why in the world would anyone want to do that? Get a 7mm rem mag, and rock on at 3150fps with 140gr barnes. Don't have to worry about fireforming, sticky ejection. But I guess Larry is big on it, so your all over it.:s3:

The belted mag is definitely easier but i also like the AI. My buddies will throw a 140 gr tipped tsx at 3400 +

Nosler 140's in 280AI are about 3150, according to their numbers. Same bullet offered by Federal in 7mmMag goes the same speed. I believe Kimber had considered the AI as a factory offering awhile back, but to no avail. Nosler is pricey at $52/box. Some like Budweiser, some like ShinerBock.

If you like something different.

If you reload, you can kick a 7mmRemMag up over 3300fps with 67gr of RL22. I have seen it myself. 3150 is about all the 280AI will ever get up too with 4gr less powder of RL22. 280 AI is a loose loose situation. Unless you want to tell people you got a 280AI.

Doesn't 140 factory ammo in a .270 WSM go over 3200. I know I've heard reloads in a 140 going over 3300. That sounds as good or better than your 7 MM.

I mean certainly either will take a deer, antelope, etc...and be pleasant to carry a lightweight rifle in the mtns, but in elk country with grizzlies, or brown bear country, I'm thinking you might need to take a .300mag or larger as a minimum in which case, who wants to shoot a magnum in a lightweight setup, so in those situations are you stuck carrying a heavy magnum?

I feel the same way about Grizz :arms:

Here is my 7MM Rem Mag - In Stainless 6 5/8 lbs.

Both good mountain rifles IMO or maybe I should just say; works for me !

In reality, anything between a 260 and 300 Win Mag is capable of what he's looking for. Biggest boom out of the smallest package would fit the bill. Between his two choices, I'd go 270 WSM.

But, he's the one paying the bill.

Both a 7mmrem mag and 280AI would share the same action. Both COL's are close.

Now talking about a short mag, its a different animal all together.

I was just questioning why you thought the 280AI was such a winner. Just curious is all.

I have went down the AI road with other calibers and came up short. In the end, if I want more velocity, I won't be blow shoulders out and dealing with straight walls for a "hunting" gun anymore. Target, you can do what you want, it doesn't matter.

I don't know if its a "winner", but maybe an option. I've only read about it on this site and a few others. I understand it as being a decent cartridge. Your discontent is interesting though. 7mm WSM seems to be turning into a dinosaur, leaving its cousin 270.

.270 winchester.... or .25-06 remington ... thats right... the non-magnum... i know i know... flame away... but I just see no point in a magnum...
