Lee Load master

[aviator41]

In the picture below, the left two have a crimp made by a Lee Factory Crimp Die. The rightmost is crimped using the Lee bullet seater with the roll crimp built in.

Left is 30-06 with light FCD crimp, middle 30-30 with heavy FCD crimp, right 45Colt with heavy roll crimp.

I understand that you're only supposed to crimp if the bullet has serrations.

Or is it to each his own?

Serrations are called the cannelure. You can crimp outside of the cannelure without problems as the OAL of the round is more important than the crimp location. in fact, many of my rounds crimp outside of it - many don't have one at all and get crimped. (none of the rounds in the pic have a cannelure).

OAL trumps cannelure location every time.

here are some examples of cannelure variation on 5.56 rounds loaded at the same time, one the same press.

Yea I forgot what they were called.
Looks like I need a 9mm crimper

If it has lee dies on it, the bullet seater has the crimp built in. please re-read my post or post the type of dies on the press.

I will check when I get home. I'm 99.99% sure it's all lee dies.
