My new, still-in-the-box .280 AI.

Or .280 Remington. I really haven't decided yet.

Pretty!
What’s in going in?

 

[BuzzH]

AI...

CPO loves the AI in his Kimber. Given the cost and difficulty of finding the rounds vs my 06 I would say that while functional it hasn't really impressed me.

 

[MThuntr]

280 Sherman or similar

No downside in going 280 ackley unless you already have 280 dies

That's part of the quandary. I already have .280 Rem dies and a bunch of brass, so I'm kinda leaning that way.

You having a gunsmith chamber or buying a prechambered barrel?

Planning to buy a Rem/Age barrel, probably Criterion. I have most of the tools to install it myself. That's really what I wanted to do since I got interested in a build. Little by little, I've ordered things as I had the money. I have a barrel vise, an action wrench, a Timney trigger and a box full of the metal and hardware for the magazine and trigger guard. I have a pilar bedded Hogue Overmolded stock I'm going to drop it all into for now, but will likely look to change that out at some point.

Karl Feldcamp could make that bolt look better while you are deciding on a cartridge.

7.21 Tomahawk??

Is that an RR action? If so they are normally pretty true but almost all of them have little to no primary extraction but Dan at accutig is great to help fix that if you wanted to.
I’d use a good aftermarket recoil lug and you should be good to go.

.280 Rem all day. What ever you are shooting at and no animal will never notice the difference of only 150fps at best.

 

[Seamaster]

The AI version is a little faster, but for all practical purposes it is not significantly better than the regular 280 R. The AI is somewhere between the 7 RM and the 280 R in all thing such as velocity, powder requirements, and barrel life. Whatever floats your boat is the best choice.

You should probably go with the AI. It was your first choice and title of the thread. Although you'll be just as happy with the 280 Rem, you'll probably always have that feeling in the back of your mind that you settled. The cost of new dies and brass is minor when it comes to the "Dream Rifle". Go whole hog and don't look back...

Good luck on your build.

7.21 Tomahawk??

Had to look that up. Never even heard of it.

 

[std7mag]

Yeah, you have the wrong bolt.
And action.
Lazzeroni uses way high pressures. Upwards of 70,000.
They recommend only Lazzeroni actions, or Savage large shank.

I have (2) 280 Rems. Would love to AI one of them. But don't want the added expense of setting the barrel back.

Good luck on the build!
Keep us posted!

Where's the rest of it?

Sorry. It's going to take a minute. I have to spend a couple months squirrelling away some $ for the barrel. It's a pay-as-you-go project.
