RE: Single Six
I received a Single Six for my 16th birthday (I am now 38) and have put thousands of rounds through it. I absolutely love it.
My Single Sixis stainless steel witha 6 1/2 inch bull barrel and the WMR cylinder. It is easily capable of a 2" group out to 50 yards off of a solid rest with good ammo. I regularly shoot it at standard 4 inch clay pigeons set from 7 yards to 50 yards (open sights) with Remington 36 grain HPs in 22LR, and occasionally out to 100 yards (open sights) with CCI 40 grain HPs in 22 WMR.
I have killed a number of squirrels with it.
