Let’s Talk About Winchester Varmint HV .17 Winchester Super Magnum 20 grain Polymer Tip Rimfire Ammunition S17W20
The Winchester Varmint HV .17 Winchester Super Magnum 20 grain Polymer Tip Rimfire Ammunition S17W20 isn’t just another rimfire round; it’s a game-changer. Marketed as the fastest rimfire cartridge in the world, this ammunition promises to deliver exceptional velocity, energy, and a flatter trajectory, making it a serious contender for varmint and predator hunting. But does it live up to the hype?
My journey to this ammunition started with a persistent problem: wind drift. Years of prairie dog hunting taught me the frustration of watching my .22 LR shots get blown off course by even the slightest breeze. I needed something that could buck the wind better, extend my effective range, and still offer the affordability of rimfire. Enter the .17 WSM. I wanted to see for myself what it could do.
The first thing that struck me upon opening the box was the sleek, spitzer design of the polymer-tipped bullets. Each Winchester round appeared meticulously crafted, the brass cases gleaming, and the polymer tips uniformly seated. It felt like holding miniature, high-performance projectiles. Compared to the standard .22 LR rounds I was used to, these looked downright serious. Other rounds I considered were the .17 HMR and .22 Magnum, but the .17 WSM’s advertised velocity and energy figures were significantly higher, promising the flat trajectory and wind resistance I craved.
My initial excitement was tempered with a healthy dose of skepticism. Could a rimfire cartridge really deliver centerfire-like performance? I couldn’t wait to get to the range and find out. I hoped it lived up to the claims of being the fastest rimfire in the world.
Real-World Testing: Putting Winchester Varmint HV .17 Winchester Super Magnum 20 grain Polymer Tip Rimfire Ammunition S17W20 to the Test
First Use Experience
My first experience with the Winchester Varmint HV .17 Winchester Super Magnum 20 grain Polymer Tip Rimfire Ammunition S17W20 was at my local shooting range, a no-frills outdoor facility with distances out to 200 yards. The weather was typical for a late spring day – sunny with a mild but noticeable crosswind of around 8-10 mph. This was perfect for testing its wind-bucking abilities. Setting up targets at 50, 100, and 200 yards, I prepped my Savage B.Mag rifle, specifically chambered for .17 WSM.
Right away, the difference was noticeable. The report was significantly louder and sharper than a .22 LR. At 100 yards, the Winchester rounds were consistently grouping within an inch, exhibiting minimal drop compared to my .22 LR experiences. The wind drift, while present, was far less pronounced. Even at 200 yards, I was able to maintain respectable groupings, something that was nearly impossible with the .22 LR under similar conditions. There were no immediate issues, and I was impressed by the flat trajectory.
Extended Use & Reliability
After several months and hundreds of rounds, the Winchester Varmint HV .17 Winchester Super Magnum 20 grain Polymer Tip Rimfire Ammunition S17W20 has proven to be remarkably consistent. I’ve used it in varying conditions, from hot and dry summer days to chilly, damp mornings, and the performance has remained reliable. I’ve encountered no misfires or duds, and the accuracy has been consistently good. I found cleaning to be straightforward using standard rimfire cleaning procedures.
Regarding durability, there has been no indication that I should expect anything less than great long-term storage results from this ammunition. Compared to my past experiences with other rimfire rounds, the Winchester .17 WSM clearly outperforms them in terms of velocity, trajectory, and wind resistance. It has instilled a confidence that was previously lacking when engaging smaller targets at longer ranges in windy conditions. The superior performance has made it my go-to choice for varmint hunting.
