View Full Version : Lee 40s&w dies for 10mm?
I ran a 10mm case through the resizer and it swallowed the whole case. It looks like there is a slightly wider opening so the case head (primer end) is slightly larger diameter than the rest of the case. On the order of 0.002". I measured this against other factory loaded cartridges and found the wider diameter was the same as the overall factory diameter.
So, am I good to go for reloading 10mm? The reason I ask is that some die sets are listed as 40s&w/ 10mm, and the one I have is only listed as 40s&w.
I have RCBS 10 mm and Lee 40 S&W dies. For me, loading 10 mm with the Lee dies works better. I do run my brass through a 40 cal bulge buster before loading and have never had a problem.
The LEE 40 die will do the 10mm just fine. The RCBS I have from befor the 40S&W was considered will not taper crimp the 40S&W because the die body is too long, got a 40S&W taper crimp for the 40S&W so I'm good to go!
A "Big Thumbs Up" for the use of the "Pass-Thru Die" system to recondition any and all 10mm and 40S&W brass. Just remember a "SMILED" brass cannot be repaired. :headscratch: :sorry: The metal has started to shear on the molecular level! :wow:
I use the old bulge buster for the .40 and 10mm too, but even then I never reload badly bulged brass "hot"
