38-55 to 32-40 (Read 5929 times)

	I know I have read about this case forming, but searching today did not result in threads.n I have a CPA 32-40coming and am preparing for it's arrival. I am making 32-40 cases out of 35-55 new brass, I first anneal the cases, then lightly lube with Imperial Sizing Wax. Using a FL 32-40 reloading die, I form the cases. BUT I am ending up with a 10% lose due to very short but deep folds in the cases anywhere from 1/4" to 3/4" down the case body. Is there a better method?

	Very lightly lube the annealed case with Imperial wax, run it up into your sizing die until you feel firm resistance. Withdraw the case and re-distribute the sizing lube with your fingers. Examine the case for any surface dents or wrinkles starting. Those imperfections indicate you are being too aggressive in sizing. Run up into the sizing die until you feel firm resistance . . . Repeat this process until the case is fully sized. It usually takes 3-5 reps of the process to fully size a case without damaging it. Using this process, I have reformed more than 200 38-55 cases to 32-40 (Starline brass) loosing about 4 out of a 100 to the wrinkles & folds like you stated. Keep in mind that too much case lube is as destructive to your brass as is too little. Best of luck

	I had the same problem. I spoke with the folks at Redding and they suggested I perform with 32 Win. Special full length die, then FL with the 32-40 FL die. I did not loose a single case after that. I also did the same reforming 30-30 to 32 40 with out loosing a case. I was lucky as I had a 32 Win Special die set. ron

	I have used the same gradual reforming process, and using Hornady or Midway spray lube. It's very good at lubricating without over lubricating. If I run the dies down in 3-4 hits, I never lose a case. I've also had great luck resizing .32 Win. Spl. cases for my .32-40's. Since I don't own a .32 Win. Spl. anymore, and don't plan to, I've resized all those cases to .32-40 and no lost cases. I can do them in 1-2 shots through the dies with the spray lube.

	I too encountered folds--In my case i avoided the problem which i felt was caused by minor almost undetectable dents or irregularities (old but unused Win 38-55 brass) at the case mouth edge by inserting a bottle necked brass case neck first to at least straighten if not very, very slightly flare the rim edge.

The sizing wax is creating a hydralic pressure that causes the brass to fold in ... Use Bag Balm (a finger wipe) and lower the die ram slowly. Maybe one or 2 buckles over the years (You need to *Login* or *Register* to view media files and links)

	I use 32-40 FLS dies on 30-30 brass. No problems, but might could be a whisker short.

	Travelor, Back off your dies. If you have set to the Shell holder and you are depending on your sense of feel you will not be consistent on how far you drive them into the Die. Back off the Die until you can just feel it starting to Size the brass down. Once you have started a fold, following sizing will just continue the process. Clean and thin out the case lube for following efforts and do it in small increments of re adjusting the Die deeper. The other way also would be to hit a Gun Show and look for .32 special Dies as suggested by another Poster here. HTH, Regards, FITZ.

	What Fitz says. Also, I just size them down to the place they chamber- not necessarily all the way to the damn shell holder. No need to mash 'em more than needed. Even once fired in a sloppy chambered lever gun will usually be smaller at the base than the typical chamber. Your CPA chamber might be snug on once fired brass, by my original Winchester sure ain't.

	What Fitz said. Remember don't slap it on like your greasing a ball joint. With Imperial a little goes a long way. I bought a can 20 years ago and have resized a couple of thousand cases, I don't think I’ll live long enough to use up the can. I don’t know how Joe made money on this stuff as long as a can lasts. 40 Rod

Try a dozen where you anneal, partially FLS, anneal again, and finish FLS. Sense the amount of force it takes. That may give you an indication of just what point of sizing the collapse/wrinkles occur. Sizing 14ga down to 577-450 is a similar game.

	Similar to Emmett, I suspect small dents in the mouths of the cases as the cause of some of the folding. My approach, though, is to run the cases into a 38-55 expander die short of belling the mouths. Then I use Imperial Sizing Wax applied SPARINGLY. I'll lube a bunch of cases I'm going to reform and run them all in turn into the 32-40 die set to reform them about 1/4 way, then redistribute the wax on them, run them all in again with the die set a bit farther down, etc., until I've reformed them in about 4 passes. Done carefully I lose 2 or 3 cases per hundred.
