[P daniel13]

Hi any one whit TBT tuning kit full power in your Hw 97 , and how good is? What is the FPS? Thinking about one of those,, Thank you for your help

I have one in my HW77 with the 25mm piston , not the newer 26mm. It’s make about 13.5 ft.lbs.

I put a reduced power one in a HW97 that I let go. I don’t have numbers for it.

I know you’re looking for experience with full power kits, but I really like the TBT kits.

I personally steer clear of the TBT kits if a Vortek / Maccari equivalent is available! A few instances of the TBT spring guides failing. My 2 cents

TBT is a really poor guide and top hat made.

If you want a really good kit try a weelsh willy from goodfield-gcp

I have used Vortek and TbT kits. Very nice kits, I have had no issues with either.

I can recommend the ARH kit along with a Vortek seal for your tune. No experience with TbT kit. My HW95 is absolutely silent cocking and a dull thud with the shot. The rifle averages about 17 FPE after almost 8K pellets and sometimes I can shoot MOA at 25 yards but not always. This is the shot cycle recorded via an iPhone at 5' to 7'.
