howler, i've seen so many different charts each with different info regarding the .204, 22-250, 223, 22 swift, 17. . . . .
all i can say is i've been hunting with a fella that shoots a 22-250 vmax and the bullet passed through a ghog @150yds
my 204 at the same distance with a similar sized ghog and a vmax round didn't pass through but nearly blew the head off the ghog. . . .the 22-250 hog had to take a second shot
all shots were placed in the chest. . . .now i don't know / care about ft lbs at this point in time. . ..but i used one bullet to do the job that two of his. . ..
as said before, MAXIMUM CARNAGE
