I know tons of whitetails have been downed with .22s and I am not saying that a .223 with a 55gr pill isnt sufficient and am not going to argue it with anyone. I just want to know whether a 70gr barnes triple shock at 22/250 or 22/243 velocities will be a good whitetail rifle for ranges out to say 400 yards. What about 90gr bergers? Would I get a pass through if I double lung em with these bullets at these ranges? So basically is a .22/6.5x47 shooting the above bullets going to be a decent critter getter for the wife? BTW she is a good shot and isnt going to take a marginal shot.
