About to start load workup on y 300WSM, I'll be using Norma brass and H4350 and H4831SC. I'll be trying most of the Barnes TTSX and Accubond offerings. My question comes down to primers. I have about 6k Federal Match Large rifle and about the same in CCI BR2. I have 0 Magnum primers.

Ive read a few posts on the matter but nothing really to sway me to invest in Magnum primers. Any thoughts to contradict just using the standard LR Match primers?

Id rather not burn bullets and powder jsut to try both primers. Perhaps the safe route is just to start with Magnums but if I can avoid it, I just as soon keep all my rifles on the same primer diet.
