Ok so this is my first post here and I hope to not seam like a moron. Well I just put together a Remington 700 long range 300 winmag with 20 moa rail night force med rings with a vortex viper 6.5-20x 50 . that being said I wanted to shoot it as I finished it last night sportsman's had a sale one the prograde 300win mag match grade with 210 berger vld tagets. So get all set up shoot it at 100 and it groups amazing 3rd shot sighting it in punches the center and the following four all touch it. So natrually I'm excited it all works. Then I went to 200 my group looked like I traced the outside edge of a pie plate.sugestions.? I will be building a load for it of course but is this what I should expect from berger vld? Should I go back to my tried and true accubonds? Any idea what's happening?
