So lately I have been immensely frustrated as I try to get enough neck tension on these to hold the 190gr VLDs I am shooting. Now I know why. The bullet gas stop is almost .001 fatter then the portion of the bullet that my Improved brass is holding on to. Thus I am loosing virtually all neck tension. I am going to have the freed bore extended so that they can me loaded out much longer and thus this problem will go away.
You can see here a bullet on top seated to the needed OAL and below a bullet that very light finger pressure was able to push farther into the case because of no neck tension.
Bullets in the tray are ok. The rest on the table had no neck tension.
This is where the brass holds them. Its almost .001 smaller then the base where the grass seal is.
Once I ream out he freebore longer I will be able to seat them so the neck of the brass grabs here.
