Ebb, hope your health improves. It sucks. At the Ohio Sate shoot about a decade ago I had to stop shooting after the first 50 rounds. I could not lift the gun. In 2012, I came in second at the Michigan State shoot after running 200x200. Things can change quickly.
I still battle issues but have never given up. Sounds like are wired the same way. Keep on keeping on!
Hope you are back shooting 10k rounds a year and building new toys soon. Good luck!
