.32 Rem
I bought 3 boxes of Remington 32 Rem loaded ammo from a guy 2 weeks before Christmas in 2014. Then 3 months later I bought a Rem Model 14 in .32 Rem from the same man. He had 2 Rem Model 14 's, one in 32 Rem, and the other in 35 Rem. If I had done my homework, , I would have bought the .35 Rem as ammo and bullets are still available. Also modern reloading recipes.
Fast forward a year later to this spring. I am an ammo collector and go to Collectible Cartridge Shows in St. Louis Mo. and Sioux Falls South Dakota. In St. Louis I found 2 more boxes of .32 Rem , 1 factory and 1 reloads $20 each. At the same show I found 3 boxes of New Un-Primed Empties which cost me $10 per box. You would think at a Cartridge Show that the prices would be higher. But you are not dealing with online sellers, where they steadily increase prices for obsolete ammo, and increase them higher than the last guy.
So that gave me 8 boxes of brass. The reloads were pulled, and when reloaded and fired, I lost 8 to cracked necks. When I was visiting my old neighbor in Wisconsin, he said that he had 2 boxes of once fired .32 Rem that he shot in the early 70's. So that added 2 more boxes.
You would think that my problems were over----NOT. Try and find bullets that can be used in the .32 Rem. The Hornady 170 grain flat tip and 170 grain flex tip have the cannelure too far back from the bullet tip. They were made for the Win .32 Special. The Model 14 has a critical overall cartridge length, so it can be inserted into the spiral tube magazine and feed into the chamber. The Hornady bullets can be used if one buys a canneluring tool for about $125. The Speer bullets have the cannelure closer to the tip, and can be used . Also the cartridge case has to be trimmed to the minimum of 2.030 inches so the bullet can be crimped. Midway USA delivered 2 boxes of Speer 170 grainers last Friday. If you have a Rem model 30 bolt action, the crimping is not necessary, and your problems are solved.
I bought a sample pack 2 months ago of 170 grain Hi-Tec coated bullets from MBC that were made for the 32-40 Rifle. The bullet diameter is the same .321 inches. I loaded some up with 3 different powders ( IMR3031--IMR 4198--- and Win 748) at the minimum charge loadings. They all created a puff of smoke when shot. They would not stay on a 8X11 sheet of target paper at 50 yards, because they were pushed too fast ( about 1800 fps ).
I had a post on this site last week asking about different powders to use with lead bullets, and Trail Boss was suggested. So I was on a quest for Trail Boss. My son-in-law found 2 cans in Greenville SC. last weekend, so that is solved. I also went on ebay and got a Lyman reloading manual number 45, and it had loadings for obsolete calibers. Evidently the .32 Rem was obsolete in 1970. They listed Unique loadings for 164 grain lead bullets. I will try the Trail boss first hopefully this week at the range. The MBC bullets are $55 per 500. The Speer bullets were $30.49 per 100. Do the math. The MBC bullets are cheaper, but I have to load them to a slower velocity to make them work.
All I can say is GOOD LUCK.
