Agreed. Those numbers for a 175 are way too low. You can safely push a 175 eld x or 180 Berger to 2950 FPS in a 7 mag, even in a 24 inch barrel. This significantly outperforms a 6.5 PRC. The 6.5 PRC is considered a little guy for elk in my opinion. It’s a great deer and antelope cartridge though. I also think the recoil with a 7 mag is definitely not near that of a 300 win mag. My vote is definitely for the 7 magYour 175 gr. Load must be factory stuff. (Weak ) My sendero can push A 175 gr. easily 2900-2950. Havent shot it in awhile but iirc. I am like 2950 for my sweet spot. So your going to need to recalculate your numbers a bit.
Also in my sendero I can per Berger shoot their 180gr pills.
But hey I am a huge fan of all 7mms in any shape or size. If I need more power I'll need to hit an 8mm RM. (DREAM GUN). Or some 338 to get a more significant effect on large game.
ALSO I am looking at a 6.5. SOMETHING to add to my collection. So. Get what you want and enjoy.
Also, Muzzle Brakes work so well its nuts. My Holland brake is STUPID AMAZING on my 7RM. Has way less recoil than a 243 win. Probably like some fast 22 like a 22 250 . I bet you can handle that.
Best of luck
