RCBS DIE QUESTION???

[74man]

This has me confused: I have an RCBS Carbide kit for 357MAG/38SPL/357MX, P/N18215) and it has a Seater Plug for a 38RN/9MM/38WC( P/N 702833) included in the same Carbide Box in a separate plastic RCBS bag. This Seater Plug is also for a 38 WAD Cutter which is different than a RN plug. Also what is a 357 MX?

I also have a RCBS Carbide 9mm Luger/9x19/9x21 kit P/N: (20515) which also has a Seater Plug for a 38RN and a 9mm Seater Plug in the kit also include in a separate RCBS plastic bag???

Why do I have the same Seater Plug in each of these kits? Is one Seater Plug different than the other and I am just missing the why?

Both kits are Carbide Kits but I am sure that a 38 Case won't fit inside a 9mm die so why include the 38 Seater Plug with it? Does this Seater Plug also seat 9mm RN bullets using the 38 RN Seater Plug? I thank everyone for an answer.

The bullet diameters are only .002" apart..355 vs. .357. They should work equally well between the two.

Also what is a 357 MX?

357 MAX

The swc seater will work for any flat nose bullet in either platform. On the other hand almost every rn is different so good luck with that, I avoid them in every caliber

.357 Maximum is a .357 Mag. on crack.

If marlin made a 357 max I'd have one. The 350 legend just tries so hard
