Then it would have to be wind-drift.
It doesn't take much to open up groups at longer ranges with bullets that have lower BC's. And standard Accubonds down have comnsiderably lower BC's compared to A-Maxes or ELD-Ms--or Accubond Long Range bullets.Yet many shooters assume some bullets shoot larger groups at longer ranges because of some inherent flaw in the bullet, or "destabilizing" because of the lower velocity.
Instead it's simply more wind-drift. Just a 2-3 mph mildly switching breeze (which many shooters would consider just about calm) will open up groups 3-4 inches at 500 yards due to differences in BC compared to a high-BC bullet like an A-Max or ELD-M.
That's a consideration I hadn't thought of before.
Thanks for that.
