Caliber? Along with 300 win mag, 30-06, etc. locally at least. Maybe I'm wrong, I'm an archery guy commenting on something I'm obviously clueless about?

Caliber is diameter of projectile
Cartridge is the launch pad

Well it intrigues me. Already have the 6.5 and 300 so May as well get a 7. Already reached out to my smith and will be able to shoot one while on an upcoming hunt so I’ll get to see what it can do.

Just bought a 7PRC Proof Sendero pre-fit. Just waiting on a defiance anti action to get back in stock and I’m on my way for my first magnum build. Pretty stoked. Going to try and use an XLR Magnesium chassis too.

Bring on the memes!
I'm not typically one to jump on new cartridges, but this one is going to be awesome. I never even bought a 6.5CM until 2019 or so.

Already ordered a couple boxes of 7 PRC from midway.

That would be a better round than the current 6.5 prc/270 win round.

What would make it "better"?

 

[Keener22]

The shelves at Cabelas suggest 270 and '06 ammo are in high demand.

Theoretically, if there’s 270 and 30-06 ammo on the shelf, but let’s say no 6.5CM, 6.5 PRC, 300 WM, whatever….doesn’t that mean the 270 and 30-06 are less popular?

…theoretically of course

Here is a chart I made in excel showing ENERGY of the following rounds:

-7 PRC 175g ELD-X (factory load using their published data)
-300 WM 178g ELD-X (factory load using their published data)
-7MM RM 162g ELD-X (factory load using their published data)
-300 WM 210g Accubond LR handload (used data from Nosler reloading data) Muzzle Vel. 2815 fps

The 7 PRC and the 300WM handload have almost identical energy from 400-1000 yards, with the 300WM starting higher (BC of the 7PRC trumps it)

Interesting data. In my opinion, the 7 PRC is really exceptional past 400 yards, under that, it's nothing special. The biggest thing it will have less recoil than the 300WM, so that is appealing.

The labels are on top of the chart.

Yep. That’s exactly why I’m choosing the 7PRC for my first magnum build. Moving from a 308 and seriously looked at a 30 cal magnum but once this round was introduced I just didn’t see the point in having more recoil for similar results. I’m also a recoil sissy so that definitely is the biggest driver for me.

Pretty cool comparison.

Now, what about the 300prc with factory 212 ELDX...

 

[Keener22]

Yep.

Yep that just sold me too. Probably going to look at the 20-22” barrel range, to add a suppressor. Should help my mushy shoulder with the recoil.

Just bought a 24” proof prefit as the shorter ones were sold out. I’ll be running a TBAC Ultra 7/9. I’ll have to see if that ends up being too long and I guess I could always have the barrel cut down.

Man I'd hold off and get a shorter barrel, I was running a 24" with an 8" can and it was way to long for hunting, CF shouldn't be cut down either.
I wouldn't go longer than 20" suppressed

Thanks for the input. On what situations was it too long? I’ll have a folding chassis so when I hike it’ll be 12” shorter when folded.

By that logic you should just shoot 165s out of your 30 cal and not 180s

Can you think of a single situation where, if a 165 won’t do it, a 180 will?

Realistically, now.

Youre right, call every ammo maker and tell them they are making a mistake by making 180 gr bullets

Good comparison but clearly biased by hornady pumping up their own cartridges. That's not to say that the 7 PRC #'s wouldn't stack up real well if done neutrally, like when hornady compares them to their 6.5 and 300 PRC cartridges.

The idea that a 7 PRC with 83 gr of H20 capacity somehow pushes a 175 gr .284 eldx faster than a 300wm with 92-95gr H2O capacity pushes a .308 178 ELDx - anyone who understands how this stuff works can can see there's some gamesmanship going on. Add to that my personal experience with 300wm Precision hunter 200 eldx (which is a better comparison to 175 7prc) had actual muzzle velocity of 2950ish which is about what they list the 300wm 178 precision hunter at.

Do you think it could have anything to do with BC? Never dug super deep on all this stuff, but I’m sure true numbers will come out eventually.

Why would I do that?

Obviously many people believe that 15/7,000ths of a pound difference is meaningful.

Just like all the overlap in cartridges. What does the 6.5 CM do that the 6.5 Swede doesn’t?

Answer: sell more rifles.

And in the case of the 7 PRC, what does it do that the plethora of 7mm cartridges already in existence not do?

Same answer as above.

I’ll stick with what I have but I hope gun/ammo/component manufacturers make a ton of money.

And you didn’t answer the original question.
