17 HMR for Prairie Dog Safaris — Effective at Shorter Ranges

Volquartsen 17 HMR Dustin Ellermann 17 HMR

We know our many of our readers enjoy Prairie Dog varminting safaris. For long P-Dog shots you’ll definitely want a centerfire. We like the 20 Practical in an AR and a 22 BR/BRA in a bolt-action. That will have you covered out to 700 yards. But for shorter shots on small critters — say inside 150 yards — it makes sense to have an accurate 17 HMR rimfire rig. Today’s 17 HMRs are capable of surprising accuracy, rivaling a good centerfire rig, but with way less recoil and much lower cost per shot. And the 17 HMR offers more than double the velocity of a .22 LR — up to 2650 fps with a 17-grain bullet.

Top Shot former Champion Dustin Ellerman likes his Volquartsens, and we can see why. With one of his favorite 17 HMR rimfire varmint rigs, he’s seen some outstanding accuracy with CCI ammo. A few seasons back, on his Facebook page, Dustin reported: “Prepping for prairie dogs and I’m floored by this cold, sub-half-inch group shot with the Volquartsen Custom 17 HMR at 100 yards.” This thumbhole-stock rifle features a Bowers Group USS suppressor, and 3-12x56mm Meopta Scope. Dustin tried different types of CCI 17 HMR ammo. This small group was shot with CCI A17 ammo.

What’s the effective range of a 17 HMR on prairie dogs? You might be surprised. in 2015, Dustin took another Volquartsen 17 HMR on a Prairie Dog hunt in Wyoming. He was impressed with the rifle (shown below) and the little rimfire cartridge. Dustin says the effective range of the 17 HMR is farther than one might expect: “I made hits out to 300 yards. 200 yards was easy as long as the wind wasn’t too bad.”

Here’s the Volquartsen 17 HMR Dustin used in Wyoming in 2015:

After that 2015 P-Dog expedition, Dustin became a fan of the 17 HMR cartridge: “Never paid it much attention before now because the ammo is five times more expensive than .22 LR and I mostly target shoot. However, for prairie dogs, the 17 HMR is amazing!” Consider this — Hornady’s 17 HMR ammo pushes a 17gr V-Max bullet at 2550 fps, twice as fast as typical .22 LR rounds.

Eliminating Parallax Errors — Nightforce Optics Tech Tip

Nightforce Optics Parallax Newsletter Scope Video
Nightforce Optics Parallax Newsletter Scope Video

PARALLAX – What is it and Why is it important?

Nightforce Optics Parallax Newsletter Scope Video

What is Parallax?
Parallax is the apparent movement of the scope’s reticle (cross-hairs) in relation to the target as the shooter moves his eye across the exit pupil of the riflescope. This is caused by the target and the reticle being located in different focal planes.

Why is it Important?
The greater the distance to the target and magnification of the optic, the greater the parallax error becomes. Especially at longer distances, significant sighting error can result if parallax is not removed.

How to Remove Parallax
This Nightforce Tech Tip video quickly shows how to remove parallax on your riflescope.

While keeping the rifle still and looking through the riflescope, a slight nod of the head up and down will quickly determine if parallax is present. To remove parallax, start with the adjustment mechanism on infinity and rotate until the reticle remains stationary in relation to the target regardless of head movement. If parallax has been eliminated, the reticle will remain stationary in relation to the target regardless of eye placement behind the optic.

This Parallax Discussion first appeared in the Nightforce Newsletter. Nightforce also offers a series of Informational Videos covering a variety of topics.

Ammo Encyclopedia 7th Ed. — Over 300 Cartridge Illustrations

Brussard ammunition encyclopedia 7th Edition

Wouldn’t it be nice to have a print resource that has hundreds of true-size cartridge illustrations, plus technical descriptions of thousands of popular cartridge types? That could be a real time-saver. It’s no wonder this Ammo Encyclopedia book is an Amazon category best-seller.

If you’re a serious shooter, the latest 7th Edition of the Ammo Encyclopedia belongs in your library. This 928-page book by Charles Priore Jr. and Lisa Buening is probably the most comprehensive and up-to-date book in print covering current and classic cartridges and shotshells. The Ammo Encyclopedia is a massive resource work. The 7th Edition, released in October 2022, now boasts 100+ chapters, covering thousands of handgun, rifle, and shotgun cartridges. This 928-page softcover book sells for $44.42 on Amazon.

One of the best features is a full-color section depicting actual size drawings of over 300 current rimfire/centerfire cartridges and shotshells. You won’t find that many “life-size” cartridge drawings in one place even on the internet. Cartridge profiles and ballistic charts have been expanded to include many new factory cartridges. An expanded Trademark Index lists contact information for all current ammunition manufacturers.

For the 7th Edition, over 150 cartridge types have been added. And dozens of previously proprietary cartridges now have individual profiles. An expanded color section shows current centerfire, rimfire, and shotshell cartridges in full color. Plus updated Ballistic Tables provide muzzle velocity, dimensions, and page numbers for the corresponding cartridge profile pages.
