Just sighted in my new 16FSS in .270WSM at 100 yards 3 groupings at under 1/2 with first box of shells! Using a picknic table in tha back of my truck. On the picnick table I used a Caldwell steady rest. Shells are cheap @ss winchester power points. I went to buy accubonds but everywhere I went were sold out. I'm glad they were as I feel there is no need to try anything else. I beleive that the 1/2" is human error. I would bet if the gun was locked in a vise all 3 shots would be in the same hole!
regards!
