LAST EDITED ON Jul-31-14 AT 11:30AM (MST)[p]I got my encore pro hunter 3 or 4 years ago, have had no problems what so ever, it will burn anything you put down the tube, with the factory breech plug. Be sure to get you a .116 drill bit or I think a #32 drill bit to clean the flash channel out every 3 to 6 shots. I have never shot Thor bullets, mine will put 3 shots in one hole using Hornady SST/ML 250 grain bullets with T/C super glide sabots and 100 grains of blackhorn 209. Next best load is a Hornady HP/XTP 300 grain using a harvester crush rib (green) sabot, it is a .430 44 Cal Bullet. Shoots 1 1/2" groups using 100 grains of BH 209. Both bullets shot at 100 yards.
You should clean your firing pin assy about twice a year. Thompson center does not tell you how to do it in the manual. Take the barrel off the action. Pull the hammer back, loosen the allen under the hammer face, remove the firing pin assy. Pay attention to how the spring is installed, it is cone shaped, put it back in the same way. Large end of the cone goes away from the hammer. Never dry fire the gun, the spring can break easily. Good Luck
