if you want to try the Elite and do not do so you will wonder forever. Put it on the gun, what is the worst that can happen, you do not like it.... Then you get to put another scope on and shoot some more.
Go to your favorite supplier, order a 300 WSM die set, the shell holder and two of the big blue WSM, MTM style 50 rd boxes... yep special box. Get a can of VN-560 and some Hornady 168 BTHP Match. Load 74 grs of 560 and set off about .003 to .010 then if you do not like the result send her down the line. Oh, if you want to try 180s, use 72 gr of 560, for just over 3,000 fps.
There was a guy on the net selling WSM once fired Win nickel brass. The brass comes from the Winchester gun factory and was used in test firing brand new rifles. It is cheap and about as good as it gets for once fired. Just do a FL resize and you are in business. Oh, typical Win, they beat the brass into proper length so you need to deburr and champher.
