Re: How to figure Bullet seating depth
I found that the occasional flyer dissapeared when I load each round by checking Ogive contact to case base length after having determined with Hornady/Stoney point the length to the lands. I often put a dummy round together for future reference.
Basically I back off the seating die a bit, seat the bullet, measure base to ogive and tweak the micrometer die to get the ogive to lands distance exact. Slow exacting process but I am not loading in the gross and its part of the process of tinkering I like.
If the cone in the die that accepts the point of bullet is perfect fit for the bullet tip, this would likely be unnecessary as the measurements would be consistant.
Many feel this is wholly unnecessary to begin with.
Each to their own I suppose but while this level of tedious effort is not necessary for a lot of my rifles it has proven to make a difference with a couple. My -06AI is particularly sensitive.
I doubt this porcess would be of any value if I was shooting jambed into lands but when I set up my load for my hunting riifle, I wanted to make sure I could unload a round without pulling bullet and spilling powder. However rare that might be, it is too often.

We are very close to this point now.
