...many, many, many feet!
I watched my buddy pop a 22 lb. gobbler at 210 yds ranged by laser with a 17 HMR from a 14" scoped contender and that bird fell over dead! POW! If I had not been there I would have called him a liar. In the right hands that little tic-tac can and will wreak havoc on medium sized game.
Don't underestimate the power of speed. 2500 FPS is enough for most situations. God bless Dave Emary of Hornady.
