Ran across a barrel the other day matching those specs in a 26 incher. And it got me thinking (dangerous) about running a heavy 77 or 80gn round from a 22-250. In theory it sounds like it should be really good shooting but i dont know of anyone that runs it. Anyone out there with hands on experience with it and/or loading for it? Offhand im expecting something close to a .243 shooting a 75gn projectile. Sounds reasonable to me, but im an idiot so best to ask others with more knowledge....
