You asked how many shots before cleaning. Note that there is a difference between cleaning, and wiping for fouling control between shots. Both involve pushing damp patches through the bore, but cleaning is just that, removing all fouling from the bore. Wiping for fouling control is not for removing fouling, although some is pushed out in the process, but for introducing moisture to keep the fouling moist and as uniform as possible. Major differences are a looser fitting patch/jag combo for wiping, and fewer passes.

I am also a competitor, not a hunter these days. I have no experience with loads that lend themselves to repeated shots without blow tubing or wiping. Mine are too tight or close fitted for that.

I know nothing about managing a .45-120. It would be about my last choice if advising on a first BPCR, but you have taken on the challenge and I wish you well.
