RWS Accuracy


January 1, 2014, 06:10 PM
I did the scope mounting and sighting in on my cousins RWS Diana model 48 .
The scope is 4x that came with the rifle and I'm somewhat dissapointed with the groups that I shot from rest yesterday. Any tips/hints would be appreciated as 1&1/2" groups at 50 feet was tops.

What kind of pellets did you use, by chance?

FWIW, air rifles in general can be *very* finicky when it comes to pellets. I had heard this over and over from long time airgunners on the Yellow Forum before I bought. So, when I did buy my RWS34, I bought 6 different kinds of pellets. When I took them to our indoor range (50ft, taking wind out of the equation), I found the results with different pellets varied pretty substantially.

For example, the worst pellets I shot were 2" at 50ft while the best were one .21" hole - and everywhere in between.

Straight Shooters makes a pellet sampler pack (, but I wound up just buying tins of the different ones I wanted to try. I figured that what didn't shoot 'great' could be used for just plinking, knocking sparrows out around the house, or shooting out of the kids' Daisy in the yard.

EDIT: Also! I'm not sure about the Model 48, but the 34 has a couple screws near the front of the neck of the stock that seat the action (just behind where the barrel breaks). Those screws can come loose in transit/while shooting and will definitely throw things off. Check those as well. Mine were loose out of the box...

Spring piston air rifles are notoriously hard on optics. They can shake a good rifle scope apart in a few shots. If the scope came with the rifle, it might be one that is made for the spring piston recoil cycle. Another consideration is the mounting. If the scope mounts to the receiver, there is a chance for small alignment changes each time the barrel is cocked and re closed. Both sights are on the barrel of RWS air rifles for this reason, they stay aligned with the bore no matter how it locks up.
One more thought, try a variety of pellets. Some rifles are picky.

I too have an RWS 48 and can tell you that gun is quite powerful and exhibits a good deal of kick and some vibration.

I shoot at 35 yards from my bench and hold the gun with both hands using an artillery hold, a soft grip that lets the gun make its own moves. I actually make a fist and let the fore-grip rest on it up front. I don't dig my cheek in hard either.

Now for the gun itself. I put a Vortek spring kit and Vortek seals in. When I did, accuracy went way down because it added a substantial amount of power to it. I liked the concept of the spring kit so I took it out and cut about 2 coils off the Vortek spring, flattened and polished the cut end.

That toned it down a bit and accuracy increased tremendously and a good deal of vibration and kick diminished.

I also did some trigger work that made the pull light but not unsafe. That was an important factor in accurate shooting of this gun also.

My gun likes RWS superdome 177 pellets and I use them exclusively.

I am at a point now that I can draw a circle less than the diameter of a quarter and keep most of my shots in it. If I am "on" that day, I often put a group of pellets on top of each other.

Keep in mind, there is a break in period on most air guns that can easily stretch out to 1000 pellets or more.

If you oiled the chamber, you may be experiencing dieseling and that is an accuracy killer too.

Make sure the screws and bolts that couple the action and barrel to the wood stock are tight. Make sure the scope mount and rings are tight.

Last but not least, when the shot finally does break, you should be surprised. If not, you are probably pulling the trigger and that will throw you off as much as anything else.

Thanks for the info guys. My cousin left the rifle with me and I think I'm going to enjoy "getting it to shoot"!

I'd try some heavier pellets, 10gr and good quality like Crosman Premier, JSB, H&N Barracuda. I'd avoid Gamo, Daisy, anything cheap and certainly anything less than 7.9gr. The extra heavy 13.4gr JSB might work the best, plus the weight helps clam the gun a bit.
I had a model 52, same gun nicer stock. It was made in the 80's and quality was poor. My guess is made in china. Point being they varied thru the years so no guarantees it'll be accurate. Best of luck and have fun!

I had a model 52 a few years back.
Same as a 48, just a checkered stock and nicer finish.
But they used to be known for a wondering zero, even with open sights.
Found that the front sight base/sleeve walks forward. then the barrel sleeve comes loose.
I used an epoxy on the barrel sleeve then on the front sight.
