Put the leather in olive oil and let it get in the leather. Cut the wads after letting the leather hang a day or so. Did a over powder card, then leather, then shot and another card. Also did powder card shot and then leather. Either way pattern was better than with fiber or felt wads. Tried from 1/2 oz to 1 oz of shot. 5/8 to 3/4 shot best with a little less fff powder by volume than shot. Also tried 7 1/2, 8, 9 and #12 shot.# 8 or 9 shot will do just about everything I want with the small bore. Thanks again.
