if you really want something cool, do the 7-6.5prc or whatever that cartridge is.

6.5prc necked up to 7mm. Will be plenty of gun for whatever you are doing and can be run on a short action.

Orrrrr split the difference on a 6.5-7prc. OP I'd just starting to reload too so that's really a great option.

Going down in capacity with the same 7mm bullet doesn't make sense but stuffing a 6.5 in there does!

6 creed does everything you are asking for and then some.
From a pure hunting/killing gun standpoint… What functional advantage does a 6 Creed, say shooting 103 ELDX or 108 ELDM, have over a 22 Creedmoor shooting say, 80 ELDX or 88 ELDM?

Let’s say both are setup identical with 18” barrels. Input 3100 for the .224 and 2850 for the 6mm for the calcs. 10 MPH full value wind. 5,000 ft DA.

At 800 yards the 103 ELDX is 1,750ish FPS. 700ish ft lbs of energy. 5.6 MIL Up. 1.4 MIL Wind.

At 800 yards the 108 ELDM is 1,800ish FPS. 780ish fr lbs of energy. 5.4 MIL Up. 1.3 MIL Wind.

At 800 yards the 80 ELDX is 1,900ish FPS. 650ish ft lbs of energy. 4.6 MIL Up. 1.3 MIL Wind.

At 800 yards the 88 ELDM is 2,000ish FPS. 800ish ft lbs of energy. 4.4 MIL Up. 1.1 MIL Wind.

Free recoil energy in an 8 lb gun shooting 88 ELDM out of 22CM is around 9.5-10 ft lbs.

Free recoil energy in an 8 lb gun shooting 108 ELDM our of 6CM is around 11.5-12 ft lbs.

Mostly that one is legal to hunt with in my state, the other is not. I guess I should have added I'm a CO resident, and it's my primary hunt state.

6 creed is a gateway drug. The op can't wrap his mind around using a 7mm for elk yet, extremely unlikely that he drops to a 22 cal.
To be fair... I never said I couldn't wrap my head around using a 7 for elk. I said this gun build was primarily for deer and speed goats, and for hunts where I don't want to pack my 300wm around. And 22 isn't legal in my state, so there's that...

I don't disagree. But for me, like the OP, it's a state legal thing. In WY a .224 is legal for deer/pronghorn, not elk. 6mm is legal for elk.

I think you’ll love a 7mm - it’s a great combination of shootability and game smacking performance. I was a 270 kid, but hunting next to a close family friend and his 7 mag, it didn’t take many years of watching animals fall side by side, that I was borrowing his 7 mag. Anything the 7 mag can do, the 280ai can do one hundred yards closer, and the 7mm-08 can do 200 yards closer (or is it 300?). There is zero chance of 7 Rem Mag ammo ever being at risk of poor availability because there are so many of them out there. Nothing wrong with the PRC, but at 500 yards it’s not doing anything special. Beware of PRC ammo - Hornady has been cut off of RL26 powder, which the PRC was designed around, so right now only Federal ammo will reach full velocity - great Hornady support is not a big selling point.

Even my 5’2” first wife watched the difference on game between her 243 and my 7 mag, and she wanted one for quicker kills. When you’re taking a lot of game next to someone, it doesn’t take a lot of experience, age, or dozens of animals to see the superiority of the 7 mag over smaller cartridges. Teenagers see it, little cute gals see it. To 500 yards simply using a 160 Nosler Accubond or Partition will kill everything out west with boring regularity. No need to compare autopsy photos with friends to convince each other it works, or scratch your head when friends have weird results with some other bullet. All the marketing hype from Hornady falls on deaf ears if what you’re shooting simple works, every time, for everyone you know.

My 280ai rifles hold enough velocity and fpe to kill elk to 1000 yds.

I’m a big fan of the 280ai - don’t have one yet, but will one of these days. I doubt any animal would be able to tell the difference between it and a 7 mag.

I’d love a 280ai. I think it hits the sweet spot for standard length, standard bolt face rifle.

My hangup is I have a 708 and a 270, and there’s just not enough difference to justify it.

The 270 with some of the newer, fairly heavy bullets, is hard to beat and very similar to the 280.

My 708 I call my 270 short. It can throw 120s at 3250, and you can throw 160s with good enough speed to kill anything, as well, inside of 400 yards. The 150eldx is touted as the “do-all” for the 708, and it looks that way on paper to me. The 120BT is a heck of a killer and I’ve still got lots to shoot, before shooting a different recipe.

Most of my kills are between 200-450, and either will do.

