I'm new to muzzle loaders and had a couple questions. How does the powders compare to smokeless when it comes to storage and shelf life? I live in the south and have a lot of humidity to deal with. I don't have a problem with smokeless powder, as I'm still using powder that I've had for 10+ years. Someone told me that pyrodex has a short shelf life. Also, I've got some of the Pyrodex pellets that I got a year ago and the container isn't air tight like a bottle of powder. My loose pyrodex and 777 that I bought last year both should be ok as they are in the same type container that smokeless comes in.
Another question, after firing, there is a rough spot in the bore at the bottom of the barrel. If I run a dry patch to the bottom of the bore, I almost have to disassemble the gun and push it out the rest of the way instead of pulling it back out. The bore has had very few rounds through it (mainly for this reason), does it just need more rounds fired to smooth out? Lately, I've been using wet patches for the first two between shots to keep the patches from sticking.
