bfoster, I've taken a factory load, fired it in the gun,then measured(with a blade micrometer) the case head, and used this as a guide when reloading ammo for the same gun to indicate pressure. This seems to work out well. The only thing is to get used to measuring to .0000. This is something you can't really do accurately with a calipers. Micrometer is a must for this.
