10-4, probably that big 550gr Lyman or RCBS greaser, one 50-90 weighs 16lbs with the tang sight and is very pleasant with the 715gr paper patch bullets, that said, I have an 11 pound 50-90 that chunks 750gr greasers at 1365 fps for hunting with buckhorn barrel sights, that one boots a little, but, the shotgun butt helps, I wouldn't fire it that way if it wore a military or crescent butt.
