Benjamin Marauder .22 Huma Regulator Question

Jump to latest Follow Reply
"Helimech"I would just play around with your tensions and lengths of the hammer. I’d leave the transfer port screw out as far as you have it, but try increasing tension and length. I got extremely lucky with mine. It was nothing but a Hail Mary that ended up working out. When my new hammer spring and transfer port arrive, I’ll be able to give you some better advise because it won’t be a guess when I tune for more power.

Thanks for the reply. I have been trying different throws and tensions. Thank god for YH compressor or I would never try playing around like this. I'm getting closer but then I changed the TP to .161 and had to start over. Dang. lol

"Dairyboy"So the trick is when tuning a regulated gun you want to find your maximum FPS at that pressure. I usually start at 6 turns CW on the hammer spring and while throwing it over the chrony and record where there at and back out one turn and shoot a shot or 2 and keep doing that until you get to about 20-30fps below your maximum FPS you had. You'll hear it get alot quieter.
