I've recenty been on a thread discussing the .32 S&W Long as a man-stopper. As part of the discussion, I worked up a very nice load in the 32 long that geatured a hard LSW over 8.0g H110 powder. It had considerably more snap than factory rounds, but didn't flatten primers or stick cases: They would often fall out when I raised the muzzle. Then I discovered that the crane on my little M30 32 Long was bent to the point that the gun didn't want to close.
I put it away until I could look it over closely and see what was binding. Fortunately, the crane was easily bent back into alignment, but I decided that the aforementined loads woud be reserved for more heavily constructed revolvers.
Having several boxes of 32 Long loaded with 8.0g H110 and a hefty swc, I undertook to recover the cases by firing them in my Ruger 32 Mag. This worked very well, and the cases droped out with no primer flattening of bulged cases. Thus emboldened, I tried them in my 32 long H&R revolver. I got the same results, and there was every evidence of moderate loads, and none of seriously excessive pressures.
This load seems quite moderate in the .32 Mag and the H&R 32 Long, but seems to be far too hot for the S&W. What could be causing pressures in the M30 to be so high that they bent the crane? What am I doing wrong?
