I agree with Cajun but if you dont want to render it your self buy pure lard. You dont want to use lard or drippings from sausage bacon because of the salt. But all animal fats will have some salt because the animals eat salt. but the salt content is very low almost to be ignored. still its there and wouldnt be a bad idea to make sure you clean your smoke pole? but then the Black powder is much more corrosive than the salt so You are cleaning your smoke pole aren't you?
