What’s everyone running FPS wise for hybrid .30 44.5gr slugs in their 500mm pellet liner?
Tuning New Fx impact x mkII compact .30 slugs tune

I just power tuned mine today. My compact has a Talon Tunes dual transfer port and pellet probe. I set the reg to 155 bar. I am now getting an average of 900 FPS with promising accuracy. 3/4” 5 shot groups at 50yards in 10mph wind. My previous tune had them going 875fps and could only get 1.5” groups at 50yards on a calm day. The JSB 44.75g pellets are going an average of 912 FPS with this new tune and very accurate. I will go out to 200 yards this weekend and see how they do. Hopefully the wind will be calmer.

I’m shooting the hybrids out of a superior heavy that I purchased as a 700 and lopped 200 off. With the reg set at 126 according to an edgun digital I’m pushing them at 880-885 getting moa at 100 yards. Haven’t shot groups beyond that yet but look forward to when coyote season ends in a few days
