Cci Maxi-mag 22 Wmr Hp 40 Grain Review

If you are new to 22 WMR, I'll endeavour to eliminate some potential defoliation that I experienced when I expanded my rimfire horizons across 22 Long Rifle.  The 22 WMR name is ammo shorthand for .22 Winchester Magnum Rimfire.  You may also see the same cartridge called 22 Mag, 22 Magnum, 22 Win Mag, or some other variation that doesn't pop into my caput right at this moment.  Regardless of the name, the 22 WMR is a wicked rimfire round that delivers exceptional terminal performance for hunting minor game and varmints at ranges to 100 yards and beyond.

The CCI catalog lists vi 22 WMR loads classified as varmint loads.  The chief deviation betwixt a varmint and pocket-sized game load is what happens to the bullet when information technology strikes the intended target.  Varmint bullets are designed to expand violently, fragment, and dump their kinetic energy into the target as apace as possible.  Sometimes with explosive results.  Small game bullets are designed for limited expansion to minimize harm to the meat of the game animal, while penetrating deeply for a humane harvest.

It is possible to use varmint loads for small game hunting, just every bit it'due south physically possible to hunt ducks with a 30-30, simply you may not like the condition of your quarry when you remember it.  You volition exist much amend off using a small game load on a varmint, than using a varmint load on small game.  CCI simplifies the ammunition selection process a fleck by classifying the Maxi-Max as suitable for varmint and modest game.

These two CCI 22 WMR loads are, in my opinion, those you will nigh likely find available if you lot buy your ammunition at a large national retail chain.  For this reason, I idea information technology best to start my 22 WMR testing with these loads.  Initially, I planned to report on each load individually.  After running the tests, I changed my mind because these two loads perfectly illustrated the terminal performance differences between small game and varmint loads.

Exam Protocol

5 examination shots for accuracy and velocity.  Measured at 40 yards.

Multiple test shots into a block of Clear Ballistics gel placed 40 yards down range. Test shot velocity is measured at the gel cake.

Recovered bullets are weighed and measured with averages recorded in the data canvass beneath.

40 1000 accuracy was a scrap over half an inch for both loads.

Examination Recap

Velocity - both loads ran slightly faster than the specification from CCI.  Our velocity measured at 40 yards was almost every bit fast as the 25 yard velocity published by CCI.
Maxi-Mag average velocity 1643 fps
Maxi-Magazine +5 boilerplate velocity 1962 fps

Accuracy - both loads were reasonably authentic in the test burglarize.  While a total l yard test would accept been better, the range was too muddy beyond the 40 g line on exam mean solar day. With the burglarize zeroed for the Maxi-Mag, information technology was interesting to see the point of touch alter by iii/iv of an inch with the lighter Maxi-Mag +V.
Maxi-Mag 5 shot grouping size .608"
Maxi-Mag +V 5 shot grouping size .629"

Retained Weight - The Maxi-Magazine +Five travels faster because it is 10 grains lighter than the Maxi-Mag. Both bullets demonstrated significant fragmentation, which is to be expected with a varmint bullet. Equally y'all look at the recovered bullets the Maxi-Mags are perfectly formed mushrooms and the Maxi-Mag +V bullets have completely turned themselves inside out.
Maxi-Mag average retained weight 31.half-dozen grains  79% weight retention.
Maxi-Magazine +V average retained weight xviii.7 grains  62% weight retentivity.

Penetration - If there was a surprise hidden in this test, information technology was the large variation in penetration between the 2 loads.  The average penetration of the Maxi-Mag was more than double that of the Maxi-Mag +V.  On the surface it would be like shooting fish in a barrel to explain away the difference past looking at the expanded diameter differences between the 2 loads, but that'south only function of the reason.  The sectional density differences between the two bullets as well played a office in the penetration variation.  If yous want to go your ballistics geek on, here's a neat primer on sectional density from Chuck Hawks.  Substitute

, and you will see that the article applies quite well to this examination.
Maxi-Mag average penetration fifteen.3 inches.
Maxi-Magazine +V average penetration half dozen.89 inches.

Expansion - The Maxi-Mag +V bullets didn't just expand.  They blew up and turned themselves inside out.  The recovered bullets are apartment discs of lead clinging to a sheet of copper bullet jacket.  The Maxi-Mag bullets have a traditional bullet profile with a bullet shank capped by a flattened and expanded olfactory organ.
Maxi-Mag average expansion .328 inches.
Maxi-Mag +V average expansion .396 inches.

In a perfect world, both of these loads would be readily available and you could continue a supply of each on hand for any type of hunting yous were planning on doing.  If I had to selection one load, due to current ammunition availability issues, I would exist totally satisfied with the Maxi-Mag for pocket-sized game hunting and varmint hunting/control.  In this test it was slightly more than accurate, expanded well, and penetrated to a sufficient depth for small game hunting.
