Reloading 9mm that was used for major/open

[oneskilledshooter]

I needed brass for 9mm so I got a bunch of range brass. Some of it was used for major and will be bulged and will therefore not chamber in my 9mm after I reload it in my dillon square deal.

Questions:

1. Is there a fast/easy way to tell if it was used in major and will have the bulge?
2. Is there a way I can full length resize it for use in 9mm? I do have a single stage press and a 3 die carbide RCBS set but I haven't used them before.

I know I can load them all, then chamber check and pull the bulged ones but I may have a fair percentage that either have the glock or major load bulge.

A lee factory crimp die will get rid of a bulge no problem BUT I would be careful about using that brass personally. A bulged 9mm major case means that the gun unlocked before the pressure in the chamber was all gone or they just have a loose chamber. Either way, I like my guns and personally wouldn't use it because it could easily cause a case rupture.

9mm major from a tight chamber with a long lock up, good to go though.

The only way I would use 9 major brass was if it was roll sized.

So how does a factory crimp die fit in to my current process with my dillon? I guess I would have to deprime, then the lee factory crimp die, then on to the dillon?

What specific die would you suggest? I have an RCBS 20515 3 die set and the sizer just says FL on it, but I guess it doesn't really full length size. From what I understand it is sizing not quite all the way down in the same way that my dillon die does.

The Lee crimp post size die is the very last step or station. After the bullet is seated, the post crimp/sizing die re-sizes the case and takes out any buldge or imperfection.

cool, thanks! Looks like this is what I need - http://leeprecision.com/carbide-factory-crimp-die-9mm.html

"...fast/easy way to tell if..." There's no way of telling anything about 'range brass'. That's one reason not to use it.
"...full length resize..." Handgun dies do that anyway. There's no such thing as neck sizing handgun brass(except for the few bottle shaped cases there are. IE .357 Sig). That's a bottle neck case thing only.

Roll sizing is not performed with a conventional die.
It is a machine unto itself.
Do a search for Scharch or casepro.

After you have finished reloading on your SDB, run them through the factory crimp die on your single stage press.

I had to do this with a batch of commercially reloaded 9mm that wouldn't chamber in one gun with a tight chamber. After, they all chambered perfectly.
