Yes, 5 shot, can be loaded with "Ruger Only" but OAL max is 1.600". Heavy bullet loads must be seated deeper than most load data calls for (with some exceptions) and powder charge reduced accordingly. Bottom gun 4 1/4" has over 25,000 rnds with some of those up to 340gr at chronoed 1,150 fps +-. Not for the beginning reloader if using long heavy bullets. I settled on two loads -- 280 Gr RCBS SWC at 900 fps and 320gr Lee Dual Crimp Flat Nose GC at 1,150 fps the 320 hit 1" higher at 25 yds vs the 280 from the 4 1/4" gun. IIRC the 4 1/4" weighs in at 36 oz and is a great "packin pistor" but a bit frisky with the heavy bullet load. Probably more than anyone wanted to know.
