Spring twang - annoying however worth a tear down to solve ?

[Geoff]

I got the opportunity to shoot all 3 of my 22 cal springers today.  I was looking for best pellet and to be honest was hoping I shot terribly with 2 of them so I could more easily part with them as my collection is TOO LARGE for me.

The last one I shot was my Winchester 850 which looks to be a rebranded Hatsan 95.   The gun had been sitting in the cast for probably 10 months as last time I shot it things went well.

Today when I shot she was twanging like a banjo on me.  It got only slightly better over the 60 or so pellets I tossed checking different pellets.

I would tear it down however this was the last 5 shot group of the night and I find it difficult to tear down a rifle that is shooting well.

What do you do ?  Stop the annoying twang no matter how well it is shooting or deal with it until it starts to shoot terribly.

I loath twangy guns...I'd break it down in a heartbeat. Lots of stuff you can do that really make a difference. I been working on a project and I've all but eliminated the twang.. I ordered a roll of closed cell insulation tape and I'm going to soft bed it. Hoping that makes it even better. Doing a tune shouldn't change accuracy providing you don't nik a seal or mess with the crown.
Good Luck

Get a Vortek kit and problems solved.

Nice Hatty. Pretty rare under the Winchester name as I understand.But I'm guessing you know that. Me, I'd probably live with it for a while with it shooting like that. But as Bill said, a good tune won't hurt the accuracy unless you nick a seal .

[Geoff]

Thank you all.   Winter might be a good time for this task.

I got one Geoff fixed the twang with a guide, really like it same gun as a 95, mine shoots 825s and accurate. David

[Geoff]

I was thinking the same thing David.  My CFX was a twang machine with I got it, and by putting a bit of thickness on the spring guide and top hat shaft it stopped it.

If you know someone who has a lathe, he/she could make you a new tighter fitting sping guide out of delrin. Problem solved.

[Geoff]

Jo - That would be nice, however nobody I know owns one.  I do keep looking at metal lathes then wonder what I would really do with it after making a couple parts.   

Thanks for the suggestion though !

I used this on my Hatsan 1000X/.25:



You can apply it through the slot where the spring is visible without a full tear down. I also sprayed some on the cocking linkage and it now cocks smoothly and there is no more twang. Not a full lube tune, but a quick way to quiet things down and smooth them out. YMMV

 Geoffrey you can use the aluminum ducting tape to build up your spring guide for a twang free fit.

thank you John and Robert

I might try that on my Webley Spector--same as the Hatsan 1000 springer. Does it set up thick? What I mean is where it won't be running off making a mess.
Thanks!

Yes, it sets up like tar. Use masking tape around the slot to prevent overspray, you can use a good solvent like brake or carb cleaner to clean up any overspray. Only downside is that it smells pretty strong for a few days.

John

any idea what it did to your chrony numbers and ES ?

Thanks John-appreciate it. That's what I was hoping for. I'll definitely order some and give it a try!

Didn't do any chrony before & after, just noticed a smoother and quieter shot cycle and smoother cocking.

In my opinion, accuracy like that warrants some extra time and attention to improve the shot cycle. I've promised myself I would put a few tins of pellets down range to let my rifles smooth out on their own, but I inevitably discover them laid out on my workbench getting a home tune or spring kit within a few twangy shooting sessions.
