There's a couple cartridges I found shot Big Game accurately:
22-250 Remington 700 Classic, 55 grain Hornady V-max, 9 ½, 38.6 Grains Big Game, 0.57 MOA
30-06 Remington 700 ADL, 130 grain Barnes TTSX, 9 ½, 60.7 grins Big Game, 0.72 MOA
Certainly not in the same class as Mr. Sisk's loads/rifles, but these were factory rifles with little tweaking, bedded and free floated. average of three each 5-shot groups...
