Basically, this is not a one-time thing; as the leade advances due to erosion, you
have to follow it by seating further out or you will lose accuracy.
I called a Long range Shooter friend that has been testing for over 10 years and he said that if you seat the bullet at the depth
where the bullet is just touching the lands of the rifling you can expect the best accuracy. He talks with some of the major barrel makers and other Competition shooters that are 1000 yard shooters
and they all claim that the small pressure spike is Normal and Safe, but they all seat to the Lands.
They do NOT use Max Loads, they use accuracy loads and usually just 1 specific bullet , they dont change weight, or Brand of bullet...when they find the one that performs the best in their particular rifle, they stick with it.

ok i came up with
2.720 with the 165 sierra HPBT bullet jammed into the lands AND I MEAN really jammed in there.
so 2.700?
none of my loadbooks have this weight of bullet.
they only have 168's of this type
the sierra book calls for 2.750 with a 165 sierra HPBT .
that is impossible in this rifle.
they used a savage vs12ss rifle 1-10 twist 26in. bbl.
this shit drives me crazy!
