5 or 6 years ago I decided to try the 6mmXC....this was before the "Creed-craze" (I'm coining that phrase) and luckily it turned out to be the bee's knee's of a cartridge. I'm still shooting the original 6XC Criterion pre-fit barrel and it's still going strong. Today I sent an email to the same outfit that supplied my original barrel (Northland Shooters Supply) asking if they could order me another....lo and behold they have exactly what I wanted on the shelf! A quick phone call later and I've got another 28" Small Shank savage Criterion, 1-8 twist, 6mmXC pre-fit barrel with the 11 degree target crown on the way! Should have it by the end of next week. ....now I need an action!....My 223 AI might have to be a 6XC for a while!.....I love these Savage rifles. Easy to work on if you have some common sense and a small amount of mechanical know-how. The prairie dogs are in trouble with 2 6XC's shooting at them this summer.
