How to Correct for Parallax — Optics Tip from Nightforce

Nightforce Optics Parallax Newsletter Scope Video

PARALLAX – What is it and Why is it important?

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.

New Savage A22 Magnum For .22 WMR Fans

Savage A22 Magnum A17 auto-loading semi-auto Varmint rifle

The Savage A17 in 17 HMR was American Hunter’s 2016 Rifle of the Year. We weren’t surprised. This little rimfire was the first auto-loader engineered from scratch to handle the pressure of the 17 HMR safely and reliably. The A17 also proved to be very accurate and tons of fun to shoot.

If you like the A17’s award-winning delayed-blowback technology, but prefer to shoot a .22 WMR (Winchester Magnum Rimfire) cartridge, you’re in luck. Savage just announced the A22 Magnum, a new rifle that uses an A17-type action (with innovative interrupter lug), to shoot the .22 WMR cartridge.

The A22 Magnum is chambered for .22 WMR and features the same delayed-blowback auto-loading action as the original A17. The A22 Magnum feature a strong steel receiver, chromed bolt, 10-round rotary magazine, and adjustable Savage AccuTrigger. The A22 employs a thread-in headspace system like Savage’s centerfire rifles. This makes it easier to swap in a match-grade barrel down the line. The A22 also comes with two-piece bases for scope mounts

Advantages of .22 WMR over 17 HMR
We like both rimfire cartridges, but we understand why some shooters may prefer the older .22 WMR over the newer, speedier 17 HMR. Here are some of the advantages of the .22 Winchester Magnum Rimfire (WMR):

Savage A22 Magnum A17 auto-loading semi-auto Varmint rifle1. .22 Caliber bores are easier to clean than .17 caliber bores. Good .22-Cal cleaning rods are less flexy than .17-cal rods and a greater range of jags and brushes are offered for the larger caliber.

2. The .22 WMR makes a bigger hole — this makes your groups easier to see at longer range, and the bigger hole can give you a scoring edge in rimfire competitions.

3. The .22 WMR offers a wider choice of ammo manufacturers and bullet types. If a hunter desires a heavier, non-fragmenting bullet, the .22 WMR may be a better choice.
