I believe you will find locked scopes are a Short Range BR thing. And I think the nylon locking screws have faded out of use even in short range BR.Could Someone Tell Me About What Percentage Of The Scopes (equipment List Does Not Specify) At The 1000 Yd Nationals Will Be "locked" Or "frozen". Also, What Percentage Would Be "converted" (have Nylon/metal Screws Inserted) Am Trying To Decide If I Need Those Modifications On My Higher Recoil Rifle For Long Range.
