I had few hundred 32 Auto cases to load. They have been sized and primed and sitting on my desk for months. So I finally switched the tool head in the Dillon and did the deed.
I had 500 of the CamPro 85gr plated bullets and 50 of the Lehigh Defense 55gr copper bullets.
The light 55 gr bullets needed a faster powder than the 85 gr bullets, so I did my research and decided to load 3.1 gr of Win 231 (fast) for the 55 gr copper bullets and 3.1 gr of Power Pistol (slow) for the 85 gr plated bullets.
The 55 gr bullets were loaded. They chronographed at 1145fps out of a Colt 1903. Perfect.
I then loaded the 85 gr bullets, but forgot to change powders. The book says that 2.4 is the max load for 231. I loaded 3.1
I discovered my mistake as I was making the label for the box of several hundreds rounds I had just loaded. I reached for my inertia hammer, and found it would not work.
I did not want to toss 300 cases and bullets. What to do?
Then I recalled that the 32 Auto is semi-rimmed and will chamber in a 32 revolver. I have several quality (strong) revolvers, so maybe this hot ammo would work in the revolver. I tested 3 rounds. 875fps (about right for a 32 revolver) and the empties dropped right out. No pressure at all. I guess the long chamber in front of the short 32Auto case acted as a very long leade and dropped the pressure.
So I labeled the box of 32 Auto as “Revolver Only”. Probably a lifetime supply of ammo.
I was curious about how hot the same ammo would be in a 32ACP pistol, so I fired one round through a disposable pistol – 1030 fps. Max would be around 900 with the correct powder. Pistol was not damaged, but the empty went into low earth orbit.
The loading error was caused by the 3.1 gr being common to both loads. Because I did not have to change the weight, I overlooked changing the powder.
