Steve I was wondering if and when you leave the jam nut out does or do the velocity screw move or travel on ya? I didn't know if the harmonics of the rifle when dis-charged would be an issue as far as the adjustmen screw moving all over the place on a person. Thanks SteveSupercharged86 wrote:Randall, the other two adjustments that you'll play with are the hammer stroke length and hammer pre-load, both from the rear end cap. I choose to leave the brass jam-screw out all the time, this way making adjustments through the new access hole are easier. If after finding the right combination of settings you want to throw the jam-screw back in, that's fine. But I've never had the VP screw change on it's own even after hundreds of shots. Just take your time and measure precisely, keeping the hole to a minimum and it will all look fine when your done. Cheers. Steve
