Rifling and bullet size in 9mm

[Lloyd Smale]

yup and every factory round of ammo you've ever shot is run through a final size die to insure it runs in even marginal guns. You think maybe its why they call it a "FACTORY" crimp die

Set your 9mm case in the shell holder. Raise the ram full up. Then screw in your Lee CFCD till you feel resistence or gets slightly tight. That's how you adjust amount of crimp. Lock the die down. You can have none to some crimp. Then you adjust the stem for seating depth. I think most of the stigma from the carbide ring crimp die is the die not being set up properly. Most seater dies get run down to flush with the shell holder then the stem adjusted. If you do that with the lee carbide die then you just ruined your round.

This method us using the CFCD like a roll crimp on a seating die. Not at all how the die is intended to be used.

This is the purpose of the CFCD. To be ran down the entire length of the case.

and does factory ammo shoot like **** in your gun because the bullet was swadged down?

I size mine at 356 with problems , many many variables causes problems for everyone

[DocSavage]

Size to .357 as that is the largest I can size without feeding problems. My gripe is that factory barrels are 1 in 10 twist when they should use the 1 in 16 twist of the 38 super. Not a target class shooter myself but I'm under the impression that a 38 super will shoot rings around 9mm Luger.
