New or stub? I've been shooting .44 mag carbine level loads in my inline muzzleloaders with complete sucess and happiness for a number of years now.I even bought a couple lever gun .44's but never could get the same accuracy as I get from my frontstuffers. My Omega and Black Diamond XR's are both MOA class rifles.Never could get a lever to go less than 3 inches for 3 at 100.Yes its good enough but not good ENOUGH. Know what I mean? I think one of the differences is the twist rate. The levers were 1-38's and the ml's are 1-28. I'm thinking , if I can get a barrel blank with a groove not over .429-.430 and a 1-28 I'd be on my way. I noticed the H&R makes a 444 barrel with a 1-20...Could down load the .444...But .44 Mag brass is alittle easier to come by.Are the new Remington production .44 barrels better in their tolerances? How's the accuracy?
