Thread: 223 for deer hunting?

Shot a large bodied spiker this morning with my 223, probably 85-90kgs gutted. Shoulder shot, 150yds roughly, 55gn Hornady training ammo. He was walking slightly away from me, hence why I opted for a shoulder/chest shot rather than head/neck. Angled the shot just behind the shoulder, the projectile travelled thru his vitals and stopped just under skin slightly forward of the opposite shoulder blade. It dropped him on the spot, in his tracks, and by the time I walked over to him he was in deer heaven.
