Description
Rimfire fans have been asking for a reliable semi-auto in 17 Mach 2 for years, and Savage delivered with the A17 HM2. Instead of stretching a basic blowback design past its limits, Savage built this rifle on the same delayed-blowback action that made the original A17 in 17 HMR work so well. That action is made to handle the higher pressures of the Mach 2 round, so you get clean cycling and quick follow-up shots with a cartridge that pushes a 17 grain bullet around 2,100 feet per second. On prairie dogs, ground squirrels, and pests inside 150 yards, that flat trajectory makes hits feel almost automatic.
What Makes the A17 HM2 Shoot So Well
Accuracy starts with the 20-inch free-floating carbon steel barrel, button rifled with a 1:9 twist that stabilizes the little .17 caliber bullets nicely. Savage's user-adjustable AccuTrigger lets you dial the pull to your liking without a trip to a gunsmith, and it breaks clean enough to get the most out of the barrel. The hard chromed bolt resists corrosion and feeds smoothly, and the case-hardened steel receiver is built to shrug off the extra pressure this cartridge generates. A bolt release and removable dust cover round out the details that make this rifle easy to live with.
A Practical Setup for the Field
The matte black synthetic sporter stock keeps weight down to about 5.55 pounds and won't complain about rain, mud, or a season's worth of truck rides. Sling swivel studs come standard, and the 13.5-inch length of pull fits most adults comfortably. There are no iron sights, which is the right call here since the Mach 2 begs for glass. The receiver comes ready for optic mounting, so plan on adding a scope and getting it zeroed.
Feeding the Savage A17 in 17 HM2
A 10-round detachable rotary magazine sits flush with the stock line and feeds the rimmed cartridge reliably, which flat box magazines often struggle with in rimfires. Loading is quick, capacity is generous for a walk through the fields, and the 10+1 total means you're rarely caught short when a second target pops up.

Frequently Asked Questions
What is the difference between the Savage A17 HM2 and the standard A17 in 17 HMR?
Both rifles use the same proven delayed-blowback action, but this version is chambered in 17 Hornady Mach 2 instead of 17 HMR. The Mach 2 is built on a stretched 22 LR case, so ammo is typically cheaper to shoot, with less report and a trajectory that stays plenty flat out to about 150 yards. The HM2 model also wears a 20-inch barrel rather than the 22-inch tube on most HMR versions.
Does the Savage A17 HM2 come with sights or a scope?
No, this rifle ships without iron sights or an optic. The receiver comes set up for scope mounting, so you'll want to add rings and glass before heading out. Given how flat the 17 Mach 2 shoots, a quality rimfire scope in the 3-9x range is a popular pairing.
Is the AccuTrigger on the A17 adjustable at home?
Yes, Savage's AccuTrigger is designed to be user adjustable without gunsmith work. You can tune the pull weight to your preference using the included instructions, and the integrated blade keeps things safe at lighter settings. It's one of the standout features that separates the A17 from other semi-auto rimfires in its class.
What is the 17 HM2 cartridge best suited for?
The 17 Hornady Mach 2 pushes a 17 grain bullet to around 2,100 feet per second, making it a flat-shooting choice for small game and varmints like squirrels, prairie dogs, and other pests inside 150 yards. It splits the difference between 22 LR and 17 HMR in both performance and ammo cost. Recoil is basically nonexistent, so it's also a fun target round.
