Hank how many shots in a group did you shoot?
5 shots

I believe the metrics you are looking at ( bullet weight, run out. powder charge variation...) are all within the acceptable range and well within the variability you would get from fed gmm. If you are simply using neck sizing dies, how many times has the brass been reloaded?

this was the brass and powder and original bullet pulled apart and put together again to test if the neck sizing and setting is reducing the accuracy in my setup.

Lee collet die should perform well for you, the neck tension should be sufficient for what you are doing if you follow the adjustment steps. Do you size rotate case and resize again?
