I'll try and get a picture uploaded, but I'm getting a lip on the bottom of my gas checks after seating them onto my Mihec 65gr NATO boolits. This occurs with my Lee .225" and my NOE .225" push through dies. The issue is worse with aluminum checks, but also occurs on copper checks. I believe the issue is the pushrod diameter being too small, at .220". Seems like the check material is forming into that .005" void between sizer die and pushrod. Any other ideas? I've tried sizing first and then running them through again to install the check, I've tried lube, powder coating first, making sure the check is fully seated before running them through. For now I'm stuck sizing base first.
