400 CorBon Dies

[mktacop]

Can anyone tell me if any of the 400 CorBon dies do a roll-crimp?

I'd really like to roll crimp these rounds to help prevent any bullet set-back, but can't get a definitive answer on this question. Any help would be greatly appreciated.

It is my understanding that Lee now has a rifle type FCD for 400 corbon that will do what you want. Do not confuse this with the pistol type FCD that is horrible with cast boolits.

Thanks Moonie. I have the Lee FCD for 400 CorBon, but it doesn't do a roll crimp.

I can't imagine you need more crimp than a rifle style FCD can put on a boolit, I've seriously deformed jacketed bullets with them before.

I got my set before Lee came out with the FCD for it, never had an issue with setback using the crimp in the seating die.
