RE: TC Maxi hunter or Maxi ball
I've shot maxiball out of the Black Diamond XR and it did good with 100 grains of Goex 2f but at longer distances the accuracy started to fail. In your Diamond you might want to try some 250 grain Shockwaves with 100-120 grains of 2f under them
Roskoe had good results shooting 410 grain Great Plains conicals and I will be trying some of the 385 grain Great Plains with a sub base under them sometime this week. They just came in with the new box of projectiles I orderd.
For close range plinking shoot some of the 320 grain R.E.A.L. conicals and 85-100 grains of powder. They shot really good out of all my inlines.
