[QUOTE="LoneTraveler, post: 929934, member: 77249"] This is one I have been involved in several time. Did the rifle shoot one group, Then change point of impact for the other group, or did it jump back and forth between groups? When I deal with a jump around I like to look through the spotting scope and have a target on my bench and mark each shot on target for reference and check the cronograph. Paralax in the scope, Cheek weld to stock, loose scope bases, and screws, Uneven action screw torque, bedding problem, and Turn cartridge necks for uniform bullet release. A real good list of possible problems. A weak firing pin spring, A bad lot of primers, Or a bench with a slight move in it when you relax for the shot. Shooting the gun through a chronograph may tip you to a primer or firing pin spring problem by velocity change. Make sure the bolt is down in the proper locking position. I have seen guns shot on a range that if the bolt jerked it would change point of impact. Good Luck and let us know when you find the problem. [/QUOTE]
