I have used Wonder Wads for over 10 years and can't say enough about them. I shoot Frontiersman catagory in SASS competition. I have not only used the wads in percussion revolvers but in BP cartridges for my .44-40 rifle. With both the pistols and the rifle, I can shoot a full day's stages (Usually 60 rounds each for both rifle and pistols) and not need to clean the bores between stages. I have never experienced an accuracy loss in either pistols or rifle. In the evening, the bores clean easily using plain soap and water or Ballistol and water.
