[QUOTE="Mikecr, post: 2907735, member: 1521"] I recommend NOT relying on a load starting pressure that an in-the-land (ITL) relationship produces, and instead, finding best initial CBTO that is OTL. With this, you can ignore land erosion for the accurate life of the barrel. That is, through full seating testing (like Berger recommended), find & set best OTL CBTO. Never touch it again for THAT bullet and barrel. When you seat bullets ITL you're introducing that condition into tune. You'll be a slave to it, and perpetually chase fleeting results. That works for under-bore competitors preparing for each weekend, but not so much for most hunters, with hunting capacity cartridges. My approach with actions is to buy as, or modify to, single shot. I don't need any magazine compromise. I can pull a single round out of my pocket and kill what I'm prepared for then. I don't need to eject my brass off into the weeds somewhere either, so I always delete ejection and pick rounds. That's not so easy with a magazine in the way. [/QUOTE]
