[QUOTE="Greyfox, post: 1786871, member: 10291"] Bryon Litz talks about this in his 1st Edition, Applied Ballistics in Long Range Shooting. Paraphrasing, the angular group size will not stay constant at long range due to the spin/gyroscopic effects on the bullet, and groups could be expected to increase 25%. My own experience with my best shooting LRH rifles/loads with sub .5MOA accuracy is that they can maintain pretty consistent group size between 100 and 500 yards. Out at 800-1000+ yards I’m usually at 1.5-2x of my average MOA group size. My competition rifles at the longer ranges are generally better. This seems consistent with Litz’s statements.. Of course, mirage, wind, lighting, parallax, etc. can be factors....and if not at optimum, can(and usually do) degrade consistency further. Just my experiences. [/QUOTE]
