[QUOTE="arrow179, post: 2850994, member: 106650"] I have a Tikka T3X action with a Carbon6 prefit barrel (SAAMI spec reamer) torqued to 80 ft/lbs. Using PT&G 300RSAUM go and nogo headspace gauges. Neither one will allow bolt to close. I checked the difference between the 2 gauges and the nogo is .004" longer using Hornady headspace comparator kit (.420" bushing). When I measure brand new ADG brass it is .0005" shorter than the go gauge and the brass will allow the bolt to close fairly easily. So is the rifle safe to operate? I'm assuming that it is but I would consider myself a novice when it comes to gunsmithing. Any help or advice would be appreciated! [/QUOTE]
