Brass is buckling

thebluemax · July 15, 2009, 01:07 PM

I did my first batch of reloads in 45 acp no problem everything went smooth. Now I'm working on the second batch of 50 and about every 2nd or 3rd round the case hangs up in the seating die and either the mouth deforms horribly or if the bullet seats theres a valley in the side of the case like the case is bending or other times it with seat with some of the wax from the bullet on the case and slight cut like fingernail or u shaped cut in the wall.

The dies are lee carbide. The cases have been tumpled, resized, decapped, trimmed, mouth flared, charged. What is going on?

Don't know for sure, but I have the same problem. What brand dies are you using? I use Lee. I don't have this problem with any of the other calibers that I load.

How is your expander set? That will cause that.

It sounds like you need to set your expander die a little deeper.

Sounds like you're not expanding the case mouth enough. Could be that you used a different brand or lot of cases in the second batch that might've been a little shorter but did not adjust the expander ball.

Hi,
As others have mentioned, this is an indication of insufficient flare.
set your expander deeper in small (very small) increments until the problem dissapeears.
Cheers,
Danny

I use lee dies. It's always the simple things. I didn't adjust the dies with the second batch.
