Back in the 70's I scored a 4" Diamondback for around $300 if I recall correctly. I really wanted the 6" barrel for a longer sight radius, but couldn't find one at the time. Turned out to be an accurate revolver in spite of the shorter barrel.A 22 rf Colt Diamondback was one of those guns on my want list but never happened. Couple of really nice Woodsman's and Hi-Standards but no quality wheel gun.
BIL called me when a groundhog fell into the pit where they dumped corn for augering into their bulk bins. We didn't want to shoot into the metal-lined bin, so he raised the grating and I laid the revolver down and lowered an old plank into the pit. The groundhog seized the chance to escape and scurried up the plank and hit the ground running for the field. I grabbed the revolver, spun around and did two fast DA shots and rolled the little bugger. Although I'll admit here that there may have been some luck involved, my BIL was in awe.
