I am looking for the link to the guy at the range with the 60 cal that hits him in the head when he shoots it. I think it was called Big Man Drops Gun but I can't find it with a search. Thanks.
Probably not as much as you'd think. Heavy bullets don't seem to lose as much velocity when fired from short barrels as their lightweight counterparts and at 900grn I think a .600 Nitro certainly qualifies as a heavy bullet.
