Attachment 324378 Sometimes reloading dies will not work for a particular cartridge. I found out after what I thought was a 32-40wcf Ballard target rifle. After slugging the bore came to find the groove diameter was .330" So maybe my newly acquired rifle was not 32-40 but maybe 33-40wcf !!! I owe marlinman93 a big thanks for his observation. My Lee Precision die set squeezed my brass way too small. Hit a corner of the sizer die with a file. It bounced off! Called Lee Customer Service. They were first class! Calvin from Lee's Customer Service was most helpful. He came back to inform me Lee uses 12L14; a free machining steel alloy on their sizer dies. I included a photo of me annealing the sizer die to a dull red. I buried the hot die in a bucket of sand. Came back a half hour later and dug out my soft die. I chucked it up in a collet and reamed the neck of the die to .351" and gave it a nice polish job. Now 30-30 WCF and 32 WCF cases form up nice to make 33-40wcf brass and accept my .333 cast and lubricated boolits. I will recase harden my altered sizer die. But for now I am as happy as a clam! My old Ballard shoots clover leafs at 50 yards!
