digerup Posted September 15, 2010 Share Posted September 15, 2010 I just purchased a 38 super and was going to load some rounds, my rcbs dies are for 38 super or 9mm. I ordered a set of dillon dies specifically for 38 super but they havent arrived yet. Is there enought difference between the dies to make a difference, I understand that 9mm is a tapered case and 38 super is a straight wall, so are rcbs dies tapered or straight?

NickAument Posted September 15, 2010 Share Posted September 15, 2010 when it comes to 9 and 38 Super I've never heard of one size die fits all!? shellplates YES, dies ???? Link to comment Share on other sites More sharing options...
warpspeed Posted September 15, 2010 Share Posted September 15, 2010 How are they marked ? They should be marked on the outside what caliber they are for. 9mm and 38 super are not interchangeable. There is enough difference. Link to comment Share on other sites More sharing options...
NickAument Posted September 15, 2010 Share Posted September 15, 2010 I just checked an old set I had and they are marked 9x19, 9x21, and 9x23 * NOoooo Super anywhere on the box? * which makes sense as the only diff in these are the OAL of the case.

GrumpyOne Posted September 15, 2010 Share Posted September 15, 2010 You could probably seat and crimp with those dies, but not size. Link to comment Share on other sites More sharing options...
gng4life Posted September 15, 2010 Share Posted September 15, 2010 The Dillon die numbers are listed here: 9mm - 14406 38Super - 14399 Even thought the base diameter is the same, the dies are different enough to need a different set for each caliber.

gunther Posted September 22, 2010 Share Posted September 22, 2010 I have always used 38 super dies to load 9mm with no problems. I think they feed better. The 38 super dies size down to .384 at the base as the 9mm die sizes down to .391 at the base. It takes care of that bulged casing very nicely. But hey, don't listen to me.

G-ManBart Posted September 22, 2010 Share Posted September 22, 2010 Even thought the base diameter is the same, the dies are different enough to need a different set for each caliber. 9x19 is .391" just above the extractor groove and Super is .384"....not a massive difference, but certainly not the same.

bassochist Posted September 22, 2010 Share Posted September 22, 2010 (edited) the dies are not the same, but, i know a few shooters who reload .38super with an 9mm die set, and it works fine for them, no malfunction or what so ever, a few weeks ago i started to work on some 9mm loads, and by accident i made the first batch of 100 with my .38super dies, i have shot them but no problem at all.

photoracer Posted September 27, 2010 Share Posted September 27, 2010 I experimented with both a set of 9mm dies and a set of 38 Super dies for loading 9x23mm (I changed one die at a time to see the effects). The one thing I did notice is that a 38 Super gun seems to be able to chamber and fire a 9x23 but a 9x23 will not chamber and fire a 38 Super regardless of whether it was reloaded on a 38 Super or 9mm die set. Of course a custom chamber cut could make it work. The only rounds off my press that don't chamber in my 9x23 gun are either 38 Super reloads of any type and some early Starline 9 Super Comp that accidentally got size when I was experimenting with the 38 Super dies. Current Starline 9x23 brass is labeled "9x23 Comp" and it has a new internal taper to allow the use of 147g bullets. So to answer the question reload 9x19-9x23 with a set of 9mm dies only it is better to leave 38 Super for 38 Super dies. RCBS lists a set of dies that cover all those calibers and one of my local gunshops has a set but I'm not inclined to buy them and see if they really do.
