Frequently Asked Questions

How does .22 WMR perform compared to .22 LR in this revolver?

.22 WMR (Winchester Magnum Rimfire) delivers significantly more velocity and energy than standard .22 LR — typically pushing a 40-grain bullet to around 1,900 fps from a 6-inch barrel. This makes the Model 648 a much more capable option for small-game hunting at moderate distances and for target shooting where a harder-hitting rimfire round is preferred. Note that the Model 648 is chambered exclusively for .22 WMR and cannot safely fire .22 LR ammunition.

Is the Smith & Wesson 648 suitable for competitive target shooting?

Yes — the Model 648 was designed with precision in mind. The 6-inch underlug barrel provides a longer sight radius and reduces muzzle flip, while the fully adjustable rear sight allows you to dial in your point of impact for different loads. The single-action trigger mode offers a crisp, light break ideal for deliberate target work, making this revolver a strong contender in rimfire revolver competition and informal bullseye shooting.

What ammunition should I use with the S&W Model 648?

The Model 648 is chambered specifically for .22 WMR and should only be fed .22 Magnum rimfire cartridges. Popular choices include CCI Maxi-Mag, Hornady Critical Defense .22 Mag, and Winchester Super-X .22 WMR. For hunting, a 40-grain jacketed hollow point is a versatile option for squirrel, rabbit, and other small game. For target practice, full metal jacket or solid loads tend to be more economical while still delivering consistent accuracy.
