Features: 

The fluted heavy target barrel helps manage heat during extended sessions and improves stiffness for consistent accuracy. The delayed-blowback action is designed specifically for the .17 WSM cartridge's higher pressure compared to standard rimfire rounds. The hard chrome bolt with oversized handle cycles quickly and holds up to rough conditions. Savage's AccuTrigger is user-adjustable without a gunsmith. You can set the pull weight to your preference within a safe range. The thumbhole laminate stock gives a stable grip position that most shooters find comfortable for bench or field use. 
 
.17 WSM hits harder than .17 HMR at distance, with a flat trajectory and minimal wind drift, useful for varmint work or informal long-range rimfire shooting. 
 

Usage: 

• Small game and varmint hunting 
• Competitive rimfire shooting 
• Range practice

The Savage A17 WSM Thumbhole draws consistent praise for accuracy and the AccuTrigger, with some recurring concerns about reliability and ammo sensitivity.

Accuracy is the most common positive. The .17 WSM cartridge shoots flat and the fluted barrel keeps groups tight. Owners doing varmint work or informal long-range rimfire shooting report good results. The AccuTrigger gets credit for being adjustable and predictably crisp. The thumbhole laminate stock is appreciated by most for its ergonomics, though some prefer a traditional stock profile.

The main issue that surfaces is ammo sensitivity. The delayed-blowback action needs cleaner-burning, higher-quality ammunition to cycle reliably; some owners report feed or extraction hiccups with certain brands. .17 WSM ammo selection is narrower than .22 LR or even .17 HMR, so this is worth factoring in before buying. Weight at 7.1 lbs is noted occasionally, not heavy for a bench gun, but heavier than expected for some field use.

Price is generally seen as fair for the feature set. Overall, buyers who understand the ammo requirements going in tend to be satisfied; those who expect .22 LR-level reliability with any bulk ammo sometimes aren't.
