    Will the 9 mm Luger shell plate (Dillon 550) work with the .38 SC, or will I need to use a .223 shell plate??

    Thanks.

    I use the 9MM plate on my LNL, but I can't speak for the Dillon.

    Supercomp requires the #3, 223/380 Shellplate and Locator Buttons.

    I just tried .38 Supercomp brass in my .223/.380 plate and it works with it as well. LNL of course. Interesting.

    The .38 Super Comp is a .38 Super without the stupid rim (unlike 9x23, that is a lengthened 9x19 with the same size head). It fits best in the .223 shell plate. Since the .38 Super, with the stupid rim, doesn't fit the 9x19 shell plate very well, the smaller head of the .38 SC will be an even poorer fit. It "might" work, until the press rips a case out of the too large shell plate...

    Thanks for the insight. I bought a couple thousand Supercomp pieces of starline brass for my supers because I expected problems with the rim but they never were an issue. I figured I need to get the supercomp brass used up so I was going to start loading in soon. I was about to ask a similar question for my Pro2000.

    38 super comp was designed to work in double-stack autos, usually STI's or other customs. My single stack 38 super runs the semi-rimmed or the super comp shells both just fine.

    I reload 38 Super with mixed brass on my 550 with the 9mm shell plate without issue. About half my brass is super comp, the other half standard 39 Super, with some Todd Jarret thrown in for good measure. I have never had an issue with ripped up rims... and most of my brass has been though the press 5 or 6 times.

    I shoot .38 Super in my double stacks and never had an issue. I could see the benefit of eliminating a "possible" problem, but it simply has never happened.
    Starline was kind enough to send me 12 SC cases. I've run them through my .38 Supers and they work fine--no "tuning" of extractors needed or anything. Mixed with .38 Supers, they group the same even in a mixed magazine.

    Buy the 223 shell plate you can't go wrong..I load both and the tj brass will just push out when seating new primer..so I stopped all question I also load on a 650 Mach.

    I haven't tried loading them yet, but I've read on another forum that they'll work with the 9mm plate. When using the 223 plate, only SuperComp (maybe TJ too) will fit so you can prevent regular Super or 9x23Win cases from entering your process. SuperComp (TJ?) will allow for an extra round to fit in some double stack magazines that rimmed Super or 9mm does not. In my pistol, semi-rimmed Super needs more slide velocity to function properly (probably due to the semi-rim sitting in the extractor groove of the round below it).
