I' d say BJ (not too gently) put one near the 10 ring.

=====================
Consider:

The Ph D. measures it with a micrometer,
The foreman marks it with a grease pencil,
The workman cuts it with an axe!

Or similarly,

The match shooter hand weighs his loads to a one fourth of 1/10th of a grain,
The bench rester measures his groups to a tenth of an inch,
The old elk hunter hits the " pie plate size" kill zone on the elk with a bullet that was up to the toughest task foreseeable.

In each case, while the others sweated the trivia, the workman and the old elk hunter are the ones that focused on the end result, out in the field, under sometimes trying " non-laboratory" conditions.
=====================

I recommend going heavy for caliber for elk; 150 to 160gr for a 270 IS heavy for caliber while 150gr in a 300WinMag ISN' T heavy for caliber. Penetration is KEY --magnum or no magnum. Consider giving up a little in your bench group for many inches of increased penetration through thick and thin, hard or soft, square or raking. Then, when you are back from elk hunting, put away your " heavies" and go back to poking paper with 150' s -- paper and light weight animals penetrate very easily, elk less so.

Just wanna see you win in the field where there is no 10 ring.
