I was never impressed with the .22 WRFM until I got my 651.
I never like to be specific about how my guns shoot because whenever I say my gun will shoot such-and-such a group at X range, people seem to come out of the woodwork saying I am a shameless braggart or a terrible shot - sometimes both opinions at the same time.
I learned long ago just not to do that.
But... of my rimfire revolvers, the 651 will shoot with the best of them, and outshoot most. Its the only one I have ever been around, so I don't have much experience with the model, but if my gun is typical of most of them, they are great shooters.
When I was younger and could see better, I was not fond of the sights, but the rest of the gun was great.
