Once again, it depends on your use. I prefer the 280AI due to the lighter rifle and less muzzle blast. I believe the 280AI will also serve you longer.
That being said, the 7mmRM is an outstanding cartridge. It can be pushed slightly harder.

I am shooting a 7mm RM with 180s at 3000 fps.

I have both. Personally, I think many people get a 280 AI and go to extreme lengths to try to get magnum performance out of that cartridge. The 280 AI is a great cartridge, but it won't quite achieve magnum level performance, if that is what you're looking for.
I think you would be pushing a 280 AI VERY hard to achieve what you're looking for.

My 26" rem. 7mag + brake will out shoot 3 different 7PRC rifles. 8 in. Twist 1/2 " @ 200 yds that's velocity and accuracy and vel. My 280 ack with same bullet is alittie slower @ 2990 fps.7 PRC........ only because someone else is going to say that. Even though the OP didn't mention it. The 280 AI is just a performer and will meet your parameters. No need to look further. Still I'd go with 7PRC!
With lighter bullets, the 280AI can get there. But with 175gr & up, the 7mm RM is not reachable.

Well, the rifle quality should be excellent!

Great thread but interesting in that some have both and report, where others do not and just opine.
I have both.

24 inch Ackley won't get you 2950 unless it's a fast barrel. I shoot 175 Berger Elites out of my AI. 2960 fps. I wouldn't chase a number like that with the 180s. You'll end up disappointed. Accuracy, pleasant shooting and efficiency I'd go 280 AI. Oh wait, I did! I gave my 7 mag to my son and sold the 7 PRC.
I do not like this cartridge or that cartridge discussions. I have 5 different 7mm rifles - but no AI. So not needed but not having one would drive my decision to keep filling out the family horizontally I do not typically buy different rifles in same caliber - what I call vertical purchasing. Not true for 270's though. So AI based on not having one. Sure kind of a dumb reason given your parameters that others smarter than me have given reasons for. But I do love learning from all of you. Awesome stuff.

7mm rem mag and 7mm PRC are the same case capacity but you can more easily use longer bullets in the PRC. A 280AI is going to have the same issue with seating long bullets.

Years ago, I built a truck load of 7 mags and a wheel barrel load of 280 Ak Imp, if you're into hot roding at all, go with the Mag. I had a few of the guys bring their 280 back to punch it out to 7 mag, kind of a pain as you now need to open the bolt face and tinker with feed rails. With all the new powders and high BC bullets available today it helps to have room for powder. You don't really need the speed with the range finders available, but after years of varmint shooting you can easily see the advantage of high speed in the wind, if the bullet gets there quicker the wind has less time to push your slugs around. Sure, your barrel won't last long, but life's too short to hunt with a boring rifle.
Not the real question, but what is IDFG doing?
