I always take care of game first. More than once my MLers have gone overnight without cleaning, and I never have had any issues. This year in Virginia, I did reload after taking that big, old buck, and it was five days before I unloaded (shot) and cleaned the little .62. It had been in my truck in a case all of that time, and when uncased, there was no sign of corrosion in the bore or around the lock. I fired it, and then cleaned and there was absolutely no sign of rust. It has been relatively dry, so that was a plus. I've been using mink oil from TOW as patch lube and credit it for helping to minimize rust. REAL BP isn't as corrosive as some of the substitutes, and modern steel isn't as porous as the old iron barrels were.
