Testing Slugs with FX Impact - PELLET & SLUG different liners and Barrels

Would someone know the spec's of the new ( Gen 2) FX 700 mm slug barrel:

I gather its a 1:16 twist, 700 mm LG, is it traditional Land/Groove, Polygonal, smooth twist or smooth twist X barrel.

Knowing the Land / Groove dimensions (eg. .217/.214) would be great.




Just fx, according to Matt D. That is confidential
 
 

Forgot to mention, jsb 0.22 beast 34 gn out of the slug liner best group

The FX chart says it's 1:15 twist https://www.airgunnation.com/topic/official-fx-stx-barrel-liner-twist-rates/

Rifling is rolled into the tube from the outside just like the STX barrel but the choke is different.

Matt Dubber says it never needs cleaning.

Here is a video explaining slug liners. It's long but you should watch the whole video.
