depending on what you have to throw around i would say invest in a stock that is fully bedded
reason being is since your looking at long range shooting the free float could help you
not to say you can't get good results with a standard stock, cause you can, just the free floater may help you
all the brands listed are good
i have a winchester
but if i was to pick out of the one you listed i would go with the one on sale
love the idea of a stainless barrel
my best shooting barrels have always been stainless
don't forget to get some good glass too
i usually look at Cabelas bargain cave or surf the net for specials
when ya get her send us some pics and range results
