The Winchester Varmint HV 17 WSM 20-grain polymer tip ammunition delivers ballistic performance unmatched in the rimfire category. Achieving a velocity of 3,000 feet per second, this caliber exceeds the trajectory, energy retention, and wind-drift characteristics of all competing rimfire cartridges currently available, making it the highest-velocity rimfire product in the world. Each box contains 50 rounds, providing serious varmint hunters and precision shooters with reliable, consistent performance across extended shooting sessions.
The 20-grain polymer-tipped projectile is engineered for rapid energy transfer and explosive terminal performance on small game. At 3,000 feet per second, the 17 WSM generates significantly flatter trajectories than conventional rimfire offerings, reducing holdover corrections at extended range and minimizing the impact of crosswind drift—critical advantages when precision matters. Winchester's ammunition manufacturing standards ensure round-to-round consistency in velocity and powder charge, which translates directly to tighter shot grouping and more predictable point-of-impact shift as distance increases.
This load is purpose-built for varmint control operations and precision rimfire competition. Shooters working prairie dogs, ground squirrels, and other small varmints at ranges where conventional .22 rimfire falls short will find the 17 WSM's superior velocity and energy delivery decisive. The polymer-tip design ensures reliable feeding in 17 WSM bolt-action and semi-automatic rifles while providing performance characteristics that place it in a distinct category above legacy rimfire ammunition. For operators and serious enthusiasts seeking the highest-velocity rimfire solution available, the Win Varmint HV 17 WSM stands as the industry standard.
