In 30 years I have owned and shot the hound out of six M-18. I had one that would not shoot under 2 inches. It came very close... but it never quite made the cut. The other five all would shoot under 2 inches firing 12 shot groups, i.e., twice around the cylinder, from a hand-held sandbag rest. Back around 2002 I bought a lightly used 18-3 from an acquaintance. Using plain bulk packed Remington Thunderbolt .22 LR ammo, it will put the above mentioned 12 rounds into about 1 1/2 inches at 25 yds. firing without a sandbag, etc. but simply resting my hands on the roof of the car. This past week I spent an afternoon shooting it at the range. Shooting single-action from a standing two-hand hold, I put six shots into 1 3/4 inches. I was shooting at a worn harrow blade that I had painted white. I was aiming at the axle hole. This same pistol fired from a standing two-hand hold at 65 long steps has produced groups of 5 inches using CCI Mini-Mag .22 LR ammo. When my daughters were little, we would collect the large pine cones to make Christmas decorations. I could shoot the pine cones out of the large pine tree in our back yard. I've had a number of Model 17's, and they are fine range revolvers. But in my opinion the Model 18 is the preeminent .22 LR revolver.
