Is there a significant difference in the heavy and slimmer CFW contours?

My son has, the Heavy Contour Proof, 24 inch, in 7 MM PRC, Tikka Action, Stocky's Carbon stock and with, Near Max Loads of, StaBall HD, W/ 180 ELD-M's @ 2,985 FPS, can obtain, groups from, 1/2 MOA down to, .314 ( Ctr to Ctr ) with,.. 5 Shots.
He slowly shoots, 3 shots,.. WAITS, a few minutes then, 2 more,.. it's NOT,.. "Rocket Science" for, Us

IMO ,. Cold Bore, "Fliers" usually come from, 1) a POORLY Stress relieved Barrel or, 2) the IMPROPER Bedding of, the Bbl'd action in the Stock.
And,.. 3) Mis-Matched,.. Bullet to,.. Twist

5-10 shot groups often are an indicator how the wind is blowing on that particular day! Shooting in an underground tunnel or chicken house is different.
