jnsnchzaz Posted June 3, 2015 Share Posted June 3, 2015 I heard a myth that you can trim a .223 case to the length of a 38 super case and it will work in an open sti. Here are my questions. Is it possible? Is it reliable? Is it safe? I am working on purchasing a sti gm in 38 super and I have a ton of 223 brass. if this is a posiblity, it would be nice to save some money on 38 super brass. let me know what you thinks...pros and cons.

DWFAN Posted June 3, 2015 Share Posted June 3, 2015 Wouldnt it be 38 Supercomp or 9x23? 38 super has a bigger rim than .223. Link to comment Share on other sites More sharing options...

tagacali Posted June 5, 2015 Share Posted June 5, 2015 Yes, you can use 223 cases for 38SC. You just have to cut it down, same length for 38sc. Link to comment Share on other sites More sharing options...
Aric Posted June 11, 2015 Share Posted June 11, 2015 Look up .38 super cooper. The .233 case is slightly smaller in diameter than a supercomputer case. It can be done. Link to comment Share on other sites More sharing options...
Guest Posted June 11, 2015 Share Posted June 11, 2015 Possible, but that juice isn't worth the squeeze. Maybe sell some of the .223 brass and use the money towards buying 38 super. Starline has all of the 38 super variants in stock now. Link to comment Share on other sites More sharing options...
Open1215 Posted June 12, 2015 Share Posted June 12, 2015 I saw a neat set up with a case feeder and a auto drive to trim brass. They used it for converting .223 to .22 tcm. They made a video of it and sorta explained the set up. Perhaps if you did that and trimmed a few k in an afternoon then that would be well worth it.

Open1215 Posted June 13, 2015 Share Posted June 13, 2015 Here is one video. I'm not sure if you shoot .300 blk or whisper. Or convert/shoot enough to make it worth it but it seems like it may be a good idea if you would use it enough to purchase the set up. If you had a huge stock pile of 223 brass or had a local range that gave you all the free .223 you wanted you could basically shoot 223/super cooper/ WTF did I pick up, and just leave the brass like the 9mm guys do.

mlmiller1 Posted June 14, 2015 Share Posted June 14, 2015 I dont have a horse in this race but wouldnt it be better to just sell your 223 & buy 38 super or sc? Then you have brand new unfired one single headstamp known history brass? I guess if you have LOTS of time to trim it, it might be ok but I think I would pass on that much trimming.
