I'm just starting out with this cartridge, and would like to use a Lee Factory Crimp die. Do I need a custom die from them, or will a .416 Rem Mag die work? I asked them, but they just said it works off the case length. If that were true, which it probably isn't, I could use the Rem die, since there is only .05" difference in case length. But it looks to me like the shoulder pushes the die up. Maybe I couldn't even get the fat Rigby case into the die at all. I 'spect someone out there knows the answer for real, and will tell me. Thanks in advance.
BTW, any other comments on loading for .416 Rigby are certainly welcome. I've ordered RCBS dies, Davidson comparator nose (may not need it), Norma cases, and a few different 400gr bullets.

Send an unpowdered seated round and $25 dollars to Lee and they will make you one.
That's what I did. I think it was about a 10 day turn-around.

rcasto,

Thanks! I'll order one.

An alternative is to cut .003 off the neck expander button on your drill press or order one that much undersize from RCBS or whoever. I do this on all my DGR calibers and combined with a powder that fills the case to the base of the neck you will never have a problem....

Thanks, Ray. I was planning to take some off, but I didn't know how much until you posted.
