you need to anneal the brass just part way I like to use a deep well socket

then drop in water
I like to this spay case lube ( I have used it for swaging jacketed bullets )

back the die up until it's still lock in but high enough so just grabs the case

then tease it in and out till it looks like this

teasing the case in and of the die ,turn the die down 1/2 a turn at a time until you get to the you get to the anneal spot on the case

trim case & then re anneal

re lube case and repeat teasing the case in and of the die ,turn the die down 1/2 a turn at a time until you bottom the die out

I would prefer to use a from die and I have a friend drilling me out a lee sizing die
thanks to dougstump of gun boards for the idea drilling the size die out http://forums.gunboards.com/showthread.php?t=71773
but if you get in a hurry to make some , hope this helps
