I really haven't used any other ball as Ed Rayl recommended .610 to me. I have experimented with patches and loads though.... I started shooting with a very light patch that would burn through with anything over 60 grains FFg. The stuff I'm using now, I found in an outdoor supplies/repair place that has all kinds of outdoor fabrics for equipment and clothing...... Not ticking but more of a canvas type weave...... Quite hard to load and I have taken to punching a wet 4x2 followed by a dry one every 10 rounds (lately, that is, as I'm trying to see the limit of its accuracy). When I'm plinking maybe 20 or 25 before cleaning..... If I could only find the magic combo for use of those wads..... Unfortunately, they open the groups up considerably. Do they ever make loading a dream though..........
