New brass has already been annealed so there is no need to do it a second time.
If it's once fired brass. Then yes

Figured I’d update this thread, I turned a mandrel on the lathe. It’s just shy of 0.400” od, it ended up at 0.397” after polishing with wet dry paper so good enough. I used it in my Lee universal decapping die, was a successful first attempt to neck up.
I have some once fired 30-06 cases my neighbor gave me for this experiment and some .270 range brass, ironically I just gave all my 30-06 brass to a buddy.
30-06 necked up in one pass easily, .270 needed a pass with a .308 expander mandrel first. Then it was easy to make the jump to 0.397” on the second pass, I’ll probably use a .311 mandrel from either my .303 or x54r dies when I do the rest of the .270 brass I have. Necks were lubed well but not annealed for this first test, will run them through my 9.3x62 sizing die next so they just chamber in my rifle.

Here’s a before and after for the .270, far right case is a fired 9.3 from my rifle.

Ran it through my 9.3 die, L to R .270 to reformed 9.3x62
What makes you think a well made expander button turned on a lathe wouldn't be "the right tool for the job"?????The Lee mandrel die isn't exactly expensive. Nothing like the right tool for the job.
Good job bb

Cheers, one of the many fun parts to hand loading.
I think he's referring to my drillbit/press post, which is off the wall compared to BBills custom mandrel
nice work BB
hope you don't have trouble with the Lee die, I just messed up a sizer I bought used when I tried to adjust the decap/expander, the large threads on the locknut got all galled up, maybe to much torqu at some point idk, but now its JBwelded non-adjustable lol
Yes.
