this maybe common knowlage and then i appaligize and will feel real dumb. as i am disabled i got a lot of time to tinker around with stuff and began to try diferent balls paches and stuff i found that if you use 0buck .318 to .319 and a .0015" patch lightly buttered in a Tc Cherokee backed up by 15gr ffg the combanation works great you get 658 ball pr 5 pound bag at $12.00 the patches look good and are easy to load group are real tight just under 1"@ 50yds compared to .311 balls for $8.00 per hundred
