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.
