Winchester has a new line of ammunition out called the super-x Power Max. in 223 rem they have a 64grain bonded pointed HP. They say that it is good for whitetail sized game. My train of thought has always been that 223 is too small for whitetail. I was just wondering if anyone has used 223 on medium deer sized game with any success, and wondering what peoples thoughts were on this new line of ammo? Thanks!
