I have a dilemma:

I have an AA TX 200 HC Mk 3 - with a V-Mach kit fitted - feels great, No twang at all, shot cycle great and groups well, Very well indeed....but not as accurate as my ProSport, albeit, 'straight out of the box & bog standard' and with a slight twang.

I don't want to ruin an exceptionally accurate ProSport for the sake a the twang reduction.

BTW both in 0.177 flavour and only used for tin chickens.

Any ideas?

Cheers Steve
