Usage 

At 9.25 lbs., this is a heavy .22 LR. That weight is intentional — the HMR Trainer is meant to replicate the feel of Bergara's centerfire precision rifles so shooters can train fundamentals with cheap .22 LR ammo. The 1-in-16" twist stabilizes standard 40-grain bulk loads well. Ammo sensitivity is typical for .22 LR at this level: it will have preferences, and finding what it shoots best takes some work.

Owners of the Bergara HMR Trainer consistently focus on two things: accuracy and how closely it mirrors the feel of a centerfire precision rifle.

Grouping performance is the main selling point in reviews. Most owners report tight groups at 50 and 100 yards with quality .22 LR ammunition, and several note that the carbon fiber barrel maintains accuracy over longer firing sessions without the usual heat-related drift.

The chassis stock is appreciated for its rigidity and consistent cheek weld. Shooters who train on larger precision platforms note the HMR Trainer translates directly — bolt throw, trigger feel, and stock geometry are close enough that time behind it carries over.

At 9.25 lbs., weight comes up occasionally. It is heavy for a rimfire, which is the point, but some users find it more than they want for casual range days or carrying any distance in the field.

Ammo sensitivity gets a few mentions. As with most accurate .22 LR rifles, the HMR Trainer can be picky about brands and lots. CCI and similar quality loads tend to work well; bulk discount ammunition is less consistent.

The main criticism is limited aftermarket accessory availability compared to more common platforms. Most owners accept this as a trade-off for the precision-oriented design.
