Loaded some 38 Special yesterday and had 3 cases that wrinkled during bullet seating.
I've been reloading over 30 years and have not seen this before.
Cases are Federal nickel plated. This is the third time they have been reloaded, each time with Hornady 125 XTP's with a maximum powder charge. There are no visible indications of case failure. I have not had to trim due to case stretch.
Sorry, the pictures I took don't show what happened.
All three cartridges are the correct OAL, but the bullets are not seated completely. Instead the case crumpled.
I'm tempted to pull the bullets and toss the brass.
Anyone else had this happen?
