area of .22. Gee, that makes it EIGHT times as good as the load Jeff said would suffice.
40 grs at 2200 fps is a pretty fair lick, but if it's a spitzer ball rd (Jeff didnt say anything about it being a softpoint in order to work as he claimed) it aint much, actually. 430 ft lbs. 80 grs at 2200 fps is of course 860 ft lbs. Now THAT'S pretty likely to be a disabling hit, even WITHOUT expansion or fragging of the bullet.
