The 17 Win Super Mag from Hornady is a fantastic new option for varmint hunters everywhere. Rounding out the Hornady line of high speed rimfire cartridges is the 17 Win Super Mag. Filling the gap between the 17 HMR and the Centrefire 17 Hornet, the 17 Win Super Mag fires a 20 grain V-Max bullet at 3,000 fps.
