Reloading Die question please...a current project it going to be chambered for the 7x57Rmm caliber.
On Midway's site they have 7x57mm Mauser reloading dies...same cartridge sans the Rimmed head..so can I can use the 7x57mm Mauser dies for my Norma rimmed brass? Online search doesn't turn up any 7x57Rmm die sets. I appreciate the help...thanks...larryd

FWIW, some years back I ran into a guy at a local range who had a drilling chambered in 7x57R. He told me that he loaded his own ammo and used plain old 7x57 dies. Don't remember if said anything about the shell holder he used. I bet a phone call to RCBS would get the definitve answer to your question.

Iazza,

No problem here.

I have a set of RCBS 7X57R Dies and here in Europe Dies for Rimmed cartridges are appropriately marked with the "R" designation.

But you DO NOT require a "R" or Rimmed Die Set for reloading Rimmed and Rimless cartridges.

I use 6.5X57, 7X64 and 8X57IS RCBS Dies Sets to load the 6.5X57R, 7X65R and 8X57ISR cartidges - it's just a matter of using the correct shellholders for the Rimless/Rimmed cartridges and adjusting the Dies correctly to your press.

If I was in the States and confronted with the issue of specal ordering an EXPENSIVE set of specialty Rimmed Dies for loading cartridges like those mentioned above - I'd just pick up a set of vanilla-flavored, available everywhere, rimless Dies and be done with it.

There are though, cartridges where this inexpensive option isn't available, 9.3X74R as an example.

7 x 57 (R) and 8 x 57 I(R)S - ok, but I am NOT sure about the 7 x 65 R: there IS a Millimeter difference, either in case shoulder lenght or in neck lenght to the 7 x 64 !!! And as BOTH are expensive, buy the correct one.

Use a shell holder for .303 Brit or the belted Magnum case head ( Lee # 5 or RCBS # 24 - that´s from memory, so please check! ) for the rimmed cases.

Thanks guys...I appreciate the info...an RCBS #7 Shellholder (.303 Brit, 30-40 Krag) and a 7x57mm Mauser FL RCBS FL die set are on the way...now I have a 60+ day wait for a 7x57R reamer I've ordered and I'll go bang!...thanks again

Armenius.....

Correct; you are NOT sure - I am.
