WGR --- Sure do !!! It's one of my favorite rifles, and I really like shooting BP in it. I usually shoot paper patch lead cast in mine.
Shot my whitetail with it last fall, Goex Express ffg and 485 gr. lead cast paper patched. Shoots about a 2 " group at 100 yds.
I have mounted a scope on mine, my eyes are aging. Almost forgot to answer your question, no you don't have to disassemble
to clean. Just try to not get any water or whatever you use in the action, wipe dry immediately and light but thorough oiling
right after drying. probably cleaning and oiling is total of 10 to 15 minutes. Not much different from smokeless. But with smokeless
you don't have to clean so quickly after shooting, unless its real wet out as possibly when hunting.
As a tip for cleaning, make yourself a setup from some scrape plywood with padded U shaped cutouts for cradling the rifle open upside
down at the range. That way no water or cleaning fluid will get into the action. I usually carry a small amount of rubbing alcohol
instead of water for putting on cleaning patches, in the field hunting.
