Top end is around 1400, but I always load several smokeless roundballs at 700fps when I go to the range in order to do exactly what you said, put big holes in stuff! It kicks no more than a 30-06, kids can shoot it, no one drops the gun, and everyone loves to see big holes in their targets. Fun all the way around.
