I have a project in mind, not a full custom job, just thinking about a couple mods to a 308 Vanguard S2 Deluxe Sporter. The barrel is the biggest thing for me as I don't have any experience in choosing one. Been looking at contours and am considering something heavier than existing but still can be considered general use for range, varmint, big game? What's a good choice for something that could be considered quality grade could this be an easy DIY? Don't like the walnut stock either and am thinking of changing to something more appropriate for the field that doesn't get dinged so easy. Need a scope too but I think I know what I want for that already. Thanks for any pointers and suggestions. Link to barrel contours for reference: http://www.shilen.com/contours.html
