Thread: .243 for 500m shots

I remember reading an article many years ago which basically said don't go by energy alone. The author talked about momentum as being the biggest factor in how a bullet penetrates and performs [construction would be in there now as it's improved over the years]. I think its the combination of twist, bore size, and speed[ probably other things I can't remember but you get the point]. He finished his article by saying a 220 swift and a 4570 have approximately 1000lbs of energy at the muzzle and if you were facing a charging cape buff what would you rather have in your hands? Food for thought once the range starts getting out there
