I'm another sucker for a nice long range rifle and a 12 was my choice as well. The Mod12 and 6.5 Creedmoor seem made for each other. I shoot 500m benchrest with mine and so far my best group at that distance is 1.89inches. Mine likes 140gb Berger VLD Target bullets and 42.3gn H4350. I'm getting 2,766fps out of it. Mine is zeroed to 300m because once load development was done I didn't need to shoot at shorter distances. Have fun with it pal.
