I was loading up five 30 Luger cartridges for tests in my 7.65 Parabellum-chambered Star BM and took out some brand new Winchester 30 Luger unprimed shells to set my RCBS dies up.
After setting the dies up, I started to run my shortened & sized 5.56mm Remington/NATO cases through the seating die and I was running into OAL case length issues... It turns out the new unused Winchester shell cases are too short for 7.65 Parabellum specs...They run .840" and the accepted tolerance is .845" - .850" OAL... The Winchester cases have .005" to .010" less neck. That means they don't grip the bullet as well as a full-length case. I'm setting my case trimmer to .850" to get as much neck as possible. Just a heads-up, if your die doesn't seem to be taper crimping the Winchester case neck down tight enough to hold the bullet securely...
