I'm a newbie to building up a custom or semi custom rifle so please forgive me if this is a dumb question. I want my next rifle caliber to be 7mm WSM and I like the Vanguard S2, but they don't make it in 7 WSM. I've considered 270WSM, but want the better ballistics of the 7 WSM for LR. (Am I splitting hairs, considering I'm not in any formal competitions?) The V S2 does come in 270 WSM, but I'm wondering what would have to be done, and if it is plausable to rechamber it to a 7WSM. Obviously a new barrel at around $350 + mounting for starters. I've also read the articles on building a low cost LR rifle but it seems like I would have to buy more parts and integrate them; action, trigger assembly, bottom metal, barrel, stock, and what else? This sounds more expensive than a $485 + 350 + service to rechamber and rebarrel. Thanks for any advice and not thowing dead squirrels at me!
