Last Updated on

Umarex may be the new name but the old title of Hammerli remains just as popular. This air rifle was introduced as a high power CO2 option for game hunters! The name situation makes things a bit hard to follow, but know this – The Hammerli 850 goes under the name Umarex in the US market. They’re one and the same.

German company Umarex are experts at CO2 power, and they introduced the world to the first mass-produced, affordable and full-power 12 ft/lb CO2 hunting rifle, the Hammerli 850 AirMagnum. It is powered by liquid gas, and made up of synthetic material, making it light in weight and economical. The Hammerli 850 AirMagnum has been the solution for those seeking an accurate rifle with a real firearm feel but cannot afford the real deal.

Hammerli / RWS are well known for standing behind their guns, whatever they claim, and they do deliver! Their warranty has always been the best in the market. Therefore, Umarex Hammerli 850 is another trusted name in the community.

The Hammerli 850 AirMagnum is popular with pest controllers in particular. The rifle comes with smooth blacked-steel cocking and a generous bolt.

It’s a lot of fun to shoot with, so you will have a hard time putting it down. The Hammerli 850 AirMagnum‘s stock is synthetic though, known as an all-weather stock. You can take the gun anywhere and not be worried about the finish as it is made of durable polymer with a Monte Carlo stock!

The Hammerli 850 AirMagnum uses 88 gram air source cartridge, which allows you to have 200 – 250 shots before you need to change the cartridge.

The rifle comes with a fiber-optic sight to help you acquire your target. You can feel free to mount a scope on the 11mm dovetail rail. Based on the German quality, Umarex makes a dovetail–to-weaver mount.

Cocking Effort And Trigger

You should think seriously and consciously about the trigger performance or the cocking ability – you don’t want something that fires off course too easily.

Luckily, the trigger performance of the Hammerli 850 AirMagnum air rifle is just unbeatable. The HAM team has taken the test to check the ability of the trigger, and the results are amazing. The Hammerli 850 has a cock-on-opening bolt-action, and it’s,m a. And for sure, it is actually very easy to manage. This means that the Hammerli 850 is suitable for both young shooters or less physically strong adults.

The rifle does not discharge accidentally even with the lower pull weight of just 1 lb. Therefore, the Hammerli 850 AirMagnum air rifle is safe to use in any way. Moreover, the trigger pull is very smooth and consistent. But I would make it clear here that if one snatches the rifle during shooting, it will miss the second target.

You would be amazed to learn that the Hammerli 850 has a bolt action that works like a firearm; this is the big attraction for you towards the rifle. If you have a military background or interest in real firearms, you would love to have Hammerli 850 in your collection.

Note that the bolt is a little bit rough and bulky as you close the stroke. But, maybe with time as you use the rifle, it’ll become smoother. There is nothing wrong with having an action like this — it’s just something you’ll get used to.

Stock

The Hammerli 850 AirMagnum wood stock is synthetic. Umarex has made the gun to be used anytime, in any weather, and it’s beautiful in black – reminiscent of the military.

The Hammerli 850 has that renowned German quality as it is made of durable polymer. With a raised cheek-piece on both sides of the Monte Carlo Stock, it is ambidextrous. The rifle has an air-source cartridge of 88gms. It is quite useful because it allows you to have up to 200 or 250 continuous shots before you change the cartridge.

Scope And Sight

The Hammerli 850 AirMagnum comes with fiber optic sights, which are very popular in airguns nowadays.

These sights allow you to adjust between to a bright red, hooded foresight which is nicely designed along with an adjustable rear sight. You can also add green fiber optics on a sliding ramp — all you need is a screwdriver to make the change.

Price

The Hammerli 850 AirMagnum costs between $250 and $280. Being a CO2 air-rifle, this is a viable alternative for the shooters or hunters who are looking for a PCP rifle with minimal recoil and don’t want to buy a refill tank.

If you compare the accuracy and reliability, and indeed the real firearm feel, none can beat the Hammerli 850 AirMagnum at such a low price. All the tests conducted by HAM are very satisfactory indeed.

The Hammerli 850 AirMagnum fulfills every primary requirement of the shooters. If you are looking for a magazine-fed bolt action rifle, with accuracy and ease of use, Hammerli 850 AirMagnum suits you down to the ground.

