A 7mm RUM case is larger than a 28 Nosler. So by definition that should make it more powerful. I doubt there will be much real difference between the two with normal, 24"-26", barrel lengths. You are limited on how much gas you can flow thru a hole at a certain pressure. If you look at all the existing load data it appears those limits on a 7mm start somewhere around 7mm STW capacity. The case capacity of a 28 Nosler is practically identical to a 7 STW.

There are a lot of variables such as recoil, barrel length, etc that have not really been addressed by the op. Without particulars I can say from my experience that there is no replacement for displacement. The larger the diameter of the projectile the more effect it has on the animal. The best elk cartridges begin with the number 3. I also do not believe there is such a thing as over gunned when it comes to hunting big game. So if it is just a choice between 30 or 7 with no other specifications, I have to say the 30 will do it better.

The 7MM RUM has ~108g H20 while the 7.21 (.284) Firebird Lazzeroni has ~ 120g H20.
The 7.82 (.308) Warbird Lazzeroni has ~127g H20.

Haha nicely done Feenix.
gun)Come to think of it, I wonder if anyone has done a 7-378 weatherby, seems like it would be good with the 195s and higher weights that are coming out

Yeah, I looked around and came to that conclusion, just not a cartridge you ever really hear about, and now I know why
7MM Allen Mag is based on .338 LM and he was launching 200g ULD RBBT Wildcat Bullets out of 30" barrel at 3300 FPS.

Yup, I'm fully aware of Kirby's creations... How about the 50 Allen Tactical and the 510 Maximus Feenix?

If your only hunting up in No. Idaho I'd get a 280AI and be happy. Heck I'd have no problem with the 7-08 for that matter. If you think you'll be shooting animals beyond 500 then you may justify more than an 280AI. Just my opinion.

I agree. .280 AI an excellent cartridge.

Right now as it stands the two that I find stupid awesome are the 28 Nosler and 195 Berger and the 30-338 Lapua with the 230 Berger, those are my two favorite top ends for both though a 7 Norma Norma mag would be interesting!
