Took advantage of the weather and hit the range to check my T/C Compass after mounting it in an Oryx chassis, changing the bolt handle to a Glades Armory handle (https://gladesarmory.com/product/thompson-center-compass-stainless-cross-hatch/) and upgrading the trigger with the M*Carbo spring kit (https://www.mcarbo.com/thompson-center-compass-trigger-spring-kit.aspx). This rifle shot really well before these changes but now it is nothing but light strikes. Tried several brands of 308, both military and commercial and also stripped the bolt but didn't see any grease, oil or debris that may have affected the firing pin. The firing pin seems to protrude through the bolt more than the dimples on the primers of the misfired rounds and the bolt face is smooth and clean. Unfortunately, I don't know what the spec is for firing pin protrusion. What else should I look at before putting all of (or one component at a time) the factory equipment back on?
