**** that is screamin...I do the same thing as you except the(.000 if im near max load)but I use smaller depth changes as .040 is a huge change...the factory barrel that was on my 300 liked anywhere from .025 to .085 depending on the bullet but both my 260 and 300 shilen barrels like the bullets close no matter what bullet. I shoot 220g and 210g smks and 208g hornadys in my 300 and 139g lapuas 142g smks and soon to try 140g hornadys in my 260.
