[QUOTE="LoneTraveler, post: 2096032, member: 77249"] A gunsmith friend and I replaced the spring in my old Rem 722. It had the dime slot in the sear sleeve, Put washer in the grove unscrewed the firing pin. He reached up on the wall took a small turned metal sleeve off a nail, Slid it on the firing pin, Screwed the firing pin back in the bolt and exposed the pin, I held the pin on a hole in his bench block he drove the pin out. The original spring was so weak that on firing, The firing pin was backing up in the bolt and the primer was pierced and smoke and gas came back through the bolt. By putting a piece of 2X2 wood on a bathroom scale. hooking the sear sleeve on the 2X2 and shoving weight down the spring was over rode at 15 to 17 lb. I done I done the math and the spring was just to weak. With the spring change the 40 year old rifle at the time went back shooting less than 1" at 100 yds, and no more smoke gas flying through the bolt. [/QUOTE]
