RE: I rediscovered Borebutter this weekend.
dont have to tell you all..bore butter is nasty when weather here in pa. gets below freezing with PATCH/RB.using maxi-balls, i had no major problems..i dont have to use that bore butter now below 32 degrees as i am using powerbelts now.if i shoot a rb in cold, as rb said, i use hoppes blackpowder lube on my patch and no bore butter in bore.i think your permatex might be a good lube in cold for rb and leave bore butter home.
