Now I wonder why the .243 would be slightly more accurate out of the box????
Efficiency. Shorter cases burn all the powder. The .308 case is inherently more accurate than most guns. .308, 7-08 .260 and .243 are all based on this case and are all very accurate out of the box.
The 6mm ppc is probably the most accurate gun in the world, it shoots a super short fat case.
Efficiency!
I'm not sure about that but if you say so....
