The Bergara HMR Trainer is a bolt-action rimfire rifle chambered in .22 Magnum (22 WMR), built on the same chassis concept as Bergara's centerfire precision lineup. The 18-inch carbon fiber No. 6 barrel keeps weight in check while maintaining rigidity, and the molded mini-chassis stock provides a stable platform at 9.25 lbs. total. Capacity is 10+1.

Detailed Features 

 
The bolt action cycles cleanly with a tight lockup. The adjustable trigger lets you set pull weight to your preference, which is useful for precision work at the range. Quick-detach flush sling mounts are built into the stock for field carry. 
 
The carbon fiber barrel profile reduces weight relative to a steel barrel of the same contour, and the .22 WMR caliber keeps recoil minimal — making extended sessions easy on shooter fatigue. The mini-chassis stock is synthetic and built for outdoor use. 
 

Usage 

 
The HMR Trainer works best as a long-range rimfire practice tool or small-game rifle. The .22 WMR caliber is effective on rabbits and squirrels at reasonable distances. The design mirrors centerfire precision rifles closely enough that it functions as a lower-cost training analog for fundamentals like bolt manipulation, prone position, and long-range hold technique.

The Bergara HMR Trainer in .22 Mag gets consistently positive feedback from shooters using it for rimfire precision practice.

Accuracy out of the box draws the most praise. Owners report solid groups at rimfire distances, and the carbon fiber barrel combined with Bergara's chamber work is generally credited for the consistent performance. The adjustable trigger is a point of appreciation — most shooters set it where they want it and leave it alone.

The .22 WMR caliber is well-regarded for small game and long-range rimfire competition, balancing manageable recoil with meaningful reach compared to standard .22 LR.

Aftermarket accessory options are a mild frustration for some owners who want to customize the platform further — the HMR Trainer is more limited there than Bergara's centerfire chassis rifles. Pricing also comes up in comparisons, as .22 WMR platforms from other manufacturers can undercut it. Most buyers who choose the HMR Trainer are doing so specifically for the Bergara barrel quality and chassis design, and they tend to be satisfied.
