The inside of the barrel maybe...but the contraptions on the outside are tricksy. My other issue is that we've moved to a new home and I lost my "man room" where I could make a mess. My wife found me cleaning my gun in the guest bathroom with black powder fouling covering the sink and countertops with dirty paches all over the floor. Trying to not chip the tile and stain the white rug were added challenges.

Next project: complete my new man room. I just have to unpack 20 boxes first.
