M1A Dies

[Flinchrock]

Got some good advice about brass, now the question is about dies.

What do you folks think I should get??

Regular dies are fine.

The reality is that as long as you size the brass to SAAMI specs, it should feed, load, and fire well. Just don't expect too many firings from M1A brass. They will stretch like crazy, and case head separation is the common cause of failure. No avoiding that, regardless of sizing die.

DO NOT try to neck size only. That's only for bolt action guns, not for auto feeds.

If you have the knowledge, you could get the actual headspace for your gun, and then adjust the sizing die to that. But for most people, that's more fussy than is needed.

Keep in mind that "factory ammo" is sized to SAAMI specs.

Get the RCBS X-dies (regular ones as the SB dies are not needed regardless of what is said). With those you can get 16 - 20+ firings per case and will not have to trim at all.

With any of the regular dies you will get short case life (4 - 6 firings depending on load).

X Dies it will be.

I agree with the X-die recommendation. Make sure you understand and follow the instructions.
