35 Rem from 308
First, DO NOT buy 35 Rem cases on Gunbroker unless you have more money than Carters has liver pills. There are still plenty of places out there to get 35 Rem brass for 55-75 cents a case; NOT the $1+ that they're going for on GB. I have seen guys on GB pay as much as nearly $2 for empty cases! Crazy! Try kensbrass.com.
I load 35 Rem for my TC contender from 308 military brass. Bruce B doesn't exaggerate; I can have 50 cases ready to load in about 2 hours.
I decap, cut out the primer crimp, and ream the flash hole.
Next I anneal the case heads and necks with a handheld blow torch.
Then I full length size the cases through a Hornaday .457 bullet sizing die. I use my .50 Cal press because it has plenty of muscle for this job, but a Rock Chucker or similar press will do provided it is firmly mounted to a sturdy bench. The bullet sizing die will size the case all the way down, including the head. No bulging or trimming to deal with. Lube the cases well.
Then I run the cases through the neck expander, followed by the full length sizer die.
Next I trim the cases to length and debur the case mouth. One more visit to the neck expander and the cases are ready to prime and load.
Keep in mind the 308 sized to 35 Rem will have a reduced volume due to the resizing process "thickening" the case walls.
Once I fire form my cases I never have to size them again. Thanks to the annealing process and thicker brass, these formed cases seem to last forever.
Is the process worth it? I can buy 308 military once-fireds for 15-17 cents a piece...I'd say it is!
