fwiw, I've been m/l hunting for over 20yrs and shot quite a few deer with one. I use 100gr pyrodex and 240gr Knight jacketed hp bullets (sabots) and have NEVER had one not work perfectly. Small entry hole, 2" exit, loads of blood and dead deer shortly. I know its old school compared to all the new fancy powders and bullets out today, but honestly....I don't see how it could get any better which is why I've never switched. I've killed deer from 20yds to about 130yds, excellent performance every time. Don't fix it if it ain't broke
