280 AI custom ammunition

[rpowell]

is 280AI custom ammunition available yet? i know the brass is, but i do not see the custom ammunition yet. i was told by someone that nosler is already making the custom ammunition. if this is not true, does anyone know when the ammunition would be available?

The ammunition is being produced in house for the custom rifles, but it will not be released for retail sale until SAAMI gives it the final approval.

Any timing on when you will get the blessing from SAAMI?

Any news related to this yet?

 

[Glock Man]

From what I have gathered, SAAMI will be reconvening this fall. I would assume September or so. We should have the final stamp of approval then.

 

[JRH]

Any updates available on the status of the SAAMI meeting?

Any updates? When SAMMI does give the approval, how long would it be before ammo was available for purchase?

Thanks,

Joe.

I'll try to get an answer from Nosler on the status of the SAAMI approval for the 280 AI.

[JD338]

The SAAMI approval for the 280 AI will be in about two weeks.
More details to follow when they become available.

That is very good news. I'll keep checking back for more information.

Thanks for the status report.

That is great news...please keep us informed!

As an aside...can anyone confirm whether this ammunition is compatable with Kenny Jarrett's .280 AI chambered guns? (Or have some liberties been taken with the dimensions on Kenny's or Nosler's part that differ from the classic .280 AI dimensions?)

The 280 Ackley Improved case has a 40 degree shoulder.

Nosler is waiting on SAAMI to give the final blessing. Once this is done, it will be offically released.

JRH, there are no classic dimensions for the 280AI. Don't think Ackley ever did the 280.Rick.

Rick,

I believe in most circles it is accepted that the 40 degree shoulder is standard. My question was really a two part question, 1st I wanted to confirm that new ammo was going to be 40 degree, and second I wanted to confirm that the Jarrett dimensions were the same. (I know the Nosler brass chambers flawlessly in the Jarrett guns)

I currently load for three different 280AIs. One built by Jarrett's shop and two built by Carolina Precision Rifles. The Nosler brass works in all three but it will be after deer season before the loads will be worked up.Rick.

 

[JD338]

JRH,

The Nosler 280AI is a 40 degree shoulder. There is no standard since this is a wildcat cartridge but Nosler will have the standard once SAAMI gives them the approval. At that point, you can make comparisons to the Jarrett. You may or may not find that there are some minor dimensional differences.

JD,

Thanks for the info...I just spent about a half an hour with a micrometer comparing .280 AI custom loaded Jarrett ammo with Nosler brass. While I did find some minor differences, in general they seemed so small that I am not certain the differences would be meaningful without also taking into account the tollerences of the firearm through which they were being fired.

JRH

Any idea if these were the dimensions submitted to SAMMI?

 

[JD338]

JRH,

No idea what Nosler submitted to SAAMI. I would think what ever they have listed in RG #5 is what the went with.

JD338

 

[JRH]

JD,

The specs above were published in 2006 courtesy of Nosler. So I suspect those may have been the numbers submitted...

JRH

 

[JD338]

JRH,

I agree with you.
I hope Nosler will chime in on this soon, the suspense is killing me!

What are you loading in your 280AI? I'm using 60.0 grs RL22 in the Nosler case with a 160 gr AB and a Federal GM215M primer.
My best group measures .092" center to center.
