Yes!Ian there is another option.
copy the Dillon die.
easiest die ever to clean and/or change bullet nose profiles on,,,, ever.
you don't even have to take it out of the press.
it's like they actually thought about cast bullet shooters when they made their seat/crimp dies..
Dillin dies aren’t the cheapest but for ease of cleaning the seaters can’t be beat.
It will be OK Ian, they aren’t blue.
