EXCELLENT AMMO. My father gave me his 1976 Sako 22-250 2 years ago. I shot it several times w some of his older boxed ammo, and could only get 1.5-2" groups. I was not impressed so I did not use it much.. I read that the twist rate was 1 in 14", so decided to try these loads with lighter/shorter bullets. I WAS AMAZED -- 1/4" and 3/8" groups! Could not have expected better! Shot from bench on sand bags, but in the wind in open area and not using my best technique. WILL DEFINITELY ORDER MORE. My chronograph was not working, but can assume great velocity uniformity by group size.
