I just re-read Al Nyhus' excellent advice on case forming for the 30BR and have a question regarding the one step neck expansion method.
I've previously been using Sinclair expanders in multiple stages but I've seen the light and want to go over to the one step method. I bought a Redding tapered expander button but don't think I have a suitable die to put it into.
Al says, "this button can be used in any Redding die that has a large enough inside diameter to accept the BR case without any case-to-die contact".
Well, the closest I've got is a type-S FL 308 Winchester die and although it works, it's also sizing the body of the case at the same time. I can't imagine it's sizing it too much since the bottom half of a BR case should be the same as a 308 and it certainly doesn't touch the neck or shoulder however, it just doesn't seem right.
Anybody want to suggest a specific die that is the best one to use for fitting the 30cal tapered expander into for 30BR case forming? A part number would be great too :thumb:
Thanks,
