just depends on the powder, projectile and what I am working on. for my between shot method.
I use alcohol and windex (either on there on patches or in an 50/50 form) and an dry patch both sides while shooting pyrodex rs, p, triple 7 and app when using powerbelts and sabots loads.
no clean between shots with bh209 and patch and round ball loads (patch does the cleaning for me)

closer to hunting season, I goto cleaning every two shots, clean bore on the first and an follow up shot.
