17hmr ammo development

Hornady developed the 17 HMR by taking the 22 WMR case and necking it down to accept a .172” diameter bullet. Initial factory loads from Hornady sported a 17 grain Spitzer V-MAX bullet fired at 2,650 fps.

The 22 Winchester Magnum Rimfire (22 WMR or 22 Mag for short) was a natural parent case for the 17 HMR, as it had stronger case walls and offered more case capacity than other rimfire cartridges of the day.

The 17 HMR was nothing short of an overnight success as the round accomplished what wildcatters had been doing for many years, replicating the ballistics of the obsolete 5mm Remington Rimfire Magnum (the fastest rimfire cartridge in history).

Shooters adored the round so much that ammo sales for the new cartridge quickly outstripped production capacity. Thankfully, within 2 years of its release, Remington, CCI, and Federal all began offering their own lines of 17 HMR ammo to help keep up with demand. Today, 17 HMR ammo is also available from Winchester as well.

Although the 17 grain bullets are the most common, alternative loadings with 15.5 grain and 20 grain bullets are also available.

The 17 HMR is typically chambered in lever-action and bolt-action rifles as there were safety concerns about using the round in early semi-auto rifles, many of which were recalled. However, Savage Arms stepped up to the plate and released the Model A17 in 2015 to give 17 HMR fans a semi-automatic rifle that was completely safe to use.

Although the 17 HMR lacks the stopping power offered by the 22 WMR for larger pests, the Hornady round offers hunters approximately a 50% increase in effective range on small varmints like prairie dogs and groundhogs.

On average, the effective range for the 17 HMR against thin-skinned varmints is often cited being around 150 yards. Capable marksmen can extend that range to around 200 yards, but the bullet’s trajectory will suffer as it goes subsonic at 150 yards on average.
