Sierra lists a 55 grain Gameking bullet in 22 caliber. They should fly out of a 14 twist 22-250, I would presume.
Has anyone here used them? On deer?
they work very well--though for deer i prefer the 55 or 60 gr. hornady spire point.
my friend bob s. has shot several elk with them in both swift and 22-250. one of the elk was shot at over 300 yards, and it went right through, with a near instant kill...
