Lyman M die
 

Got my new lyman m die. Looks just like a expander or flair die I have from RCBS. I was hoping for a little difference.

Since it is designed to perform the exact same task, what kind of a difference were you hoping for??

Hey, it comes in an orange box, now there's a difference.[8D]

Ok, are these trick questions? Elde, you crack me up


They advertise that it will make a 2 step expansion for easier loadings of lead. The first ring that does the first expansion isn't much, the second one that does the main expansion looks just like a RCBS expander/flair die.

so you got this for your 45-70?? Im guessing?? is this die to aleviate scraping the bullet with the case? help me out havent heard of em. can you use them with bottleneck cartridges, or would neck tension suffer?

I only use them on bottle neck cartridges. It sort of steps out the front edge of the case mouth a few thou, keeps it from shaving lead off the bullet, I use them for flat based jacketed bullets too. I haven't used them for pistol cartridges as the standard case mouth belling die does an adequate job by itself. A good way to use them if you are FL resizing, is to use a universal decapping die, then remove the expander ball from the resizing die and use an M die to reexpand the neck- you eliminate the possibility of uneven neck stretching that you can get from pulling an expander ball out of the neck.
