Well I have a lever action 50-140,didn't know there were any other kind. It doesn't have a tubular magazine though, your left hand with 3 cartridges,one between each finger works well, although you usually don't need to shoot more than once at something to kill it. Come to think of it I knew a guy who had a highly modified roller in 50-140, he had to deep seat his greasers so far to chamber them I don't think he could get more than 130 grs in them, regular whiner outfit for sure. I do know one guy who had his C Sharps rebarreled to a 1 in 22 twist 30" long with a 14# bull barrel so he could patch to bore dia a 700 gr paper patch bullet. Haven't heard from him in a while as he was having health problems and isn't shooting much. Somebody clue me in here, what other kind of rifle than a lever action would you expect to find chambered in 50-140? Magnum Man
