I have a large amount of 38 SP brass that I had sized earlier last year without reloading them. There was other brass I did reload. This week I went to the range and found the batch of ammo I brought would not chamber in my S&W snub nose 38. When I got home I found that the same rounds chambered fine in two other revolvers, and was a bit tight in one of my LCR's.
I then looked at samples from the other 38 loads I had made up and some did not chamber in the snub nose and some did. Again, the ones that did not fit in that 38 did fit in my other revolvers. Based on the samples it looks like all the unloaded but sized brass does fit in the chamber just fine.
I surmise that the chambers on this particular snub nose are a bit tighter than normal, but I am not sure how I ended up with such a disparity between different cases I sized. There are the differences arising from different manufacturers but there is more to it than that because I have some that fits and some that doesn't from the same maker. Is this the result of setting up the sizing die incorrectly? Would you guess that I didn't have the die adjusted down far enough for one of the batches?
