7mm mags are more plentiful because they have been around longer. The chamber and twist rate are generally optimized for ~140-160gr bullets.
7mm prc chamber and twist rate is generally optimized for new extra long/heavy bullets.
It is often argued that 7mm prc is better optimized for "long range", but the 7mag is a very proven round to 1000+ yds. With either round you will be holding over for bullet drop. You will just be using slightly different numbers.

Not sure if it matches what you are looking for, but here it is:

Not trying to hijack the thread but what about meat damage ? I shoot 160 grain nosler partitions out of my 7 mag and it is manageable. I've seen critters shot with that PRC and it's devastating...although I'm sure people have horror stories of the 7 mag. Can you get more of a bonded bullet in those PRC's as opposed to those poly tipped ?
Meat damage is a product of shot placement and bullet choice. Zero difference between rem mag and prc in this department, they are both .284's burning similar amounts of powder. High BC "match" type bullets commonly ran in the PRC kill things really dead really well but they can also get a little messy with bad placement. You could absolutely run a NP in the PRC if you wanted to and vice versa

Shot a deer with my 7mag years ago.
Shot placement was off a bit ,hit both front shoulder.(Perfect broadside)
I basically cut the front legs off with the hide,while skinning.
It was BAD.
Can't remember for sure, believe it was a nosler BT bullet. 150 grain.
Loaded above max charge. 100-150 yards.
Shot placement is everything.

Any experience with these two. Looking at a getting a new rifle and curious if yall like one or the other better. Thanks.
They have essentially the exact same case capacity and are basically ballistic twins. Throated the same and both with the same twist and length barrel neither has any advantage over the other.
Not sure if any of the premium brass companies make 7 Rem mag brass so maybe brass quality favors the 7 PRC.
If you want to shoot the high BC heavy for caliber .284/7mm bullets and you want something you can buy off the shelf at your local shop then a 7 PRC will be what you want because I don't think anyone builds a 7 Rem mag with a fast enough twist to shoot the high BC heavies. If you only plan to shoot up to the 160's flip a coin and pick whichever one is in a rifle you like best.
I'm sure Karl will flip me *censored* for saying this but I'm no fan of anything with a belted case so, for me, I'd go 7 PRC just because I hate anything with a belted case. ;)
I don't have either but I do have a 7mm Blaser mag which looks nearly identical to the 7 PRC and many years ago I had a 7mm Weatherby mag that was a beautiful rifle but oofff the worst shooting POS I've ever owned. If the PRC would have been out before I had my Blaser built it would have been a 7 PRC instead since brass for the Blaser is become nearly impossible to get.

Rifle manufacturers that chamber both will use the faster twist and reduce the need to have several batches of 7mm bores with varying twists. Check Remington’s site if you don’t believe me. Oddly enough, the old 1:9 twist stabilizes 180gr bullets just fine.
Having a belt doesn’t mean you have to use it. The 7mm Rem Mag has plenty of shoulder.
7mm Rem Mag brass has a bit more case capacity.
Logistics of the established 7mm Rem Mag are hard to ignore when it comes to brass availability.

I have a Win Mod 70 with a 24" 1:8 Brux barrel and reload Barnes 140gr. TTSX's @ 3117 fps.
With my 7 PRC 22" 1:8 Proof barrel I run 160gr CX's at 3103 fps.
I built my 7 PRC and its suppressed and it weights 2.2 lbs., less than my Mod 70. I prefer to carry that now over my Mod 70.
If you want to run the heavier monolithic bullets I would recommended the 7 PRC over the 7RM. I like both of them...Cannot go wrong with either.

7mm Rem. Mag Christianson Mesa. Lights out. A little too much for Antelope. Use my .243 next time

Thought about the new 7PRC, but I don't see enough difference between them to make much difference.
So (and I know I sound like a grizzled, grumpy old %$ when I say this)...
"When I run out of ammo (or forget it) in _____ Idaho, I can run down to the hardware store and pick up a box of 7 mag. Can't do that with the new-fangled stuff..."

So I have a question because a co worker is contemplating the same thing. His current 7 rem mag uses either h1000 or reloader 22 with 175 partitions. What’s the Prc eat for preferred powder? Reloader 22 is rather scarce, h1000 we both have plenty of, but if the prc prefers powder that extremely hard to find then what’s the point?
My 7 RM likes H4831 over H1000. My 7 PRC likes H1000 as H4831 is too slow and you run out of case capacity on the 7PRC.
I have a new jug of N560 that I will try soon.

RL26 if you can find it. I wasn't impressed with H1000 with my 7prc. I had better results with H4831sc with both group size and velocity.
