The Howa M1100 Rimfire is a bolt-action rifle chambered in .22 LR. It is sized and weighted for general rimfire use -- 18-inch barrel, 6.3 lbs, 10-round single-stack magazine -- and the H.A.C.T. two-stage trigger is one of the more notable features that sets it apart from entry-level .22 bolt guns.

Features 

 
The 18-inch rifled barrel keeps the package compact while still giving the .22 LR cartridge room to develop velocity. The H.A.C.T. (Howa Advanced Construction Technology) two-stage trigger has a distinct take-up and break, which gives you a clearer sense of when the shot is going to fire than most factory rimfire triggers. The single-stack 10-round magazine feeds reliably with common .22 LR loads. At 6.3 lbs the rifle is easy to carry and steady enough to hold without a rest. 
 

Usage 

 
This rifle fits the target shooting, small game hunting, and new-shooter training roles that most .22 bolt guns fill. The two-stage trigger is an advantage over comparable guns in this price range, and it is worth taking time to learn the two stages before expecting tight groups. Maintenance is straightforward -- .22 LR guns need regular cleaning to keep lead and carbon from accumulating in the bore and action. Customization options exist for optics mounts; the receiver accepts standard rings for scopes.

The M1100 is consistently praised for accuracy, which owners attribute mainly to the H.A.C.T. trigger and the quality of the barrel. The two-stage trigger gets specific mention as a differentiator -- shooters familiar with other rimfire bolt guns notice the improvement. Build quality is described as solid for the price, and long-term reliability comes up positively as well.

Ergonomics draw mixed feedback. Most users find the rifle comfortable, but some note the stock could be more adjustable or better contoured for certain body types. Feed and ejection reliability with different .22 LR brands is generally reported as good, though a few users have preferences for specific ammunition.

Value relative to price is a common positive theme, with the M1100 frequently compared favorably to pricier alternatives. New shooters mention it specifically as a good learning platform given the manageable recoil and the clear trigger feedback. Cleaning requirements are noted as normal for rimfire -- you need to stay on top of it to keep performance consistent.
