Do not get to hung up on the 1/48 twist rate.... I shoot 460 grain Bull Shops from my 1/48 with 90 grains T7-3f and they are almost an 1" long....
I am not familiar enough with the Maxi or Mini ball to offer to much of a comment but the other here have shared their thoughts....
This is not a great target but for me and my eyes... this is not bad with a 1/48 + experimenting
another fun thing I do is shoot clay pigeons placed at various yardages... Hitting one @ 100 is not a problem with these big Bull Shops....
