What load does your Featherweight favor?

What kind of aggregate sizes of 5 shot groups are you getting (perhaps the aggregate of a few consecutive groups)? Occasional great groups don't interest me much, but consistent groups are another matter. I really don't expect factory big game rifles to honestly agg MOA for 5 shot groups - but reasonably close would be nice.

This rifle will be shot mostly standing, using sticks. The weight of the longer barrel and the cheekpiece are the chief reasons I am currently leaning toward the Sporter. I get a little twitchy on sticks (everyone does).

Uncle,
My Featherweight (270) will always stay within 1.5 inches, often better if I am on my game at the bench. I have more accurate rifles but carrying that Mod 70 fills me with nostalgia and under field conditions it's more accurate than I am anyway.
It's favorite load is 54 grains of WW 760, 130 grain Grand Slam, CCI 250, RP cases. 3050 fps.
