With a set trigger to boot , that's a big + . One old 45//60 I was shooting a while back started that way , tumbled the bullets that it should have shot good . After scrubbing and de- leading the bore , then last scrubbing it with gum turpentine and getting down to the bottom of the groove . I tried shooting the same bullet with a copper gas check installed . Bingo it shot perfect round holes , good groups and believe it or not scraped the bore enough that the little specs that I thought were permanent were gone . After a couple hundred bullets with the gas checks ran through it , the gas checks were not needed . ,,,DT
