Got a 600mm in .25 coming Monday, going to shoot 40-50 grain slugs wanting to shoot 950 -1000fps How do I adjust the regulator, hammer spring , and dwell time properly? I haven't been able to find any video showing how this is done, thanks.
Thank you weevil, I read the entire manual and it is quite thorough. The manual didn't mention this, but I was wondering if one can add a tiny drop of silicone oil periodically to the witness holes to help further the longevity of O rings? I also liked the idea of slowly releasing the air pressure screw when turning the regulator down when tuning it, no need to dry fire it.
