I bought my #1-B used and have really come to enjoy it. I have never really worked to nail down the best groups it can do with 40 grain jacketed stuff. However, I rather accidentally discovered a very fine shooting 22 rimfire load for mine. It uses a 55 grain cast GC bullet....unsorted Lyman bullets sized .225, lubed with Rooster HVR softened with a bit of Alox. The powder is Lil'Gun at the volume the Little Dandy measure throws from the #5 rotor, about 5.5 grains +/-. I originally found the load lit with Federal 205 small rifle primers. Looking for possible improvements I tried both the CCI 450 magnum small rifle primer and the Remington 1 1/2 pistol primer. The 450 blows up groups, but the 1 1/2 is probably close to perfect, making 50 yard groups that stay close enough to create one ragged dime-sized hole after a dozen shots, with one or two drifting alone inside a rabbit-head-sized area.
