This may be the only new cartridge at the 2013 SHOT Show. Winchester’s new 17 caliber rim fire is an attempt to capitalize on the success of the 17 HMR. I will be challenged on that point, so lets try and answer that challenge right here. The 17 HMR has had reasonable success because it was intended to put 17 caliber cartridges in the hands of shooters without the need to reload.
Obviously there are some center-fire cartridges in the marketplace that address these shooters as well. The 17 Remington Fireball and the 17 Remington are substantially bigger cartridges. Being center-fire generally means more expensive firearms too.
The advantage of rimfire is lower cost ammunition and lower cost firearms as well. The only two models chambered for the new Winchester Super Magnum at SHOT Show in 2013 was one rifle from Savage Arms, and the model 1885 low wall from Winchester.
Winchester lists three loads for the new rim-fire cartridge.
- S17W20, Polymer Tip, 20 gr. bullet, 3000 fps
- S17W25, Polymer Tip, 25 gr. bullet, 2600 fps
- X17W20, JHP, 20 gr. bullet, 3000 fps
At about 600 fps faster than the HMR the 17 WSM has a about half the drop with the same bullet weight. For more information see: http://winchesterproductdemos.winchester.com/17WinchesterSuperMagnum.html#/Home