Accuracy And Speed

Your concern regarding the accuracy has been very much considered by the Umarex Hammerli AirMagnum 850. The speed of a CO2 air rifle can never be compared with a real gun because it cannot fulfill the requirement of a minimum number of shots per fill.

You can consider the multi-shot capability and lack of recoil at a reasonable price with simple appearance and features.

The HAM team has tested the Umarex Hammerli AirMagnum 850 at a temperature of 65 degrees Fahrenheit. Below are the results:

Gamo Raptor Platinum 9.7 Grain674 fps9.8 ft/lbsGOOD

H&N field target trophy 14.66 grain609 fps12.1 ft/lbsEXCELLENT
H&N Barracuda match 21.14 grain519 fps12.6 ft/lbsGOOD ONE FLYER

The muzzle velocity is quite a complicated topic when it comes to CO2 powered air guns since CO2 is performance is so dependent on temperature. As the temperature rises, so too does the pressure of the CO2. As the CO2 increases, the muzzle velocity increases as well since the temperature increases by 2 degrees Fahrenheit.

PelletMuzzle Velocity calculated at 67F-AverageMuzzle Velocity calculated at 75 F-AverageMuzzle Velocity calculated at 90F- Average
Gamo Raptor Platinum 9.7 Grain674 fps690 fps720 fps
H & N field target trophy green 14.66 grain668 fps684 fps714 fps
RWS hobby 11.9 grain640 fps656 fps686 fps

H&N field target trophy 14.66 grain609 fps625 fps655 fps
H&N barracuda match 21.14 grain519 fps535 fps565 fps

The table, as mentioned earlier, clearly shows the result of the increased muzzle velocity with an increase in temperature. But the growth is limited; it cannot be said that it would grow at infinity. At around 95 degrees Fahrenheit, there is an increased pressure in the “valve lock”, and the muzzle velocity begins to fall very quickly. Therefore, it is accurate to say that around 90 degrees Fahrenheit is the maximum shooting temperature for CO2 powered air rifles.

Manufacturers recommend that if you do this and your valve lock gets heated, then allow it to cool down. This will bring the pressure down and allow you to shoot again.

JSB Jumbo Exact Pellets achieved the best accuracy with the Hammerli 850. However, this air rifle is not picky about pellets and shows good accuracy with a whole range.

Consistency

The Umarex Hammerli 850 AirMagnum demonstrates good consistency all around. The standard deviation dropped to a lower extent of 4.2 FPS with JSB jumbo pellets.

With GAMO platinum PBA pellets, the standard deviation recorded by the Hammerli 850 AirMagnum air rifle was just 8.7 FPS. This was its best performance.

The weight of the trigger pull was rock-steady, with no such variations when tested by HAM. This is outstanding and quite rare!

Loudness

The Hammerli 850 AirMagnum air rifle is a high powered CO2 air rifle with no silencer. However, this is not the disappointment it might seem as many shooters like the noise! It’s worth noting that the HAM team expected the sound to be much louder because it is high power CO2, so the noise still doesn’t meet the norm for this type of gun.

You cannot compare the Hammerli 850 AirMagnum air rifle with .22 LR firearms in terms of noise of course – it’s much quieter, even in .177 caliber. Even Paul Capello confirms that Hammerli 850’s level of noise is okay for the backyard shooters:

Shooting Ability

Amazing results here for Hammerli 850 AirMagnum air rifle! The Hammerli 850 AirMagnum air rifle is so perfect. It is easy to shoot as there is not such heavy cocking and no recoil. It doesn’t take at all long to master.

he rate-a-gun score is 4.1, which is outstanding. The Hammerli 850 AirMagnum air rifle is very easy to handle and quick on the target. The 16 joules valve is best for shooting with accuracy. Let’s take a look at other air rifle of Umarex, Umarex Octane Review.

You can load the clip of the Hammerli 850 XT very smoothly, but it is suggested for you to take some time to push every pellet right down to the hole so that the compressed pellet is seated correctly by the O ring that runs around the clip.

The HAM team experienced no misleads during the examination of the Hammerli 850 AirMagnum air rifle.
