Like archery, weight really doesn't matter much as far as fit of a stock. Arm length and hand size is what is key to stock fitting. Then you have neck length, distance from your cheek to your dominant eye for proper comb height. Lots of things that get pretty technical for perfect fit. Most hunters tend to fit themselves to the rifle rather than the rifle to them which isn't really a good thing. If I were you, I'd go to that bass pro shop and hold as many rifles as you can find to see what fits you comfortably then go from there. A properly fitted rifle won't beat the hell out of you so much at the range as an improperly fit rifle. Less beating equates to more practice which is always best.
