Whew, the Model 61 in .22 Magnum was one of my 'grail' guns for several decades...but I finally gave up on the notion when Magnum ammunition prices went out of sight.
I do have the .22 LR version, and have shot it quite a bit with the issue irons sights as well as a 2.5x Leupold 'Alaskan' 7/8" dia. scope. With that excellent glass mounted, that old 1957 rifle with keep standard velocity CCI's or Wolf Match Target in neat nickel sized 5-shot clusters from the 50 yd line. It's a joy to shoot and generally a toss up with my old Winchester Model 62 with a tang peep as to which one gets to visit the range with family or friends. Hope yours works out as well Best regards, Rod
