all of my brass in the last batch of .270 win that had been shot with the H1000 had the primers fall out of them over time. 24 pieces sat for approx 8 months? They had been from a load work up, which by the way produced bad groupings and I am no longer trying h1000 with .270win. My assumption is the pockets were stretched during firing, but there were no other signs of a hot load at least that I caught. No tough extractions the brass appeared to be in good shape. I have not changed primers. I do ream the primer pockets during prep, but just with a hand reamer. all the primers were in the box so yes I did prime them!!! I have only had two other primers fall out that I can remember.


I had mentioned this as a side note in another post but I have gotten curious since and figured this would be seen by more since it is a separate topic.
