RWS 350 Magnum-What you think about it?

I have one. If you are going for dime sized groups at any range beyond 20 yards or so you probably should pass it up. That said, I really like mine and it is a .177. It shoots Kodiak and Baracudas at 930 fps and holds 3 or 4 MOA, maybe a bit better if the stars align properly. It is a hunting rifle and stones squirrels out to about 40 yards or so although I did get lucky on one a bit past that this year.

If you are looking at springers and like RWS, look real hard at that 340 in .177. I'll bet that is one nice shooting general purpose rifle.
 
I'm happy with my 350. As above it's not a dime size grouping gun. Plenty of squirrel killin power though and usually gets the shot within minute of squirrel. It is so much about the hold. You have to experiment with these big springers and find just how they like to be held and then weld that into your brain. Permanently, cause the rifle knows what it wants and it will not compromise. They're also not backyard friendly. I don't care as I live in the country. The 350 is pretty heavy. Walkin around with one will get you some exercise.
 
The RWS 350 Magnum is a good looking well made rifle. It is Loud...It is heavy to cock and takes a lot of practice to be accurate beyond 30 yards. I say practice with the artillery hold and use a heavy pellet if shooting 177. I use the JSB Exact Beast (16.2) to slow the rifle down and get any kind of consistency. It will eat scopes...you must put a scope designed for heavy springer rifles for any longevity. I believe it takes about 35 lbs of force to cock, so shooting sessions will make you like Popeye or wear you out working through a tin of pellets. It can be shot with consistent results if you stick with it and find your best hold on the forward position of the stock. A very powerful rifle even in 177. I keep it to remind me why I went to PCP air rifles and as I said earlier it is a nice looking rifle of very good material and build. It is one of those Legacy hand me down sort of rifles not for the timid and definitely not back yard friendly...I hope that helps with your decision to purchase and own.
