Spring/Piston looking for long term premium Air Rifle

[maverick896us]

I’m sorry, I don’t have an answer for that. I never changed my springs. There are a lot of knowledgeable spring and piston shooters on here though that I would consider to be experts that might be able to answer that. In no particular order and sorry if I miss someone: @Scriv @Hoppalong Doc @Danman @jps2486 @Elexious Musick and several others

Thanks for sharing your experience — it’s interesting that you’ve never had to replace the spring in your rifle. My concern with spring‑piston systems has always been the risk of spring fatigue. I used to believe that after around a thousand shots, the spring would start losing tension and eventually need replacement, which could affect consistency and long‑term performance. That’s why I’ve leaned more toward gas‑ram designs, since they eliminate this issue and tend to hold their power more reliably over time.

If I had to replace the spring every 1000 shots, I'd be replacing the spring every couple of days at best LOL. But. Im not much of a springer now. Years ago I shot a Feinwerbau 300s. It was tack accurate the day I bought and when I sold it a few years later. I never changed the spring. If I was shooting my Diana 48 as much as I shoot the PCPs now, I'd probably have to change the spring at some point. Hopefully the more experienced guys will give you some advice.

The HW 30 and the HW 95 for that cost and smile every trigger pull. I'd probably just do .22 after having the .177 on the 30 and 50
Good luck.

All but one of my springers are in .22 cal.; my next spriinger will be a .22 as well. Orv.

I’ve recently taken some pictures of my Diana 350 Magnum with the NX200 Athena alongside it. The rifle came with an extra piston spring, and I’ve paired it with a Diana ZR mount to stabilize the scope. I’ve also ordered a Hawke 4.5–18×44 AOI scope, which should arrive by Wednesday.

On the ammunition side, I’ve added H&N Baracuda Hunter (0.177, 10.49gr, 400ct), JSB Hades (0.177, 10.34gr, 500ct), and JSB Diabolo Exact Express (0.177, 7.87gr, 500ct) to my collection. I already have Effebi Super Point pellets, but from what I’ve researched, the new selections are far better suited to the Diana 350 in terms of performance, accuracy, range, and destructive power. They should really bring out the rifle’s full potential.

I’d love to hear from fellow shooters — do you agree these pellets bring out the best in the 350 Magnum, or have you found other options that work even better?

Good pellet choices as far as the 10gr ammo,
we have had best accuracy with Jsb 10.03 pellets. You mention you are afraid of spring replacement after 1000 shots or so....i think you may be referring to 'spring set'? All springs do this and it is a normal phenomenon, it should live a long life as long as you don't shoot extremely light pellets all the time.
Overly light pellets are not great for a spring and overly heavy pellets will stress you seals more so.
Over time you will more than likely loose some fps yes, but that should increase your accuracy & make it easier to cock too.
It would be difficult to gauge how long a spring lasts, but with "normal" use (say a few tins/yr) it could well last 5+ years.
Brother had the first gen recoil mount from Diana and it was shifty....the new ones are supposed to be much better!

Today I received my Hawke scope and managed to mount it on a Diana ZR one‑piece recoil‑reducing mount. It took me some time to understand the scope’s functionality and to get the mount properly seated on the rifle’s dovetail. Mounting the ZR was definitely more challenging than expected, and I know it will take me several days to fully zero the scope and get the most out of it.

One thing I’ve noticed: the lower carriage of the ZR mount is firmly clamped to the rail and doesn’t move at all. However, the upper carriage—the part that actually holds the scope—has a very slight side‑to‑side wobble (just a few millimeters) when I gently shake or move the rifle by hand. The scope itself is secure in the rings.

My question is: is this tiny amount of lateral movement normal for the ZR mount’s recoil‑isolation mechanism, or should the upper carriage be completely rigid?
