A while back, I mentioned using some folded-head (sometimes called balloon-head) .32 S&W Long cases to make .32 Long Colt cases. There were some advantages. They sized down a LOT easier than solid-head cases. so that there was very little filing needed on the outside of the sides, very near the base.
I have formed many of them and shot them since the last post. I have found that there are also disadvantages. I am thinking this is a dead end for getting .32LC cases. One of the problems is after sizing in the tightest resizer (0.314"). Originally, I used a steel rod the size of the inside of the case to drive it out. It often damaged the primer pocket. I drilled a hole in the end of the rod that was just larger than the primer pocket. That way, the rod would rest on the bottom/inside of the case and not touch the primer pocket. Unfortunately, the bottom of the case (the folded portion) would often separate from the rest of the case, leaving the rest of the case stuck in the sizer. Removing the rest of the case was difficult without damaging the sizer. About 15-20% failed. If they did not fail the first forming, they rarely failed after that (but occasionally did).
After shooting some reformed/reloaded cases, I found that the primer pocket enlarged fairly rapidly with use. After about 3 or at most 4 shots, the primer pockets were too loose to hold a primer. I thought about resizing the primer pocket, but decided that this (balloon-head cases) was no longer a quick & easy solution.
But, I have another wild idea. I will put it out here to see if anyone has tried it. I will be looking for some .22 Hornet cases at a gunshow this weekend. It is just a bit smaller in diameter than the .32LC case. I could make a full length inside resizer that would make the .22 Hornet case the same outside diameter as the .32LC case. The sides near the base would not be full diameter. They would "neck-in" near the rim. This should be no different than the 41LC cases I made from .38 Special cases before Starline started making them. It was the easiest case I ever reformed and I never had a case failure at the "neck-in" near the base. I showed it to a number of other people and some of them said I was stupid for shooting the case with the "neck-in". They figured it would eventually explode, but it never did.
