Don't have a Dan Wesson .22 anymore but they are as or more accurate than any other .22 revolver. And, can be easily made scarily accurate.
The barrel is held in tension the same as the .357's and 44's and that allows the barrel to be "tuned" if you desire by adjusting the torque. Secondly, the B/C gap can be adjusted by turning the barrel in and out, Factory standard was 6 thousandths but I found that 4 thousandths made a huge difference with my gun. Just use an automotive feeler gage and, if you want to get really tricky, use a torque wrench on the barrel. I used to have one of the older Dan Wesson barrel wrenches, the two piece, and used the lug with a socket and a torque wrench. Don't remember how tight I used to set it but it wasn't much.
