Anyone shooting NSAs through FX STX superior 1:24 .25cals?

I could never get the 26.8’s to shoot out of dreamline or impact. 600mm, or 700mm, and I have both superior 1:24 and superior heavy 1:18 in both lengths. The 29.0 and 29.5’s were fairly decent at 50yds. It’s possible I was trying to push the 26.8’s too hard. I remember finding sweet spots between 800-900 with other slugs rather than trying to push them 940+.

What was the sweet spot for hybrids with the dreamline? I never got those to shoot well except in my impact at really high speed.

I’ve had great luck with most slugs in my impact both superior and superior heavy.
 
I've found great results between with STX Superior 1:24 at 125bar, about 3
3.3 turns in on the 1.5mm screw, 22 on the wheel, velocity between 921-933. The extreme is 12, but the SD is about 4.4 same hole accuracy at 50.

Using post 9/21 version Dreamline tac25/600 superior + plenum, huma reg, 1:24, 125bar, pw 22, 3.3 rotations of hs screw, getting 4 mags on 500cc 250bar fill from 250-150.
