I hope I am in the correct category here: Today two of our club members have started a discussion that has not yet fully died down. It all started when one of the members (1) saw another member (2) shoot his percussion Hawken. 1: "Nice rifle. Such a shame it's such hard work." 2: "What is?" 1: "The clean up." 2: "No? Swab with hot water, oil and I'm done. You have way much more cleaning to do with all that residue from your FMJ." This has sparked a friendly but hot debate in our club about what is easier to clean. One side claims smokeless is easier to clean because your rifle won't rust away the moment moisture is introduced to the fouling and that you only really need to clean smokeless powder guns every so often. The other side claims black powder is easier to clean, since just hot water and oil is needed to clean it up while you need to worry about instant rust in guns that shoot FMJ. Help me solve this debate in the club so that these oldtimers can stop arguing and focus on the more fun part of our hobby.
