I am the fan of the transfer, the standard and verifying, No Sinclair, no Hornady, no dial caliper, I transfer the chamber dimensions from the chamber to the seating die. Again, I drill the flash hole/primer pocket to a diameter that will accommodate a push rod like a cleaning rod or a gun friendly wood dowel. I simply seat a one of the bullets I am going to load into a case I am loading (with good bullet hold), after seating the bullet I remove the bolt, chamber the transfer, then with a push rod I push the bullet out of the case until it contacts the rifling and stop, After pushing the bullet out I remove the transfer to the press and install the seating die with the ram up.
The die must be adjusted to crimp and or not crimp, then with the seater plug adjusted/backed out to prevent contact with the bullet and the die secured with the lock ring I adjust the seater plug down until it contacts the bullet. At this point the seating die is adjusted to seat bullets .000” (zero) off the lands. After zeroing it is possible for reloaders that are familiar with depth micromeres, height gages and dial calipers adjust the seater plug to seat the bullet bullet ‘off the lands’ by adjusting the height of the stem above the seater die if they understand the concept of ZERO.
This method/technique allows the reloader to make one adjustment instead of raising the ram, making an adjustment then lowering the ram, removing the case, measuring, then going back to installing the case in the shell holder and raising the ram and making another adjustment then repeating the procedure again and again etc..
Bullet hold, I do not want the bullet to move, I want the neck of the case to hold the bullet, I want all the bullet hold I can get, shredding the neck allows the bullet to move with the slightest amount of handling, again, I want a transfer that allows me to transfer the dimensions of the chamber to the seating die. The modified case comes in one size, chambers come in all sizes, when forming cases I off set the length of the chamber with the length of the case, I am not stuck with one size modified case for all chambers.
Seating off the lands, again, I am the fan of ‘bullet jump’ I am the fan of the ‘running start’ I do not want my bullet setting still at the lands when pressure builds behind it. I do not want my bullet to stop at the lands, there is something about ‘time as a factor’ that causes me to want ‘the running start’.
