Currently building a R700 with a Jewell trigger I purchased second hand. Today I was looking at primary extraction to see if I was getting at least 50% of the ramp and noticed that if I cycle the bolt handle up then down only, not back or anything, the firing pin will follow the bolt back down, not catching the sear. Firing pin fall is approx .270" on an empty chamber currently. Could shortening the cocking piece .010-.020" (only what is necessary, of course) alleviate this condition? To be clear, if I allow the bolt to move back any amount after lifting the handle I can hear the sear reset, it was only when cycling up then down with no aft movement does it not reset.
