Hello chaps
I want to make 7.65x53 Mauser (for the Argentine and Belgian Mausers) cases from a more available calibre. I tried using a Lee 7.65x53 full-length sizing die on trimmed 30-06 cases, but the resulting cases wouldn't chamber. I contacted Lee Precision and they said that full-length sizing dies are not designed to form the desired calibre from a different one, and I also found that a few others had this problem caused by the Lee die not pushing the case shoulder down far enough.
Looking for a solution, I found one reference to someone using 308 cases which are a little too short but could essentially be fireformed to become 7.65x53 - link here: https://www.thehighroad.org/index.ph...entine.675310/
(final comment)
My question is, has anyone else tried using this method with 308? Does it work, or can anyone suggest another solution? I'd rather not purchase the PPU brass if I can help it. I'd also prefer not to purchase any more dies. Any help is much appreciated.
