My new pre'64 .32 Special has given my much thought since I got it, and I have been in need of wise counsel a couple of times, but today I broke through.
Originally I had no dies, but I managed to cobble together some 030-30 dies and an expander from a 8mm Mauser. This now seems to work alright for neck sizing the .30-30 cases. They give me enough neck tension as well.
But my first results at the range were poor. Very poor. I started with a black powder jacketed bullet load that I had shot in my .30-30 and quite accurately, 40 grains of 3F black powder and two grains of Universal as a primer to clean up some of the fouling shot into one ragged hole in the .30/30 so I tried that in the .32 Special, thinking it would do alright, since the longer twist rate of the .32 would help out even more.
Nope. Two - three inch groups at 25 metres was the result. I shelved the black powder until I can get a cast bullet mold.
I didn't have the smokeless powder I really would have liked last week, so I tried a smokeless load (from an ADI book) with H4198. This claimed some high velocity for itself in the book, but I was not impressed, I didnt see how it could be going faster than my .44-40, and it turned out it wasn't. No where near it. Anyway the rifle didn't like it at all - six inch groups at 100 metres. I shelved the H4198 powder.
I am still waiting on some factory Federal ammo to show up that I ordered, apparently it is coming by wagon train. So I set to with more reloading as best I could.
So I tried some Varget after finally getting my hands on some. This is the powder I use very successfully in my 1978 Winchester 94 in .30-30, and it shoots very accurately and gives top velocity. I figured if the .32 didn't like slow loads at all, maybe I should try giving it some pressure. I loaded up 37 grain of Varget with the 170 grain Hornady interlock, and shot the below target very carefully.

The first three shots went into one inch, the fourth making it a two inch group at 100 metres. I am very pleased with this indeed. I was thinking of rebarreling or recrowning and all kinds of ridiculousness considering I hadnt even fired any factory ammo in it. But sometimes I get that way....
