Help me decide 7WSM, 6.5 PRC or 6 Creedmoor

I’d look at 6.5 PRC personally. I already shoot 6.5 SAUM and have found it to be a great performing SA round. The PRC shouldn’t be far off with the advantage of factory ammo. We have the tooling on order and hope to put one together soon.

What are you hunting? I’ve never been a big 6mm guy but guys get the job done with them.
 
I personally would go with the 7 wsm but would make sure you have brass for it first. It hasn't been horrible to get this past year but there are times you don't see it for quite a while.
 
7 SAUM. Norma brass has been easy to get and works well. If you are hunting I say stay with the larger caliber. The 7mm SAUM can launch a 162 ELD at 3,100 FPS. The 6.5 PRC can launch a 147 ELD at 3,100 FPS. Both have basically the same ballistics but you will get roughly 10% more energy on target with the 7mm. If you need to get factory ammo then definitely do the 6.5 PRC.
