It's a pretty heavy bolt allready, my gun does not seem to be showing any signs of battery, the firing pin channel must have some sort of machining error or rough spots though as it is peening the shoulders of the firing pin where it tapers down. Jard sent me a new firing pin which looked better made then the first one but after about 40 shots it's getting peened by what ever is in the channel. It can't be helping with ignition but the fact it allways fires nice with a deep hit the first shot after manually cycling the action is a bit strange, Dean from Jard said he shipped a new bolt 3 weeks and when it arrives I will take the gun out for another attempt just in case the bolt's firing pin channel issue is causing my second shot light strikes.
