The .17 HMR is the flattest-shooting rimfire cartridge commercially available, and it changed what rimfire rifles could do at distance.
A 17 grain polymer-tipped bullet exits at around 2,550 feet per second, giving the .17 HMR a trajectory that is measurably flatter than the .22 LR at all distances past 50 yards. At 150 yards the .17 HMR has dropped less than 4 inches from a 100-yard zero. For prairie dog and ground squirrel shooting at 100 to 175 yards, that trajectory is a genuine capability advantage.
The .17 HMR also brings the same parallax consideration as all rimfire cartridges.
Standard scopes set at 100-yard or 150-yard parallax introduce parallax error at the close to medium rimfire distances where the .17 HMR is used. An adjustable objective scope lets you dial out parallax at the actual shooting distance, which improves precision for a shooter who takes the cartridge’s capability seriously.
Magnification requirements for the .17 HMR are higher than for the .22 LR.
Ground squirrels at 150 yards are small targets. A 9x scope is barely adequate for deliberate shot placement on a squirrel at that distance. A 12x to 16x scope gives the target resolution needed to work confidently at the outer end of .17 HMR range.
These five picks are matched to the .17 HMR’s specific application profile.

1) Vortex Crossfire II 4-12×44 AO – Best Overall
The Crossfire II 4-12×44 AO is the best overall Vortex scope for a .17 HMR because it addresses the parallax issue directly and provides adequate magnification for the cartridge’s target distances. The adjustable objective is the feature that earns this scope the top position.
At 100 to 150 yards, the .17 HMR is at its most useful range for varmint and small game work. Standard scopes set at 100-yard parallax have minimal error at that distance, but a shootable group on a ground squirrel at 150 yards requires every source of error to be controlled. The AO lets you set parallax at the actual shooting distance, removing one variable.
At 12x on a ground squirrel at 125 yards, the target is large enough in the reticle to make a precise head or chest shot call. The 4x low end keeps the scope versatile for field work where shots occasionally happen at close range.
The Dead-Hold BDC reticle can be referenced for informal holdovers at .17 HMR distances. Light recoil from the .17 HMR means zero retention is reliable at this price tier.
This scope is backed by Vortex’s VIP warranty: unconditional, lifetime, and transferable to the next owner.

2) Vortex Diamondback HP 4-16×42 – Best for Extended Range
The Diamondback HP 4-16×42 is the right scope for a .17 HMR shooter who pushes the cartridge to 150 to 200 yards on varmints. At 16x on a prairie dog at 175 yards, the image resolution is sufficient for confident small target identification and shot placement.
The .17 HMR begins to drift noticeably in moderate wind past 150 yards due to its light bullet. At 16x the shooter can see target details clearly enough to identify whether the shot is worth taking given visible wind conditions on surrounding grass or vegetation.
The 4x low end covers the full range of shooting situations on a typical varmint outing. The Dead-Hold BDC reticle provides informal holdover references at .17 HMR distances.
Fully multi-coated glass handles standard varmint hunting conditions adequately. This scope is backed by Vortex’s VIP warranty: unconditional, lifetime, and transferable to the next owner.

Check Price on Amazon3) Vortex Crossfire II 2-7×32 – Best for Small Game Hunting
The Crossfire II 2-7×32 is the right scope for a .17 HMR used primarily for small game hunting rather than deliberate varmint precision shooting. Rabbit and squirrel hunting with a .17 HMR involves shots at varying distances from 15 to 100 yards in field conditions where speed of acquisition matters.
The 2x low end gives a wide field of view for close-range field shots. The 7x upper end is adequate for deliberate 100-yard shots on squirrels and rabbits.
The V-Brite illuminated option adds a visible center dot for low light early morning hunting in dense timber. At 9.9 oz the Crossfire II 2-7×32 is the most compact and lightest option on this list, which suits a .17 HMR hunting rifle that gets carried through the field.

Check Price on AmazonDid You Know? The .17 HMR was introduced in 2002 and became the first new rimfire cartridge to achieve significant commercial success in decades. Hornady developed it by necking down the .22 Magnum case to .17 caliber and loading a 17 grain polymer-tipped bullet at velocities that were genuinely surprising for a rimfire cartridge. The combination of high velocity and the Hornady V-Max bullet design made it an excellent varmint cartridge that exceeded .22 WMR performance at distance while maintaining the rimfire simplicity and low ammunition cost that makes rimfire shooting accessible.
Frequently Asked Questions: Best Vortex Scope for 17 HMR
Does parallax matter on a .17 HMR scope?
Yes, particularly for shooting past 100 yards on small targets.
The .17 HMR is often pushed to 150 to 200 yards for varmint shooting. At those distances, parallax error from a standard 100-yard factory-set scope is minimal but measurable. An adjustable objective like the Crossfire II 4-12×44 AO eliminates that error.
What magnification is best for a .17 HMR scope?
A 4-12x covers the primary varmint range of 50 to 150 yards with adequate resolution. For regular shooting at 150 to 200 yards on small varmints, a 4-16x gives better target resolution for precise placement.
How far can the .17 HMR shoot accurately?
In calm conditions, a quality .17 HMR rifle is capable of consistent small group sizes at 150 yards.
Past 150 yards, the light 17-grain bullet becomes increasingly sensitive to wind. A 10 mph crosswind moves the bullet several inches at 200 yards, which makes small varmint hits unreliable. The practical effective range is 100 to 150 yards for most hunting applications.
Can I use a .22 LR scope on a .17 HMR?
Yes. Any scope suitable for a .22 LR is also suitable for a .17 HMR.
Both cartridges produce very light recoil that will not stress any quality scope. The magnification and parallax considerations for the .17 HMR apply regardless of whether the scope is marketed specifically for .22 LR or general rimfire use.
Is the .17 HMR suitable for squirrel and rabbit hunting?
Yes, but the high velocity and explosive bullet design of the .17 HMR can damage fur and meat on small game at close range.
At 75 to 125 yards, it is an effective and relatively clean small game cartridge. At close range inside 50 yards, the terminal effect can be excessive for meat recovery. Many small game hunters use subsonic .22 LR inside 50 yards and the .17 HMR for longer field shots.
Verdict
The .17 HMR performs best with a scope that matches its practical varmint range and resolves small targets clearly at distance. For a dedicated .17 HMR varmint rifle where precision at 100 to 150 yards matters, the Crossfire II 4-12×44 AO is the right answer.
The adjustable objective eliminates parallax error at rimfire distances and the 12x magnification gives adequate resolution for small varmints at the cartridge’s effective range. For a shooter who pushes to 150 to 200 yards on prairie dogs, the Diamondback HP 4-16×42 gives the 16x magnification needed to resolve small targets at the outer edge of .17 HMR capability.
For small game hunting where field speed matters more than maximum magnification, the Crossfire II 2-7×32 is the compact and light choice. For the best glass quality available in a practical .17 HMR format, the Viper HS 4-16×44 with XD glass delivers image quality above its price class at 16x.
And for a casual .17 HMR build where a simple, reliable scope with the lifetime VIP warranty is the requirement, the Diamondback 3-9×40 covers the practical range at an entry price. The .17 HMR is a capable and specialized rimfire cartridge. Give it a scope that matches what it does well.
