a quote:

In my experience, it's down to about eighth place on a list of the ten important things regarding the ammunition. Excellent accuracy (1/3 MOA at 100, 2/3 MOA at 600 yards; at the worst) has been had with the force needed to push the bullet out of .308 Win. cases ranging from 2 pounds all the way up to 50 pounds. As long as the force spread is no more than 20% about average, that seems to be good enough.

No. 1 is get really good bullets a few ten-thousandths larger in diameter than the barrel's groove diameter.

And the list goes on. . . . .

end of a quote:

and I have a question, I can measure NT (neck tension, NT is also stamped on the head of some 45 ACP cases) with micrometers, if you are measuring in pounds are you measuring neck tension are bullet hold?

Richard Lee in his book on modern reloading wrote about bullet release.
