They're a nine grain pellet that really seems to have good accuracy in the 46. Underpowered rifle for this weight pellet you say? I haven't seen any damage as yet though it could happen. Then I'll just pick up a Maccari spring or two and move on. These parts are easily replaceable in the newest era Diana airguns. If its a matter of accuracy, consider the knockdown power of these pellets at your shorter ranges.
Too cold to test them at the longer ranges here in central Minnesocold just yet lol.
My Diana 46 seems to like them very well so far. Let's see what that means to the longevity of the factory spring...
I'm using these pellets in my RWS 34 panther when I'm shooting on paper targets. They have good accuracy, even at 50 meters. But for hitting cans and hunting, domed pellets are more powerfull (RWS superdome, H & N barracuda...)
I think it's a good choice for a mid power airgun like a RWS 34. The weight of these pellets is good for the spring, you don't think so ?
In my RWS 52, they have less accuracy after 35 meters, I'm using H&N barracuda (0,67 grammes) and I will try Diana High Power and Weihrauch Magnum soon (I ordered several sorts of pellets in Germany, they have much more choice than in France !)
