Air Arms Owners Club

My Air Arms 12 year old TX200HC .177 is doing 670 ft/sec and 8.39 ft/lbs. It did 11+ ft/lbs when new. Its done many thousands of shots. I think I probably need a new spring.
It’s just used for target shooting, doesn't need to be massively powerful, but I would like to get it back to 10-11 ft/lbs.
So do I go for a straight replacement or an upgrade with a Titan XS ?
Thoughts, advice, etc. would be appreciated.

Are you sure it’s the spring and not the seal that’s gone south.

as stated the piston seal could have gone, also the o ring breach seals.

Many thanks, will check those suggestions.

imho if you do decide to replace the spring, use the AA spring. no need to cut, dress it etc.
