This particular air rifle is manufactured by Umarex, and distributed under RWS and Hammerli brands as the 850 or 850 Magnum (no difference beside the nomenclature).
The 850 is a CO2 rifle, and is designed to use "AirSource" type bottles as the reservoir. There are many adaptors available from sources on the internet that will allow one to use standard paintball tanks or remote lines, if desired. There are also instructions for converting an 850 to run on high-pressure air (HPA), as an… Read Full Review

Nice rifle, but the only downfall is the one typical of all co2 weapons....temperature.
When used during the summer, performance is top rate.
Recommend using accupells for best results.
The bolt action is smooth, yet gives a positive feel when loading, and the magazine is easy to insert.
Overall, this is a good performer in both target and field shooting, giving satifying results in both areas.
Will recommend to all to buy one, as the the price is right… Read Full Review

Great rifle. I use Bushnell Legend 5-15x40 scope on it. I get 1 cm groups @ 20 meters with JSB Exact pellets, maybe 1 out of 10 shots goes out of the group. Muzzle speed is amazingly constant.
If you shoot too fast, the CO2 tank chills down and the muzzle speed drops.
The only problem is that you do not know what you run out of CO2 until you observe deteriorated accuracy… Read Full Review

The RWS (Umarex) Model 850 Magnum has good accuracy, Build quality and overall value. I think that this gun is attracting allot of attention. Lots of modifications available and easily bulked or converted to HPA. This gun is pretty amazing. I was blown away with the accuracy of this gun. I can shoot shot for shot with my buddies $1000 + PCP gun. Now he does shoot faster and has more FPE but for targets I am just as accurate. I have converted mine to a 9 oz PB tank and can get almost 400… Read Full Review

I have the .177 version utilizing it for 10 meter target and field shots utilizing the most inexpensive pellets I can obtain (RWS 7.0 Basic) with very consistent and accurate placement.
I have "bulked" the gun, making a quick disconnect adapter from an old AirSource bottle neck and, with a 24 OZ bottle, have (what I feel to be) the most powerful and economical CO2 rifle made.
The consistency (of pressure) and duration of shots that bulking affords helps the accuracy.
I can still unscrew the… Read Full Review

I've been using a single shot .22 cal. Mountain Arms 2250 for about a two years, and while I love the accuracy, I wanted a repeater that wouldn't break the bank.
The RWS 850 Magnum in .22 cal seem to be the only game in town for under $300.
Other than the Logan at $800 and a PCP setup, what's out there?
I bought the gun from Pyramid Air, and the packing and shipping were excellent! This bolt action repeater comes with two 8-round circular clips, and in the month I've had it, this seems… Read Full Review

I was looking for a pellet rifle for pest control and settled on the following criteria: The rifle must be "always ready", powerful, accurate, and capable of reasonably fast follow-up shots. While springers offer the most power for the money, they require an awkward cocking stroke, as well as single pellet loading which I do not find appealing in the field. "Older" eyes don't enjoy futzing around with trying to fit individual pellets into a barrel or chamber without reading glasses, so the… Read Full Review
