mate, you are 100 % correct that the differences are marginal, but we're shooting the breeze, mainly because we are stuck behind a computer rather than out on the hill where we would rather be. That's kinda the point of a forum, if you find it monotonous, perhaps you should scroll on?
Thanks for the information about 110 and 100 grains though...I'll look into it - I'm still shooting 130 in my 270.
