460 mag shell holder

[lilguy]

I can shoot 45lc and 454 cas in it but I hear the corresponding RCBS shell holder
Is incorrect for the 460 mag. What's the correct holder to use in my old turret press?

 

[CaptHank]

RCBS #4 for the S&W 460 Mag.

Yup, 460 has a thicker rim, needs the #4.

Yup, 460 has a thicker rim, needs the #4.

I was under the impression it was the larger rim diameter that made for the different shell holder as SAAMI specs for rim thickness for both the .460 and .45 Colt are the same.

Yep!
You win the cigar!

.45 Colt rim thickness is .060"
.460 is .059"
Manufacturing tolerances are more then that.

However rim diameter is:
.45 Colt - .512".
.460 S&W - .520".
