I have a TC Encore that I just put a 26" 30/06 bull barrel on. I bought the gun as a pistol in 7mm/08. I fired a couple of boxes of ammo thru the 7mm/08 and the gun fired every time with exceptional accuracy. I switched the barrel and put a rifle stock and fore-end on and now the gun fails to fire sometimes. It seems that the fireing pin is not striking the primer hard enough (only slightly denting the primer). This does not happen on every round but erratically. I put the misfired round in my bolt action and they fire. i have also added a hammer extension on the Encore so it can be cocked easier with the scope mounted low. I have read that the factory hammer springs on the TCs were a little weak and that adding a hammer extension could effect the hammer fall, however, I had the extension on the 7mm/08 as well and never had a misfire. Has anyone had this problem with thier Encore?
