Still been having some issues with my 6xc not shooting as well as I expect and I happened to be perusing the kreiger website and I noticed they don't recommend 5r rifling for any 6mm barrels. Now that's not to say it can't be done but I'm wondering what people's experiences are with this combo good or bad. Mine is a Bartlien 5r, 1/7.8. 28 inches long on a Remington action. It shoots 1/2 moa but I struggle to keep it there and I figure it should be doing better. Any thoughts?
