.38 special crimp

Post by Kissmybrass » Sat Sep 11, 2021 7:52 pm

Unless I"m not getting this right I cannot crimp .38's with my .38/.357 RCBS die set. Kinda strange this isn't mentioned anywhere. I just reloaded and set the bullets as normal but there is no reach due to the shorter shells. I'm getting a seperate Lee Factory Crimp Die for them unless I hear different.

That’s strange. Did you contact RCBS?

You should be able to. Place a empty case in the shell holder and run the die down until you feel it touch the case. Remove the case and then turn the die down an additional quarter to half a turn. If you have a loaded round back off the seating stem so that it doesn't seat the bullet any further. Run the loaded round again. You should then be able to see a crimp on the loaded round.

KMB, I use a Lee Factory Crimp die. They are bone cheap at around 20 t0 25 bucks, once set good to go and it gives (in my humble opinion) a better crimp.
I use a Hornady progressive or a Redding turret.

I use Hornady or Redding dies, but the Lee is just easier and I get a better crimp.

Don't worry about getting older and still doing stupid stuff. You'll do the stupid stuff as always, only much slower. Hold my beer and watch this.......

The bottom of the die hits the shell holder before any stoppage. Definitely using the right die. Don't know why this is perplexing. I reloaded .357 mags last week with zero problems. I bought the set used so maybe there's a chance this die is .357 only?

Yep, I tested a .357 magnum and it crimped perfectly. The bottom of the die was 1/16" of an inch from the shell holder explaining why .38s won't work.
Top of die reads as is:
RCBS .357 MG SEAT 80

Dies are working out really well minus the .38 crimp. Definitely investing in another Lee Factory crimp

Kmb, for simplicity, get the Lee FCD. I use one for .38/.357 with my old RCBS dies. But, I have in the RCBS box a spacer that is used with the .357 dies, except the sizer. I believe it measures 0.128". Without the spacer, all dies work and crimp .38's with no issue at all. Including the Lee FCD.
Hope this helps a bit.
