Hi. Walmart was clearing out TC Maxiballs for $1.00 a box, so I bought 10 boxes of the 320 grain. Does anybody know the diameter of these things or tried shooting them in a CVA inline like my Buckhorn? All I have used in the past were Powerbelts. I know you're supposed to use .490 roundballs for a 50 caliber, but I don't know on conicals since they don't use a patch. I also believe that they need to be within .010 inch of the bore diameter to be legal. Thanks for any info.
