Is not a 260 a necked down 308?
How can a necked down 308 out preform a 308 at 70 yards?
I got short auctioned BLR and a long auctioned BLR I like the short action better.
I also think the more bottlenecked and restrictive you make the bore in relation to the case, the less efficient the powder charge becomes.
If I want long range splendor me thinks 25 06.
If I want utility me thinks 308
If I want to paint myself into a corner of limited versatility me thinks 260
If I want to kill the bear........... 358.
