Glad to be here as I've never worked with the Creedmoor cartridge before. Going to put the barrel on a older 110 action that is currently 22-250. The long 110 action will allow me to seat bullets out far enough to jam if need be. I'll also be using a single shot sled. Got the barrel from a Savage Forum member for $130 shipped. Barrel is the standard varmint weight, 26" 8' twist. It's a brand new take off barrel so will require break in.
