Okay so there is a tool for this which tells me it is not uncommon. But was this just a strange phenomenon that just happened to brass that had been loaded with h1000 and none of my other have had the issue.
Darker I don't have a chrony yet. The data is for a 24" barrel I have a 22" barrel. I don't exceed the max and rarely go to the max, because I am just not comfortable in my going on 2 years loading ammo. I start low and work up till I find a nice node then play with seating depth. Scope Eye I like your idea! I just threw the cases away though. I got plenty of others. I am getting a chrony for Fathers day which is really cool. I think it will help a lot with interpreting the nods. Thanks for the input guys.
