I'm sorry I let a buddy talk me out of my target Buckmark but he shot way better then I did. I shoot my best with a 999 Sportsman and can keep up with the Buckmark. The Browning was a beautiful pistol but I just shoot revolvers better. I don't know if all H&R's shoot this well or I just got lucky.
I think it all depends.
In the early 1970's I had a Browning Nomad. It was a nice accurate .22 semi auto with a very good trigger. In theory, the semi auto should be more accurate than a reviver because the one chamber integral with the barrel. And I could shoot the nomad well.
But...for whatever reason, I could shoot the Smith and Wesson model 18 revolver better. Why? I haven't a clue. Did it fit my hand better? Did I just like it better? Maybe a yes on both counts. Those old 999 Sportsman were exquisite gems of a revolver, with a feel in hand and balance that was just great. I have a friend that has one, and once a while he lets me shoot it on a range trip. Great gun!!!!
Most likely a combination of how it feels in your hand, balance of the gun, and just pure love for it, you shoot it better. For whatever reason, it works better for you.
I have a H&R 686 which shoots well but not as good as my Ruger MKII or B-I-L's S&W 17. But, for the buck it shoots very well. Trigger is good but not great. For me I think the sights are more of the problem than the inherent accuracy of that revolver.
The list is good if allowed several other good guns have been mentioned and I would add the Dan Wesson 22 revolver it was a tack driver. The most accurate I have shot out the box was a Ruger mk2 govt target. But others were very close. The past had some really great guns no doubt but today's guns are good also.
The older I get the more I like the 22 lr pistol or revolver.
