Playing with seating depths today and I can drop a projectile in then chamber a case with only about 0.01 Bearing surface in the neck so Obviously going to have a massive jump to the lans

But just how much bering surface needs to be in the neck
To make a good Reliable load a mate told be he always has at least a projectile diameter of bering surface in the neck
But in this case that would be a .264” jump to lans
Which is massive

What’s your options

if it wasnt me that told you thats what i do and its worked so far for me
