	I picked-up some cheap once fired 30-30 Winchester brand brass and tried my hand and forming into 32-40. I first annealed the cases and then lubed with Redding Imperial sizing die wax . Each case went through my Lee full length sizing die fairly easy. There were a couple of dented cases . The reformed cases did come up a little short in length but that was expected. I will be breech seating with a CPA rifle so it should not matter . What does concern me is the bases of the reformed brass is a little larger in diameter at the same area as a real 32-40 WCF case ? Not the rims but about 1/16 " above the rim area . I made sure my sizing die was touching the shell plate and then gave it another 3/4 " of a turn . My CPA rifle is on order so I hope the reformed cases will chamber when I receive my new rifle .

	What you may have to do is put a piece of steel over your shell holder and push the case in all the way till the rim touches the bottom of the die. Now gently as possible tap out the case from the die using a piece of brass rod. This usually only has to be done once. 40 Rod

	Take your calipers and make a mark, all the way around at .200 forward of the back of the rim. Measure the diameter at that point with a mic, if it measures .418 or less. It should chamber w/o any problem. Frank

	I understand 40- Rod what you are saying , however in order to do what you are saying the decapping pin would need to be removed from the die in order to take a piece of brass rod and punch out the shell from the die .There are two problems that I see , first the decapping pin is not a straight piece of steel it is tapered and is wider or a has a bulge to support the long 32-40 case and removing that would have the case collapse in on itself ? Second punching out the case from the top of the die might punch through the pocket primer hole ? If you could point me in the right direction , or if I'am missing something please let me know . Thanks

	My RCBS 32-40 cowboy die has a large enough hole that with the decapping stem out you could fit an wood or aluminum rod from the top to tap on. Jack

	What 40rod and Jack says. I remove the de-capping pin rod. Push the shell all the way in , tap it out with a brass drift. My de-capping pin rods are not tapered so no support on the inside of the neck. The cases will not collapse. I've down hundreds and hundresds and never had a problem. Dies are RCBS cowboy. Joe.

	Quote: Not the rims but about 1/16 " above the rim area . This area of the case DOES NOT come in contact with the chamber and as long is it isn't larger than .320, don't worry about it. That area of the case is solid brass and can't be re-sized. The first .200 of almost all cases is solid brass. It has to be to receive the primer pocket. Large rifle primers are about 1/8 long and they have to have brass in front of them to keep them from braking through. The position that I discribed in my first post, is on a taper in the chamber and gets larger as it proceeds to the rear. Frank

	Have never had to size 30-30 brass all the way to the rim to fit a 32-40 chamber. Have had to with .32 MS and some others. The head can be sized. Push harder. I have a jig I use a hydraulic jack with. Joe.
