I bought a rifle barrel that was supposed to be a 45 cal for a .450 marlin. The dia of the groves is .458 like it should be but the land dia is .448. Should I be concerned about this or is it just a really tight barrel.
Travis
No I should not be concerned or no it isn't a tight barrel? So should I try to have the barrrel reamed out or just get a .448 pilot for the reamer.
Travis
The Barrel is correct (.005 lands each side = .010) ! Get the .448 pilot for the Chamber reamer and you are good to go ! DO NOT REAM THE Rifling in the BARREL !
