I shoot the Light Mags in my .308, my 30-06, and in my 7 Rem Mag and love them. However, given your hunting area, I agree with Hawkeye - if you are hunting an area where the .243 is adequate, you don't need the additional 1,200 fps. As to accuracy, they all shoot well out of my rifles - sub MOA, and due to their fairly recent manufacture, I have pretty much quit reloading since I get the velocity I need / want for hunting out west (lots of long range shooting here). My advice, buy a box of several different manufacturers amunition and shoot the one that groups best out of your weapon. OH, and the velocity thing is mostly in our minds :-) Neither you, nor the deer, can tell the difference between 2,810 fps and 3,000fps at threehundred yards. I shoot higher velocity because we do have some 400 + yard shooting and I want the extra energy out of the 150 grain bullets I shoot - again, maybe just a mind thing, but I feel better about it.
