I was shooting .323 balls I bought online. I have a Lee .319 mold they fit but I don't feel they are tight enough when I shoot them I use wads and lube over the ball. Not much room left for powder. A while back I found a stash 12ga #00 buck I had forgotten about. I have been taking them apart there is twelve .330 balls in each shell. Track of the Wolf sells .330 balls but I hate paying or shipping and waiting I buy local whenever I can. What are you guys shooting?
