DWalt, my experience mirrors yours. I too have shot many .32 ACP rounds through some of my S&W .32 Long chambered revolvers, in fact some of the ones shown in my post above, and not only do they not split, but because they are semi-rimmed, the ejector will pick them up and eject them. One caveat, though, the rim is very shallow, and best results are obtained by holding the revolver vertical and smartly tapping the ejector rod to avoid a spent cartridge slipping under the ejector star.

Best Regards, Les
