kc - I understand the attraction of shooting black powder. However, I didn't understand if you were shooting BP for the sake of BP or to shoot some older guns.
BP is both more costly to shoot and tougher on the guns. If you wish to shoot older guns alot and can forego BP in favor of cheaper, kinder-gentler loads, then consider low pressure/light charge weigh nitro loads. The #1 difference in BP vs nitro loads will be about 5X the price of powder - say a quarter vs a nickle per shot. Shoot BP when you "need to," and nitro the rest of the time.
