Slapped on a new Nikon Pro-Staff on my 3 year old Tikka .243. Had a box of Winchester 100 grainers. Lined it in at 50yds. Moved out to 100yds, 3 shot 3/4 in. group. Moved out to 200 yds, 3shot 1 1/2 in. group. Thing just keeps shooting better and better! I used a styrofoam plate and just centered it with the Crosshairs. Worked pretty good for these, heading for 65 eyes!!!!
