Oh yea, both are single shots, tho the 541s and some 581s were repeaters. Some 40xs were repeaters but 99.8% were single shots and the repeaters are high $ and i dont reccomend shooting one. There are some guys are cutting 40x single shots for the repeater comversions. There are other custom actions that are 40x footprints and can be built cheap. My Stiller Lonestar was 765$ for the action, screwed a rechambered and cut down factory 40x barrel and a remington trigger that i bedded into a remington wood benchrest stock and did it all for under $1000.
