I have a Henry octagon barreled pump .22 LR and a Big Boy Steel . 44 . They are both good shooters with no bent sites or wood to metal gaps and no cross-bolt add -ons to mess with. I also have three Marlin levers including a .375 and have no problems about using the tube loading on the H.R.A. rifles any more than I mind loading my Savage 99. H.R.A. will never spend a dime to mess with another lever gun company and why would they?
