I have a question for anyone who either owns a Ruger Old Army Or has ever used one. I purchased my stainless Old Army over thirty years ago and have fed it just about everything one could. My favorite load is thirty gr. of either 3f black powder or triple seven, I even tried Black Mag3, an Ox-Yoke pre-lubed wad and a .457 cast pure lead rd.ball.I swab the barrel as needed betwen rounds. After thirty rounds or so the accuracy goes south. Take it home give it a soap and water bath, scrubbing the bore with a brush she's back to tight groups. My question is what do you folks do at the range to maintain accuracy? Thanks Firelock
