I have always seated pistol bullets in one die and crimped them in another die: two separate functions. I have bought separate crimp dies to allow this and current die sets have one die that does both. This leads to my question.
In my old age, I like to have one of those RCBS powder check dies on my turret press or other progressive press. This of course takes up a die station and it can work but I am confronted with the prospect of seating / crimping at one die station. Now I got the dies so thats not the issue here , what I am concerned about is how much degradation of accuracy can I expect when I use one die for this purpose for cast bullets.
I am especially concerned with the 9mm as its so fickle with its already tapered case which if improperly expanded will shave lead off bullets. I am concerned that seating while crimping will foul up the bullets and all I achieve is loss of accuracy.
So the question is , with your patience please: Do you use one die for seat and crimp of cast bullet reloads and is there a down side to that practice as I fear there is.
I thank you for your time and experience
