310 yard shooting

I believe Applied Ballistics still has an offer...If anybody can actually show this phenomenon to happen, repeatedly, in a controlled environment, they’ll pay for your entire trip out to Applied Ballistics to show them. If you can’t show it to happen, you pay for the trip. They want to see it, study it and prove/disprove it. Unfortunately, in all the years this offer has been on the table, nobody has ever taken them up on it! Like you said Centercut, the spiraling is less than the diameter of the projectile, so although it can stabilize, the groups don’t get smaller, they just don’t get twice as large at twice the distance.

Mike, seems odd, but its well known among precision long range shooters. 

Long range target rifles that only give 1/2 moa at 100yards have been known to deliver 1/4moa at 600+yards.

I have observed something similar with pellet rifles. But at much shorter ranges ... 10M groups tightening at 20-25 yards. Wind negates meaningful tests I did back when I was interested in such.
