I know this is deep in the woods, but will a shoulder/neck bushing for a 280AI work for a 7-08AI? Of course the manufacturer says absolutely not, but if you look at the drawings I can’t imagine why not. I understand their liability in saying otherwise.

This is for a SAC modular die. It’s a do all die for whatever cartridge family it is, meaning I can load .243 or 358 or 7-08AI simply by changing the bushing.

This may be the deciding factor to finally jump to the AI. I already have copious components to make it happen.

[/color] does anyone have both the SA and LA SAC die so you can confirm the OD of the bushings are the same?[color:#FF9900]

I would think so, but it’s outside my wheelhouse.

I'm showing both shoulders are .454" wide. The AI has the same shoulder angle, and both are 7mm. So, it should work.

When I formed my 300 Win Mag down to 7mm/300 WM, I used a standard 7 Rem Mag die. I set the 7 Mag die out long, and sized the brass down to 7mm and prepped them from there. The 7 Mag and 300 WM have the exact same shoulder angle and dimensions. Kind of the same thing you are doing.

I would think the lengths would create more problems for you than the neck/shoulder but I don't have one of those dies to know for certain.

Neck O.D. for 7mm cartridges is only going to vary based on brass neck wall thickness.

I move bushings around all the time.

Measure a loaded round case mouth O.D. and subtract .002", that's the bushing I need. The same bushing has been used on 7mm-08, 7mm-08 A.I. .280 A.I. 7mm Rem Mag and 28 Nosler.

More importantly .280 A.I. is long action, 7mm-08 A.I. is short action. How you gonna FL size a long action brass with a short action die?

Think he only wants to move the bushing from one die to next.

Correct. I have the Winchester die that’s currently sizing my 7-08. I’m wanting to put a 280 AI blushing in it for 7-08 AI. These bushings do the neck and shoulder.

The die is essentially a body die. The bushing does the shoulder and neck.

I have the same die set with bushing for the 6.5 PRC and am getting ready to play with the 25/PRC so that was my plan to just get a couple of bushings and see what works.
Don’t see why it shouldn’t work fine.
