PDW292:
When I researched the ballistics through the Ohler ballistics computer program for my M-70 264, I found that the the 270 Winchester's ballistics and the 264Winchester magnum's ballistics almost identical and that the 270 used less powder. The advantage that the 264 is it superior ballistis coefficient bullets resulting in better long range performance. However, the 257 is a power house in a small package, a little less powerful than the 270 Winchester. The 257 is under rated and is a fine deer caliber.. On the other hand, the 264 is more powerful than the 257 Roberts. As far as I know, Remington is the only supplier of .264 ammo.
