Summary:

I know what a lot of you are saying, why a new rifle cartridge? First let’s get some background on the round.

Nosler, Inc. announced the release of the .22 Nosler at SHOT 2017. The cartridge case is based upon the 6.8 SPC, therefore it mimics the overall length of the .223 Remington but has a fatter case, allowing more powder. The case head is rebated so standard .223/5.56 bolts can be used. The fat case means that 6.8 SPC magazines will feed more reliably than standard AR (5.56) models.

Factory ammunition from Nosler boasts speeds of 300 feet per second faster than factory .223 Remington using comparable bullet weights. The projectiles of .22 Nolser are .224” just like your standard AR.

As you can imagine, Nosler has a good deal of load information for the reloaders in the audience. This cartridge seems ripe for reloader tinkering to come up with the fastest or most accurate load.

The attraction of the .22 Nosler is a super-fast .224 projectile fired from a cartridge that is built for the AR semi-automatic rifle. There are many .224 varmint cartridges that are super fast, but most (if not all) are launched from bolt-action rifles.

When it comes to shooting varmints and predators in the windy western states, most shooters prefer high speed, violently impacting rounds.   

Initial Conclusion:

For this review I used a couple of 6.8 SPC magazines that I ordered from Brownell’s as well a drop-in Timney Trigger for my AR lower, set at 3.5 pounds, from their catalog. Also, the lightweight aluminum rail on the Midway upper did not have a place to secure a bipd so I picked up an Ergo Grips pic rail from Brownells as well. The pic rail took all of five minutes to install.

On paper, as long as I did my part, 3 round shot groups in the 1 M.O.A. to a bit smaller were common at 100 yards. Feeding and function was 100 percent reliable. Yes, I did FrogLube the bolt and carrier group, of course.

In the field I engaged the enemy from 50 to about 300 yards or so. Let me tell you, Chinese acrobats have nothing on the Cynomys Rodentia as they flipped and flew through the air.

My summer-long testing of the .22 Nolser has just begun in earnest, but I am favorably impressed, not just from range time, but from my time in the field.
