Good point, would not want to extract the loaded round as it would most likely leave the bullet behind and a mess in the chamber. I will most likely try the 1 thou just to test accuracy and my curiosity. But 2 thou sounds like the do all neck tension to me, we'll see how she shoots.

Jbell, I found that 1-2 thou neck tension is what keeps my SD down low teens, 3-4 thou is real bad SD ,paper agrees with chrony at 425. Did a test with dummy rounds to see if one thou would be enough grip to stuff it deep in the lands, it is not, pushes bullet back to 1.905 which gives me .024...
