[QUOTE="SteveBurton, post: 988931, member: 59541"] ShootnMathews, I was reading an article on the 6.5x47 Lapua round and saw this. "Mysterious Flyers Noticed -- Traced to Non-Uniform Neckwalls With this rifle, there were some challenges early on -- I noticed that I was getting an occasional, unexplainable "flyer". This happened a couple times in matches. I would feel I had a sure 10, and it would pop out to an 8. That made me suspicious so I turned those cases upside-down in my ammo box for later inspection. When I carefully measured the "flyer" cases with a tubing micrometer, I found that the necks were a bit thicker than the rest and were NOT uniform. On some of the "flyer" cases the neckwalls had as much as .002" total variance (one side was thicker than the other, e.g. .015" vs. .013").

It appears that you found the culprit with bumping the shoulder but you could also check neck thickness to see if that contributed to the flyers. Good luck this season.:) [/QUOTE]
