Air Arms too heavy

No.
The heavy pellets will take a few more micro-seconds in the barrel and may at the closer ranges shoot a bit high because of the barrel dwell time and will be considerably slower than what you are using now.
For a bunch of years, the ill informed used to preach the lie about heavy pellets hurting the spring.
In the case of your TX…the spring used in the .177 and the .22 is the same.
You cannot damage your rifle by shooting heavy pellets .
In reality, you could cause more damage by shooting light (Light for caliber) pellets.
I would not shoot light alloy pellets in your TX… or…my three.😂

I guess a gun /spring can just give of up anytime regardless of pellet weight .. good fit in the leade / barrel i think is key over anything else .. still any spring could last 1 shot or 10,000 . Man ive had some short lived ones ..lol

I have read several articles stating that using to heavy of a pellet in a springer will damage it ? I have a TX200 factory tune . i have been shooting pellets in the 8.4 to 10 .7 range for a few years , just wonder if it would hurt the gun to shoot 15 or 18 GR pellets , .177 "rabbit Magnum :

I would think it's the inverse. Heavy pellet has long bore time, more force for the piston to push against and slow down with before bottoming in the tube. I would think the gimmick gold pellets or felt cleaning pellets would be more likely to hurt a springer.

Just my thoughts, nothing more than "trust me bro" science.

TX's use very minimal spring preload, as such shooting an overly heavy pellet will likely create piston bounce as the compression of air and required energy to get a heavy pellet into motion will have piston likely bouncing / rebounding off this compression spike during the pellets launch time.

You will feel it become weird in the cyclic action when discharged feeling non typical.

I tried heavy pellets in my spring guns with poor results . I used to shoor a lot of 22-250 and hand loaded everything. I tried heavy bullets over 55 grains and they would group terribly. I tried a 70 grain bullet and it hit the target sideways. the rifle couldn't spin the bullet enough to stabilize it. 50 -52 grains 1/2 in groups all day at 100 yards. I’m assuming Airguns barrels are designed a similar way. with a twist rate that will accommodate a certain range of weighted pellets. (I’m guessing here) 7.0-10.5 range. I’m not sure what thw twist rate is but you can figure it out yourself.
just my thoughts

I use to have a tx 200 hc in 177 and it only liked heavy pellets like, if I recall correctly, crossman premier heavies. Those were the most accurate in my gun. It did not like the lites at 7.9 grains for some reason. I figured back then that if the springs life was going to suffer an early death, I would just replace it. These are the easiest guns to replace internals.

Hate to tell you guys. Heavy pellets do shorten spring life. How much might not be enough to matter. Heavy pellets as Motorhead said often induce more piston bounce. The abrupt change of direction is tough on springs. How much it hurts varies spring to spring as there's lots of factors. Factors like preload and material come in to play. It's just not heavy pellets that cause this. Tight fitting pellets can have the same effect. Tight pellets increase start pressure or back pressure the same way heavy pellets do.

An easy way to tell if you're potentially hurting the spring is look at your energy levels. Piston bounce reduces efficiency, which reduces energy. A pellet (heavy or tight) that makes significantly less power is inducing more bounce. How much spring life that bounce is worth as stated varies by design. It's really up to the shooter whether the benefits of the heavy pellets outweighs the usual loss of power and possibly shorter spring life.

I personally don't usually use heavy pellets because I lament the loss of power and slow velocities they bring. I know ballistically they're supposed to be better but I haven't seen enough difference for that to matter to me. I typically stay with pellets that provide the best accuracy. Then I look for one's out of that that make the most power. Then you know the gun is working easily at or near peak efficiency.

Also dieseling is tough on springs for the same reasons. Detonation the loud crack you here on a dry fire is really bad on springs. Any gun I've accidentally dry fired broke the spring notably prematurely.

Yes Ron ;).
Talked to Jim Maccari at ARH years ago and he said "YES", too heavy pellets, especially in .177 caliber will shorten spring life (Motorhead/Ron). However, as Ron has also said .... shooting decisions should be based what you prefer ..... springs can be easily replaced.

- I usually go with what's the most accurate pellet and when tuning, try to keep my shot cycle where I know the platform is in balance & not stressed (you can feel and hear the difference).

Shorten spring life?
So what??

I am reminded of a story where a shooter took his prized rifle (PB) into the gunsmith because it was not shooting as accurate as before.
After examining the rifle, the gunsmith said he had two pieces of information, all of it good..
First good news is you have shot your barrel out.
Second good news is you have shot your barrel out.

The spring on my 1st TX shot in excess of 55,000 times at 16fpe before it started slowing down below 13fpe.
That took 12.5 years.
Now I have three TX200s..one at 16.5, one at 13.5 and one at 12.0fpe.
I don’t they will need to be rebuilt again.
Note: I only shoot 8.64gr H&N FTT pellets in them

It takes about 5 minutes to change the spring on a TX200 and then only if you have someone like me talking to you while you are working.

Motörhead can attest to that..🤣

I tried the 'rabbit magnum' pellets in an R1 I had, and they shot like crap. 10.3 were great, but there was something about the design of those very heavy .177 pellets that just did not work for me.

10.3 JSBs? 10.3 JSB or their AA,FX clones are one of the few heavier pellets I'll shoot. Due to their fit and skirts design they don't usually hurt power much over an 8.44. Which incidentally is my best overall performing pellets across my mid power Weihrauchs. The 10.3s actually make as much or more power that 8.64 FTTs.

You'll find the FTTs fit tighter and have stiffer skirts than JSBs in general. That bounces pistons and eats efficiency. Still the 8.64 FTTs are among the most consistently accurate pellets. I still buy them and run them though all my guns because the consistent accuracy is worth the ~1 fpe most of my guns lose with them. I just won't use them for hunting because I want maximum power and flatest trajectory.

I usually shoot the AA 10.3s and like them very much. Very accurate, and a good hunting pellet. If the gun I'm shooting is 11fpe or more (hw50, hw97k, pro sport), then I'll typically grab the 10.3s. R7/hw30s, I usually grab the AA 8.4s or 7.3s. The FTT 8.64s I just can't stand because of how tight they fit into the breech. Just a personal bias, because they are quite accurate. One brand that I have been very pleased with are the Norma pellets. The 9.1s seem to be very consistent on sizing, and are one of, if not the, most accurate pellets I've ever shot.
