Has anyone here ever tried a series of cold bore, first shots,with their light vs heavy rifles, from various field positions,and watched where they go as opposed to shooting "groups" in a series of three or whatever?
Yes. We use milk jugs.
To the 400 there is no difference. For me.

I essentially agree, out to 400 yards in controlled conditions, it's doubtful there's much difference.
Ditch the bipod, run stairs til' you're heaving, get some adrenaline going, and do it at 8,000' elevation, and I contend you'll see a difference.
