The Best Overall Elk Cartridge is…

The 280 AI???

I’ve been going down the rabbit hole on elk cartridges for years now—7 PRC, 7 SAUM, 7 SS, 7 Rem Mag, .300 WM, short mags, the whole thing.

I decided to ask ChatGPT what is the best elk cartridge with the following criteria (see below) to try and get an unbiased answer.

ChatGPT criteria:

•Western/Utah elk hunting terrain

•I value shoot-ability

•Maximize hit probability and minimizing recoil while still fully elk capable

•Penetrates sufficiently

•18-22” barrel so it can be used with a suppressor

•2800-3200 Muzzle Velocity

Over and over the response was 280 AI for various ways of asking which cartridge was best or ideal for elk.

“The 280 AI gets 90-95% of the 7 SAUM/7 PRC performance with: less recoil, less muzzle blast, better barrel life (double the life of 7 SAUM), easier shooting characteristics. It’s very forgiving to hand-load, feeds reliably, and is less finicky than short magnums

Most importantly: it optimizes the whole system. It balances recoil, penetration, hit probability, rifle handling, follow-up capability, and practical field effectiveness.

The internet tends to obsess over energy numbers and wind charts, but once you start thinking in terms of actual field hit probability instead of ballistic fantasy, the equation changes. Recoil, rifle weight, suppressor balance, spotting impacts, fatigue, and positional shooting matter more than squeezing another 100–150 fps out of a cartridge.

That’s where the .280 AI shines.

You get near-magnum external ballistics without full magnum recoil. With modern 160–175 grain bullets, it has all the penetration and terminal performance needed for elk while still being manageable enough to shoot well from real hunting positions.

That’s the key:
A cartridge only helps if the shooter can fully exploit it.

A lot of guys shoot a .280 AI better than a 7 PRC or .300 mag, especially from awkward field positions. Less recoil means:

  • better natural point of aim maintenance

  • less anticipation/flinch

  • easier spotting of impacts

  • faster corrections

  • more confidence

  • more practice

The other thing people overlook is efficiency. The .280 AI works extremely well in practical hunting rifles. You can run a 20–22” suppressed setup. It doesn’t need a giant barrel to perform. It suppresses better than the bigger magnums and still carries excellent wind performance out to sane hunting distances.

Could a 7 PRC beat it on paper past 700 yards? Sure. But inside realistic hunting distances, I think the .280 AI sits right in the sweet spot where ballistic performance and shootability overlap.”

Agree or Disagree with the ChatGPT assessment? I certainly wasn’t expecting this recommendation, but I really like the breakdown it gave of why it picked the 280 AI.

The 280AI has 2X the barrel life of the 7SAUM? That seems odd. Last time I compared load data for both, with light bullets the SAUM had a minimal increase in powder capacity, but when you go to heavy (which is what you’d use for Elk), they are exactly the same powder charges and velocities.

I consider them equals. Yes, they are a step down from 7prc/7RM. You typically will have a better magazine capacity with the AI, and a shorter action with the SAUM.

Have more than one example of each, and love them all. My AI’s are loaded with mono’s and my SAUM’s use cup&cores, purely by coincidence.

Different Hunters prioritize different things. These two are great middle of the road approaches between the big Heavy Hitters and the super lightweights. However I’ve heard more than one elk hunter say they just want to have absolute massive penetration, bone destruction, tissue destruction and therefore they believe in using the 38 calibers or bigger. Of course there’s the whole side of the internet right now that is talking about how you can kill elk with 22 or 24 caliber bullets, and they are prioritizing ease of shooting

Ha that’s funny about the barrel life. I did just plug that in again by itself and it spit out the following, so not sure why it said it was double in that response summary.

  • 7 SAUM: ~1,000–1,500 rounds before noticeable accuracy degradation (especially if run hard)

  • .280 AI: ~1,500–2,500+ rounds depending on pressure, barrel quality, and firing schedule

Like you said, a lot depends on how hot you load each of them, but want to make sure the correct information is being put out, thanks Carter!

I know the Internet will never agree on “best”, but it’s always fun to debate stuff like this, especially when ChatGPT picks an unexpected cartridge. I thought for sure it would spit out the 270 Win or 6.5 PRC. Tried to pick the criteria I thought would appeal to most elk hunters.

Yeah. I found a reprint of the Hornady data. They say for hot loads, the 280AI is 1200, and with mild loads it’s 2000. They don’t list 7SAUM, only 300SAUM, which is 2000 for hot loads and 2800 for light So the 7 should be less.

I’ve become a firm believer that the 30-06 and its family are the best compromise cartridges around. And that’s why they have been so popular.

I think it’s probably 7 SAUM or 280ai or 6.8 western. But I’m experimenting with just a light accuracy load in a 7 prc.

I’m doing builds of all of these this year and I’m gonna let them fight it out :grinning_face:
