The only things that really matter to me when spending a lot of money on a stock are weight and ergonomics. If you are talking about a standard hunting style stock, given the same weight, I would purchase the cheaper. That is usually Bell & Carlson. I have a couple of Manners stocks and have had another. I paid for the fact that it is super light and more ergonomic than a standard hunting stock. I have had several Bell & Carlsons and several HS Precisions. The HS Precision is definitely nicer fit and finnish but not worth the money in my opinion. I have never owned a Mcmillan but have been around a few. I prefer Manners. I would expect a Savage to shoot around .5 MOA with a hand load it likes. The accustock is more than capable. I would only get a new stock for it if you have exhausted reload tweaking and still have not achieved your desired accuracy.
