I had terrible results when attempting to seat rounds in a brand new CVA Accura V2 using Trip. 7 pellets, Trip. 7 209s and Powerbelt 245s. When trying to fire 3 rounds in a row, after 1 round, I had to push hard to get the round seated. After 2 rounds I had to push with all I had, to the point that the situation seemed dangerous, to get the round seated. Apparently, based on research, this is because Trip. 7 leaves a "crud ring." So I went out and bought Pyrodex pellets and a small pack of CVA 50 cal 250 grain sabots. I plan on changing one variable at at time to try to figure the puzzle out. Has anyone here used the CVA sabots? If so, what kind of results?
