TX200 III Spring Buzz

[badger5th]

Did a pellet test for all my current 22 pellets in my TX200 MkIII today. Testing for accuracy and ballistic consistency. Here's the summary:

I noticed that as pellet weight got up into the 18 grain range the spring buzz significantly increased, takes almost 1 second to subside. Is this normal with the TX200?

Might be piston bounce?

Light pellets for caliber will result in piston slam, while heavy pellets for caliber will give you some rebound from the air cushion. I THINK????

Someone who knows stuff will be along to diagnose it for ya man, do not fret.

Yes this sounds right, middle weight pellets are best, you can put some tar on the spring guides and seat to stop the buzz, or buy a Vortek kit, or send it off to Mr. Motor head for the total treatment.

Thats basically how I understand it too. My 57 sounds great with 8.44gr pellets but the second I go over 10gr it sounds like my spring wants to die/snap. You can try adding a bit of weight to the piston via washers/spacers to help power through the bounce but you'll likely have to shorten the guide to allow the gun to cock. Snipping the spring may be necessary to get the power level right as well (or just take the bump) The easiest option is to just stick to pellets weights more appropriate to the power plant like 14-16gr pellets in a .22 TX200.

In looking at the pdf, it seemed to me that the extreme spreads were extreme. Every TX I have owned comes in at 10 or less fps.

I would definitely open it up and check for all the internal parts fitting as they should (not a loose fit) and the seal being perfect, with no cracks, chips, etc. I would also clean up any lube a relube with your lube of choice. I use Krytox, but many others are effective as well.

A quality tune kit could be dropped in as well if OEM parts are not fitting well. In my experience, heavy spring tar is used to compensate for parts not fitting as they should.

Thanks for all your responses. I've just been sitting back reviewing them as they came in. I ordered a Vortek tune kit. I don't expect any issues installing it. Plenty of good videos regarding it.

The Vortek PG4 kit sure made my .177 TX200 a sweet shooter. I just have to make sure I pull it the full extent of the cocking stroke, otherwise it doesn't reset the safety.

Mine came that way from the factory. Vortek kit has been better and hopefully solves the issue as I break it in.

I got my Vortek tune kit this past week. Will install next week some evening and report. Also grabbed a 12 fpe kit for my R9.

I replaced the stock loose fitting steel spring guide with a snug fitting Tinbum delrin plastic spring guide. Presto, no more sprung vibrating on that loose steel guide rod. Installation was relatively simple, even for a newcomer to airguns like me.

Thats not quite what we're talking about in the post you quoted. Sometimes springs aren't powerful enough to push heavier pellets properly and creates issues, primarily piston bounce in that quote.
