I've started reloading some of my left over piled up 40cal. rounds and am crushing some of the shells on about every 5th round. Any body have any ideas?
Using Lee classic press
RCBS 3-die carb. 40/10 dies
winchester new brass
180g hornady xtp bullets
my oal is 1.135" per the nosler reloading book
Like I said it only happens every 5th round or so, plus my die is leaving a ring around the bullet just under the cuts on the hollow point for the petals. If that is a big deal or a sign of something.
I was wondering if I just didn't chamfer enough on those few rounds that are crushing? Here are some pics:
