What options are available for enlarging the plenum on an original FX Impact. My highest priority is increased shot count, second velocity. I have both the 22 and 30 cal configurations. 22 used mostly for target shooting and 30 for ground squirrels.
Original FX Impact Plenum
- Thread starter nvelkhunter
- Start date
I upgraded my MKII to Power Plenum shooting both in .22 and .30 cal (700mm-Slug liner) at 150bar using JSB 44.75 gr over 1000 fps. and can shoot Varmint Knockers 50grs. slugs close to 1000 fps. (Depending on setting and reg pressure).
