Shell holders

[freebird63]

I recently aquired a custom built 280 Ackley Improved, included with the gun was a set of Lee full length re-sizer dies and in the plastic box came a shell holder. Also included were some brass. Some of the brass was 280 brass and some was 30/06 brass. My question for anyone out, does it really matter if the shell holder is for a regular 280 or a 30/06 or does it have to be for a 280AI
Thanks a bunch

They are interchangeable

There are many cartridges today that originated with the 30-06 case. It has a .473" casehead.
When you stand a 30-06 next to a 280, you'll notice they are the same case -with one necked down to 28cal. A 260, 243, 6br, or 22-250 are the same 30-06 case formed shorter and necked to cal.
Same .473 head shellholder for all

These are designated with a reference number:

And it is indeed. And a chek of the shell holders for the cartridges Mike listed, and many others, will show they share the same shell holder.
