Hey guys, I have a 1911 1899A in 303 savage. The first 1/4" or so of the bore at the muzzle has no rifling probably due to a steel cleaning rod. This gun is all original but it is a shooter not collector. It only shoots 5" group at 100 yds. My options are. 1. Cut barrel down from 26" to 25 3/4". 2. Counterbore the inside diameter to 1/4" depth and see if it shoots better. (Anyone ever do this with good results). Or 3. Leave if be and dont take a hunting shot over 100 yds. Opinions welcome.
