Please don't abuse me too badly here as I am a novice. I know I will probably get as many opinions as responses.

I am shooting 295gr Powerbelts in front of 100g. Pyrodex pellets.

What is the desired cleaning between each shot. I was wanting to do some testing of the scope setup / range of this load, but I want to be sure and clean as needed so that doesn't factor into setting up everything else.

I am really wanting to see how far I can accurately shoot this load.
75/ yards
100 / yards
150 / yards

Was thinking of trying Hornady sabots.......as I really like the new Hornady SST's for the 20 ga. They shoot SWEET !
