It's all in "how" ya clean a m/l er. Im so lazy , I have a hookup to a laundry sink hot water faucet. 1 insert 1/4" tubing into bore completely to breech plug , hold finger over flint touch hole , turn on hot water faucet until the barrel exterior gets hot to the touch , turn off fawcet , commence with drying patches , w/shot of WD40 to prevent sticking. All in all , meby 7 to 10 mins.. Tooth brush the lock under hot water fawcet , dry , lube , and reinstall. Stand rifle in corner muzzle down , wipe once next day to catch any moisture frim around breech plug , and store gun away. When I go shooting with the neighbor , His gun gets cleaned right after mine. Beyond lazy man's , easy peasy. No Pyrodex.
