    German quality and loaded with features, the Hammerli 850 AirMagnum is so much fun to shoot that you'll have a hard time putting it down.

    Let's start with the all-weather stock. You can take this gun anywhere and not worry about a fragile finish, because it's made from a durable polymer. It's ambidextrous, too, with a raised cheekpiece on both sides of the Monte Carlo stock! This CO2 rifle uses an 88-gram AirSource cartridge, giving you up to 200 shots before you have to change cartridges. The fiber-optic sights will help you acquire your target, but feel free to mount a scope on the 11mm dovetail rail. (Umarex also makes a dovetail-to-Weaver mount; check the Accessories link below.) The checkering on the pistol grip and forearm will help you get a good grip while you plow shot after shot from this 8-shot repeater. This gun is everything you ever hoped for in a CO2 repeater!

    We've recommended some pellets to help you get the most from this airgun. Check out the AMMO link. Remember to click on the ACCESSORIES link to get extra magazines and AirSource cartridges and to select appropriate scopes, mounts and other shooting gear.

    Things I liked:Easy to Load Magazine 88 gram CO2 Cartridge Very Accurate
    Things I would have changed:Having to release the safety each time you cock the rifle. No forward rail for a bipod. You can rig your own which I did.
    What others should know:I'm still going strong on the first CO2 cartridge. About 125 shots so far.

    Things I liked:I have the 177 version of the Hammerli 850 Air Magnum. RWS Super Dome pellets regrouping 0.2 inched center to center at 10 yards.
    Things I would have changed:The 8 shot cylinder does not index well. It works but not smoothly.
    What others should know:DO NOT DOUBLE LOAD PELLETS!!! Make sure you do not double load pellets. I've done this and the weapon fired the 2 pellets. Not a thing you want to do. You could jam things up; If this was a fire arm --- not good! DO NOT SHOOT EMPTY CHAMBERS!!! Know your count (number of shots} If you shoot on empty chamber you can freeze up the valves. Frozen open valve cost you the CO2. If this happens then let the CO2 bleed off and then remove the CO2 cartridge and wait until things warm up. If you rush it you will blow off the reloaded CO2. I have had to wait more than an hour (24 gram of CO2 can really freeze thing up).

    Things I liked:I love this Hammerli 850 Air Magnum .22 caliber pellet rifle. Right out of the box, the accuracy was excellent. From a bench rested position at 10 meters distance, I was hitting the center of three inch targets without making a single adjustment to the fiber optic open sights. Bench rested group sizes were consistently in the range of 5/8" (Crosman Premier Ultra Magnum) to 1" (Beeman H&N Match and H&N Baracuda Match) with the open sights at 10 meters. After mounting a Leapers UTG 4X32 AO rifle scope, the bench rested group sizes were reduced to a range of 1/4" (H&N Field Target Trophy) to 5/8" (RWS Meisterkugeln Rifle and RWS Super Point Extra) at 10 meters. In a standing position at 10 meters with the scope, my group sizes widened to a range of 7/8" (H&N Field Target Trophy) to 1 5/8" (H&N Sport, RWS Superdome, and RWS Super Point Extra).
    Things I would have changed:Nothing
    What others should know:The .22 caliber pellets I have successfully shot with this rifle are RWS Meisterkugeln Rifle, RWS Hobby, H&N Sport, Beeman H&N Match, Crosman Premier Ultra Magnum, RWS Superdome, H&N Field Target Trophy, H&N Baracuda Match, RWS Super Point Extra, and H&N Spitzkugel. Using the 850 Air Magnum CO2 adapter I got a total shot count of 80. Using an Air Venturi 90 g CO2 tank I got a total shot count of 232 before the power became too low.

    • Viktor from USA asked:

      Will You Waste A Lot Of Co2 If You Are Only Going To Shoot About 50 Shots At A Time?

      • Jerry from USA:

        yes because we don t recommend leaving CO2 stored in the gun

    • Jorge from USA asked:

      Can the magazine hold longer pallets like the Baracuda Magnum or JSB Exact Monsters?

      • Dan the Man from USA:


    • Ron from USA asked:

      Ok then how long can you keep the co2 cyl in the gun?

      • Val from USA:

        You can keep it there indefinitely as long as you don't store it in the open area where it has a chance to get too hot. Always use pelgun oil and that will ensure your seals are lubricated and will not dry out.
