I have tried 4 different brand and weight slugs on 5 different speed levels and they all shoot 2" groups at 50m.
The zan's seems to group the best (close to 1")
13.4 KO @ 1000fps
13.4 KO @ 960fps
16gr HN @ 945fps
18gr Wildman @ 880fps
20gr zan @ 870fps
I have a brand new Superior heavy liner 500mm, dual TP, slug probe and huma tuning spring.
Reg 140bar
IHS 2 full turns from max.
Shot 150 slugs through the new liner.
