I won't claim to have a vast experience with the Bergers, but I have shot about 400 rounds to include 210 vld 300RUM, 180 vld 7mmRM, 190 vld 300 WSM
, 140 Vld .264 WM. All were off the shelf factory rifles shooting heavy for caliber long bullets at max velocity. And the bullets were seated to fit in the magazine.
In my experience with the aforementioned, heavy for caliber Berger Vld's are my least favorite bullet for shooting short range groups. I have found if you can get groups under 1MOA at 100yds with consistant velocity, guess what, chances are good she will shoot three shots sub-moa @ 1000yds.
I'm no ballistician, and the physics say otherwise, but this has been my empiracle experience in the field with five different rifles in different calibers.
Your mileage may vary, but don't judge your load too harshly until you shoot it at some real yardage.
