Re: Advice please on my finicky .308...
Rheinhardt, if you get in touch with anybody on one of the USA's long range highpower rifle teams and ask 'em about how they seat their bullets, you'll learn that they push 'em into the lands a bit. Even when the world championships are held and sample ammo is sent to everyone, they have their barrels chambered such that the bullets get pushed back a few thousandths when the bolt is closed.
Best accuracy has always happened when the bullet is pushed into the leade. Otherwise, it won't be as perfectly centered in the rifling when it starts moving down the barrel.
