ok, i got 10 of the dics with my gun and i shot some the other day and i was wondering if i had to buy new discs for every shot or can i reuse them and if i can how many times may i use them? after i shot my gun the other day i cleaned it all up and i was wondering what i have to do after i cleaned it all up what i have to do, anything?, i put some bore butter down the barrel, do i have to wipe that all out before i shoot next time, thanks, who_else
