I would try and make sure you have enough magazine length to load heavy bullets far enough out in the case. In my dads 300 win mag I have to stuff the big bullets deep to fit mag length. I wish I had a longer magazine to seat them farther out so I could take advantage of more case capacity.
I am becoming a believer in Seekins rings too.
Have you consider swapping bottom metal and going to an aics 300WM 3.715 mag? Some people hate mags but it is a nice option if you wish to increase length.
