17 WSM – 20 Gr Polymer Tip – Winchester Varmint HV (S17W20) – 500 Rounds

This 17 WSM load (S17W20) gives small-game hunters serious rimfire speed with a flat trajectory and explosive terminal performance. Winchester loads it with a 20 grain polymer tip bullet. The polymer tip improves aerodynamics. It also helps drive fast expansion after impact. As a result, this round hits small targets with speed, precision, and sharp energy transfer.

Winchester rates this load at 3,000 fps and 400 ft-lbs of muzzle energy. Therefore, it outruns traditional rimfire cartridges by a wide margin. The 17 WSM gives hunters more reach than 17 HMR. It also carries more energy downrange. That matters when shots stretch across open fields, fence lines, orchards, or prairie dog towns.

The 20 grain bullet gives this load a useful balance. It stays light enough to move extremely fast. Meanwhile, it carries enough weight to hit harder than many smaller rimfire bullets. The polymer tip makes the bullet open quickly on varmints and small game. Consequently, this load works well for prairie dogs, ground squirrels, rabbits, crows, and similar targets.

Recoil stays very light. However, the cartridge delivers centerfire-like speed from a rimfire platform. That combination makes it easy to spot impacts and correct quickly. Moreover, the flat trajectory reduces guesswork at varied distances. Shooters can hold more confidently and spend less time compensating for steep bullet drop.

Each box contains 50 rounds. Each case includes 10 boxes, totaling 500 rounds. That quantity suits regular field use and high-volume varmint shooting. Winchester uses brass rimfire cases, so the ammunition is not reloadable.

This is a fast, sharp, purpose-built 17 WSM hunting load. It gives shooters speed, reach, explosive expansion, and enough volume to keep a varmint rifle working through long days in the field.
