Just chased this down...with my pellet liner being 1:28, the slug liner is 1:26, when available. (.25 Impact 700 mm) Thanks Justin & Jessica @ Utah Airguns. Time frame...no one wants to guess.
.25 cal FX Impact 700 mm Slug Liner Twist Rate

AAA uses similar TR as the quoted FX liners...wonder why AAA has such superb accuracy with slugs? Probably because at our speeds, our projectiles ARE NOT 100% STABILIZED BY SPIN...

I just got mine last week and at whatever twist rate it has is horrendous. Used 36 grain Nielsen slugs with .25 slug liner 700mm at around 900 FPS. Maybe a bad liner but wow it is bad looks like I’m going to get .22 kit and 700mm barrel to compare when in stock.

No typo...I heard this from Jessica that asked Justin while I was on the phone. 1:26 is definitely what I was told and I was surprised. So...what I have done is contacted FX USA (Summer) and she confirmed that the .25 Impact X 700 mm slug liner is actually 1:18. They'll be emailing me specifics and I will pass on any new info. As for the stock pellet liner, 1:28 per my own measurement... 1 full twist for the length of the liner 700 mm or 27.56". Sorry for the bad input. Good catch Ghost & Ackuric.
