Minkman.32/20 forming to .218 Bee
Greetings all,
I've already formed a 100 .25/20 WCF to the .218 Bee using one pass through my FL Bee sizing die, then fire forming. They are just a hair shorter than the Bee, but I can live with that.
I just picked up 20 .32/20 WCF brass and wanted to see if this was viable since the brass is so cheap.
Is it too much of a jump to go to the Bee FL or would it be better to try the neck sizing die before full length sizing?
How about reaming the neck die out a bit to .243, 6mm, .25, 6.5mm, or 7mm? And what size do you reamer/s do you suggest?
Where does the extra brass go to? Thicker neck wall, less case capacity...
Thanks in advance for the help guys, Minkman

RapidrobThe length of the Bee case is the problem. Perhaps running the casing into a 7.62x25 die would help at least dropping the caliber from .312
down some.
The neck will have to be thinned.
I doubt you will have to thin the brass since it is so thin to begin with.
However I would expect to use a couple of intermediate dies.
1. The first necking down die might be a 7mm TCU sizer cut off to the right length.
2. The second would be a .25-20 sizer.
The use the Bee sizer.
The necks of the formed cases will need to be annealed for long life.