To the OP get what you want, that’s part of the fun!

I’m glad to see more sleek 270 bullets - the numbers between it and a 6.5 PRC are neck and neck, at least to 500.

I built the perfect 7prc rifle. 18" Proof barrel on a Tikka action.

I put it together and shot it one day then took it back apart and am shooting a 223. It's more mustard than I'm wanting, so it's gna be for sale very soon.

All that being said, trust the internet on this one. You will not regret going 6cm. If you do, someone here will buy it.
+1. I too built a 7prc, put 10 rnds downrange and took it apart. It now wears a 25-6.5 prc barrel. Should put 134g pills downrange at 2950 instead of 180’s. Lose some bc .401 vs .325 but with 30% less recoil.

This might make my kerfuffle worse, but hear me out...

I am simultaneously jumping into reloading (300wm) and planning my next rifle purchase. I have committed to one of the 7mms, 280ai and 7prc chief among them. Problem is, if I read enough here on the slide, or watch a few YouTubes, I talk myself in and out of each, among others.

What do I want out of this new gun? Glad you asked! Desires and considerations in my mind are as follows...

-Dedicated deer/pronghorn/target rifle with a small chance of elk, if the hunt is serious enough to not warrant packing my #10.5 300wm. 500 and in for hunting, steel to however far I'm feeling frisky for. 24" or shorter barrel, ideally #8(ish) scoped.
-Reload friendlier for components. Cost is included. Seemingly, 280ai would be "cheaper" given the smaller case capacity, but 7prc seems to have more/building popularity for case availability/support.
-280ai > 7prc as it's lighter recoil, equals better barrel life and more fun to shoot.
-7prc > 280ai in shooting heavier bullets. I like heavier bullets, but I also have a 300wm for that...
-7prc is faster. See point above
-280ai is cooler (less mainstream, tickles my fancy)
-If I'm gonna reload, why don't I consider "xyz" other 7mm super secret/cool/awesome/new/weird/mind-blowing cartridge?

Mental masturbation? 110%. But I have time while I save up for whatever I decide, and enjoy the conversation and/or sarcastic feeler hurting comments. Cyber penny for your thoughts of you're willing to share.
Where did this guy ask for a 6mm? It’s so obnoxious the need for the clan to jump on every thread and regurgitate what they’ve been sold…

Anyway…

If you reload the 7saum is a sweetheart of a round. 180 eldms are killers, get them started around 2750 in a 20” barrel and they just keep going and going and going. Recoil is super manageable with a suppressor and spotting shots isnt difficult assuming you’re using a reasonable magnification.

500 yds is a mighty long ways, in 30 years, haven't had the need to shoot at a live animal or a second shot follow up from further than 400. There are two schools of thought, in a general sense setting up for over 500 yards ("long range") or staying under 500 yards ("closer range") by closing the distance. I am an old dog so under 500 yds is where I am at for my hunting and the area I hunt. But in all honesty, if I threw money at a rig to go beyond 500 yds, I have confidence that I'd do the things with cartridge selections and practice to be successful at that range too. Much of this has to do with what folks are brought up doing and so much more is available to us as hunters in making decisions in this era.

I’m also old school and conservative with distance. I’ve always limited shots to under 450 - if I could get to 450 the shot is pretty certain shooting over a pack, and in calm conditions 500 has been reliably doable. This year I’ve been working on extending that to 600, but many days and situations are limited by wind, so I’m not willing to let myself think 600 is a new max for normal conditions, but rather a max under calm conditions. It might only be 20% farther, but reliably hitting a 10” paper plate can be more than twice as hard that far out - I’ve had to upgrade the range finder, increase scope magnification from 6x to 8x, and using a rifle a few pounds heavier. Teaching my nephew to understand his max range has been fun - some days I don’t know what that kid is thinking. Lol

What's your fpe at that range/your cutoff for elk?
My 280AI rifle loves Federal 168 Berger loaded ammo. I'm still at 1800 fps at 940 yards at my typical DA where I hunt. Same parameters with my 7mm PRC shooting the 180 ELDM factory ammo and I'm at 2076 fps at 940 yards. That rifle/bullet hits 1800 fps at 1320 yards. Just information. I prefer the recoil from the 280AI over the 7PRC. The 280AI is a much lighter rifle but I don't lose my sight picture like I do with the 7PRC. I would build another one in each caliber as they are very accurate.

The 7mm-08 would fit your desired use well. It will shoot the 160 and 168 grain bullets well and keep you at velocity/energy numbers way past 500 yards with a 22" barrel.
