Really? Maybe I should just assume you are exaggerating for hyperbole and after a second thought maybe you can agree Browning was a genius even if you have to clean some of his designs from the muzzle? Do you realize most (maybe all) people cleaned through the muzzle for a hundred years before someone imagined a fix to a problem nobody was having?
I’ve heard it repeated many time how muzzle cleaning will destroy a lever guns accuracy, but I’ve not seen any data or evidence of this. I have a couple lever guns at the century mark in age, always cleaned through the muzzle, and they are accurate as heck.
Muzzle cleaning equals bad accuracy is pure BS. I subscribe to cleaning from the breech if I can, and if I can’t, not a big deal to clean from them muzzle.
