So I've got almost everything together or on order for doing a 35x57R rifle I think, and looking for any information or tips and tricks that other people have on doing so. I've got a set of 35 Whelen dies inbound, I've got a .358" barrel blank, I've got 7x57R brass inbound (shoulder/neck look like they'll sit closer to where the dies will once trimmed). Obviously being a rimmed variation on the wildcat may present some issues, but it's necessary for the SMLE action I'm using so I'll worry about that as I get to it. How do people usually shorten the 35 Whelen dies for 35x57? I know being a rimmed cartridge the headspacing process won't be exactly the same as on the non rimmed wildcat, but any recommendations beyond just stopping and fitting every now and then for cutting the chamber without going too deep since the reamer is for a longer cartridge?
