How to measure and identify 280A.I. brass?

[MNbogboy]

A new red state, but have to get all the union guys in the mines to see the "light" and forget the identity politics that the libtards are invoking on them. Thanks to our nations current leadership they are going full speed ahead right now. The southern part of the state should join up with California and New York practice communist socialism on their own!

I fully agree with you

What I bought is stamped "Nosler, 280 Ackley Improved". Why would Nosler have different case capacities for loaded ammo and new unfired brass? From a manufacturing standpoint it doesn't make much sense to buy tooling to make two essentially identical cases with the slightest of differences. I am not saying you are incorrect I just wonder where the information came from for my own curiosity.

I'm using Nosler brass for my Spec 280AI and new Nosler brass I have it measures 2.1870" to start of shoulders. Hornady making brass for 280AI also loading ammo.

I also shoot 35 WhelenAI,243AI and 222AI. I fired form those using factory brass and I can do same using 280 case in spec 280AI. Sure case is shorter but they didn't trim case as that missing length is in case body.
When I fire form the Whelen I got very little increase in case capacity. I
look at Spec 280AI maybe have little more case capacity.

My way of thinking is that this is the only way to form brass. I've got some Norma 270 Win brass on order. I plan on annealing the brass first, then hydroforming the brass from there. I feel that is a wildcater's best option. I thought that it was going to be a messy proposition, however after watching the video, it appears to be relatively a clean job. I think Whidden quoted $175

I have one of John's product and they are awesome. Just a recommendation, because you're going to do couple of pounding forces or so, you might consider a separate press for your hydro-forming from your regular reloading set-up.

The pain of fire forming AI brass does get old. Having both 257 Bob A.I. & 6.5/257 Bob A.I. with multiple barrels in each caliber it gets to be a hassel.
The Whidden forming die would definitely save the barrel wear of the first firing. However, the first firing of a new batch of brass can be used for 3 things;
A) break-in, sometimes it takes 100-200 rounds to come up to speed.
B) use for initial seating tests prior to OCW and velocity ladders.
C) actual workup of non-fireformed loads. For "emergency" use.
We must keep in mind it takes 2 or 3 firings to fully "stabilize" the brass dimensionally before final load work is completed.
Just my .02,
Randy

The Nolser 280 AI brass I have shoulders are round and dia at start shoulders isn't fully formed. You use Whidden die but for shoulders you need to FL size.

Hornady been making one for long time
