i had a leaky reg in my mk2 .25 so swapped in a huma with the xl plenum, i think i have everything lined up but my fpe looks low compared to what others have posted so wanted to check.
- reg 135 (checked with gauge in brass bleed screw hole)
- hs set to get max fps (every time i change reg setting i back hs out and then turn in to where the fps peaks and then starts to drop)
- adjusted the probe to where fps peaks (around 28.8 on caliper)
i'm getting about 880fps with jsp heavies 25.4 so around 44fpe which is much lower than others are posting with same or lower reg pressure.
any ideas on where i might be misaligned? i didnt pull the barrel but checked the set screws just to make sure. i also checked that the cheek rest plate thing was all the way up against the aluminum receiver.
