This paragraph, quoted from the referenced article, is what has me on the fence . . . as I have a 7 SAUM on a Tikka T3.

"7mm PRC vs 7mm SAUM

Two very evenly matched cartridges, if you already have one, it would not be worth it to get the other as well. The 7mm PRC has a lower 30 degree shoulder angle, so it may feed from a magazine easier than the 7mm SAUM, and the 7mm PRC has very slightly more powder capacity so offering very slight muzzle velocity advantages, but hardly noticeable. With Hornady behind it, we should also see more available components and ammo for the 7mm PRC compared to the scarce 7mm SAUM. The 7mm PRC is basically the 7mm SAUM ballistic twin that get better factory support and marketing behind it."
WiFowler: I'm not going to try to convince anyone that we "need" more new cartridges to fill some non-existent void in our shooting spectrum, the 30-06 pretty much covers anything we may need, it's done it all, but building new rifles and tweaking existing cartridges to make them just a little "better" is what entertains me and that's good enough for me.
