Thread: Is there any difference between 280rem and 270win federal brass once its sized?

will the internal volumes and weight be on par?

will the difference be noticeable?

lets throw 30-06

cheers

Very close 280 a touch ahead.
3006 touch ahead again

what do you mean touch ahead?
will they even out over time, ie after the first fireing?

In water capacity I mean

.280 has the shoulder further forward

will they all even out after the first load

?

I would say not

If you try size the necks of .270 brass to .280 and then fire them you'll have .050" excessive headspace

I do the 270 to 280 conversion all the time with Fedral cases. You have to anneal the 270 case, run it through 30-06 dies, anneal again, and then run it through the 280 dies. Weird looking case until fired. If I trim my converted 270 fedrals and 280 's the water capacity is identical. Hope that helps.
