I once had a customer who was the Massachusetts indoor State pistol champion. He had a super duper wad gun built that he used in his endeavors. He moved to NC when he retired and tried the wad gun and his miniscule loads at 50 yards, the load was not stable at 50 yards, he had every conceivable shaped hole scattered all over the paper. He came to me for advice, thinking his super duper wad gun had gone farther South. I asked the load, he says 2.8 gr BE, which I was astounded that the bullet (200gr LSWC) even got out of the barrel . I told him that I shoot 4.2 gr BE with that bullet try bumping the charge up a mite like in the 4.0 gr range. He did and the accuracy returned. The bullet just wasn't stable past 25 yards.
