Re: Which Detachable Magazine to get ???
sometimes you need to relieve the stock a little to get it to fit perfect but not usually a lot , as for mags with .308 based cases you can get 5 and 10 round mags and with 338 lapua sized cases you can get 5 rounders. i don't know where you would buy them in oz but a google search should get you their website and a short email to them will give you a stockist near you i would guess.
i should say that i run all my rifles in mcmillan stocks so thats what my experience is with.
