A.D.D.
I have a CVA Optima Pro and tried the TC sabots first. I could barley get them down the barrel! They shot ok but would not be fun for hunting situations.
I switched to powerbelts and they load and shoot great!



This is at 100 yards, the 2 on the right were before I readjusted the scope.
I get nice groups with the Powerbelts
I am shooting 100 grains of loose Pyrodex select
245 grain hollow point Powerbelts
