The Remington Magnum Rimfire .17 HMR in 20-grain is purpose-built for anyone who wants the ballistics of a centerfire without the cost. This round uses a jacketed soft point design that expands reliably on impact while maintaining penetration, making it effective on everything from squirrels and rabbits to prairie dogs and coyotes.
While 17-grain loads dominate the .17 HMR market, the 20-grain projectile offers some real advantages. You get a touch more mass and energy at distance, which helps punch through wind a bit better. At 2375 fps, this load still delivers the flat trajectory the .17 HMR is known for, with minimal drop to 100 yards and under 9 inches of drop at 200 yards. The JSP construction means expansion happens fast on small game while the bullet retains enough integrity to penetrate deeper than a hollow point would. That's the balance that makes this load work across different hunting scenarios.
Remington's standard magnum rimfire line leans on their quality control in both brass and primer selection. You get shot-to-shot consistency that translates to tight groups and reliable cycling, whether you're running a bolt-action rifle or a semi-automatic platform. The ammunition feeds smooth and performs predictably from one box to the next, which matters when you're taking shots beyond 100 yards where precision counts.
The 50-round box format makes it easy to stock up for extended range sessions or a full day of pest control work. It's the kind of ammunition that works equally well for target practice, load development, and actual hunting.
The 20-grain projectile carries slightly more velocity and energy downrange, which can help with wind deflection and penetration on game. You trade minimal velocity for better mass, and some shooters find it performs better at distance. That said, accuracy is always gun-dependent, so it's worth testing in your specific rifle to see which weight group it prefers.
Most shooters consider 200 yards the practical limit, though skilled marksmen regularly connect at 250 yards. The flat trajectory and 2375 fps velocity keep the bullet performing well past 100 yards. Wind becomes the real factor beyond 150 yards, so calm conditions help you stretch the range.
Yes, .17 HMR chambers are available in both rifles and handguns. Rifles will deliver the full 2375 fps velocity, while a handgun barrel will reduce that somewhat. Either way, the round functions reliably and performs consistently across different platforms.
This ammunition is designed specifically for .17 HMR chambers. Do not use it in .17 WSM or .17 HM2 firearms, as it will not function properly. Always verify your firearm's chamber before purchasing ammunition.
