AR-15 300 fireball build

Pug,

I didn't like the wide crimp left by my M1 carbine crimp die. But a good crimp was a must for me.
I took my micrometer to Lowes and picked out a verity of 3/8 fender washers. By slipping one around the cartridge before ramming it into the crimp die, I am able to adjust the crimp were I want it. Works for me.

Yep with the Lee factory crimper the sooner you trigger the crimper collet without turning the die down the higher the crimp will be. Sounds like you have got a good method worked out there.
