Title: Taper Crimp Die
Post by: Ramjet on March 27 2025 09:57:48 AM MDT
How many of you reloaders for 10mm are using a taper crimp die as a separate operation when reloading cast bullets.

I always crimp in a separate step for pistol. Even on my 550 that only has four stages I have seat and crimp in the last two stations. I visually inspect the powder.

On my 1050 which has more space I am able to also get a powder cop in there, but I still visually inspect with pistol.

Me too for cast, or jacketed, or plated, or coated.   ;)

I always taper crimp for consistency.

I work on a single stage press most of the time.  When seating my bullet in place I use a 1/8" spacer between the die lock ring and the press to raise the die up so the case doesn't make contact with the area that starts to close the case against the bullet while it is moving down into the proper COL.
The use of the spacer allows the die lock ring to remain locked in place as set for the proper crimp setting when the die is screwed down in the press without the spacer.

I have several of these spacers and they serve several operations using different cartridge casings as show below... as you can see from the pictures below.  I can use two 1/8" spacers to work 10mm & 40 S&W between seating / crimping
This picture is the 10mm / 40S&W / 357SIG and 9x25 Dillon cases in relation to each other(https://i.postimg.cc/3NV0NTvS/IMG-0552.jpg) (https://postimg.cc/vx7Z2CXf)

This is the 10mm / 40S&W / 9mm as the sit on the 1/8" spacers
