Recently did a little spring work on two rifles and they are proving to be shooters. Top target is my CS 452 that I put a Yo Dave spring in. It now pulls at 1 lb. 6 oz. The pic is 5 shots at 50 yards.
I also put a Yo Dave spring in my Tikka T3X CTR in 6.5 Creedmoor and it pulls at a very crisp 1 lb. 10 oz. Middle pic is a 4 shot group at 100 yards with Hornady Factory Precision Hunter, 143 gr. ELD-X and the bottom pic is a 5 shot group with Hornady Match ammo using the 140 gr. ELD-M. Squares on the target are 1"
