Sure.

If the case has a semi rim; it falls in your first category.

If "rimless", it's in the latter.

 

maybe it’s my eyes... really hard for me to see this/tell just by looking at it.

 

Lest you forget, there is 9x23mm and 9mm Largo that both share very similar case dimensions.

 

9X23 is a tapered case Z.

The Largo would fall in the “old school” semi rimmed category (from memory)

You know me and "old school". I totally forgot about .38 ACP, the parent of all of the above (except possibly for 9x23mm).

And then there is the 9x23 Steyr as well . . . . .

 

Wow, I guess I never realized there were that many similar cases. I only load for 38 Super +P and 38 Super Comp. I try to only have one of those with me on range day to cut down on time spent sorting.

 

Oh vey....

 

“Rim deduction” be mo easy than “headstamp readin’”.
I’d think it could be done tactile-ly, no sight involved. ( :

 

38 lapua, 9mm Devel, 9mm Super Cooper, etc etc etc

 

In a perfect world, there would be only 38 Super comp.

 

All of the "Super Comp" type cases will load the same. SC, TJ , Lapua and all have the same rim size.
I use a 223. plate on my Dillon and as long as it goes in the plate "I" consider it a SC case and load it. I'm loading most for uspsa open class and loading to major velocity. Shot in a 2011.

Super cases will not fit in the plate so any that got picked up by mistake or just not separated. Get separated during loading.

All of my super cases are old hold overs from years gone by and I use them for fun range practice and occasional steel matches (in 1911's), where we tarp the shooting area so brass is easy to recover. FWIW

 

Lawd......this is giving me a headache.

And to think I was grumbling about having to do sort .45acp for primer pocket size.




Been saving the .38 Super range pick ups with the plan to eventually add a gun in this caliber........looks like more sorting is needed.




I’m going to add a lighted magnifying glass to my brass prep bench. My eyes could use some help.

 

Ok, easiest way I’ve found is to set up my Dillon press in either 38 super or super comp, and just leave the sizing die in.

The comp case wil really wobble and I can just grab it out... if I’m going the other way, the 38 super will not fit into super comp she’ll plate, and Incan just pick it out and toss it into a separate bucket.

Im able to separate and process the cases at the same time. Then, I can run them through my automated 105” as the sizes and deprives cases run smoother in the press.

Saves me a crap ton of eye strain.
