Re: Strange accuracy at LR-Thought?
It could very be happening just based upon a high ES. I had two loads for my 300WM using 210VLD's. One at 2800FPS that produced sub.25MOA at 200 yards with an ES that was 30FPS. The other load at 2900FPS, .5MOA at 200 yards, and an ES of 8FPS. The difference between the two loads was powder choice, H1000 vs Retumbo in the second load. The second load clearly outperformed the first load at 800-1000 yards by 4-10". A 30FPS ES is high for long range shooting. If your higher velocity BT had an ES advantage, it could account for the better accuracy at long range. Large ES spreads are generally not evident when group testing at 100-200 yards, but quickly rears it's ugly head at long range as the bullet slows down at longer ranges. Just a thought. It may not be the cause of what your but could be worth checking out. IMO.
