Re: Opinions please... on a hunting rifle
the stock is going to be difficult to upgrade while trying to keep weight in mind. the reason to upgrade a stock is for 2 main reasons (function/fit) and overall toughness. a good stock will fit you swell as you barreled action very nicely. you also have the option of changing LOP and the option of a raised comb, which if you did end up using that springfield with a 56mm OA you would probably want a raised comb, especially if you were planning on putting a base such as a 20 moa on. i think everyone here for the most part will send you in the same basic direction, which is McMillan, Manners, and Bell and Carlson. try and keep your selection to there different hunting or varmint styles to cut down on weight. but these will be strong stocks with good bedding blocks to enhanced accuracy.
as far as the scope goes there are many factors a few of which being, what are you familiar with Mills, or MOA. what is your target animal. what is your main focus (weight, optics quality, durability, etc...) and the most important limiting factor PRICE. with those answers people may be able to help you better. if you want to shoot a 300 win mag 600 yards but you do not intend on getting a base with any sort of cant a scope with a lot of elevation must be chosen. these are all factors that must be considered.
