i gave up on bore butter.for me it just doesnt protect as good from rust and fouling as good as hoppes or rem oil.i had nasty burn marks on the barrel next to where the caps goes off and since i switched it doesnt happen anymore. i always like to run a couple dry patchs down the barrel before loading anyway with my caplock and also leave the rod with a clean dry patch down the barrel when snapping a cap or 2 to dry out the barrel.i would unload after each days hunt with an air tool and always use a fresh load for hunting everyday.ive seen guys go a couple days with the same load and kill game but ive also seen my share of hang fires. i also like to run the nipple pick through the nipple before i cap to make sure there is no fine debris and the hole is clear to the powder.
