.40 S&W (yet another caliber)
Here goes nothing. Seems every time I load for a new caliber, it's like discovering another planet. Long story short, I'm loading .40 S&W with Unique (4.7-5.8 gn range) for a 175 gn SWC (#401638 175 gr. #2 Alloy 1.100" OAL). On the contrary, every time I notice the powder fill most of case after first charge I measure the depth from neck to powder and compare it to the boolits I'm using. Considering a 1.1" OAL seems the starting charge is right near the base of boolit. Also my brass is within spec (.845"). My question is, is how does Unique operate under "close confines"?
