Features 

 
Cold hammer-forging gives the barrel consistent bore dimensions that hold up over high round counts. The adjustable rear sight handles windage and elevation for different .17 HMR loads and distances. The transfer bar is the New Model safety standard. It physically blocks the firing pin unless the trigger is pulled fully, so carrying all six chambers loaded is safe. The single-action mechanism means the hammer must be manually cocked for each shot. 
 

Usage 

 
The .17 HMR is accurate at varmint distances with a flat trajectory, which is where this revolver shines, small game hunting and informal target work at 50-100 yards. The 6.5-inch barrel and adjustable sights let you take advantage of the cartridge's capabilities. Single-action triggers are generally clean and light, which benefits shot placement at range.

Owners appreciate the .17 HMR's flat trajectory and accuracy at varmint distances. The Single Six platform is known for build quality. The cold hammer-forged barrel and Ruger's construction standards draw consistent positive comments. Accuracy at the distances this cartridge is typically used for is frequently highlighted.

The adjustable sights and ergonomic grip get positive mentions, and most users find the revolver comfortable to shoot given the light recoil of the .17 HMR.

The Single Six also accepts a .22 LR cylinder on some configurations, which broadens its usefulness for shooters who want multi-caliber flexibility. Discussions about price are generally balanced. Buyers acknowledge the quality and feel the cost is in line with that. Maintenance is seen as straightforward.
