Well I tried to install 5 in some 30/06 cases last night, went in tighter then well you know the rest, some have marks on them from applying force to seat them round mark , from my RCBS hand primer old one from back in early 2000, strip type.
So you think they will go boom, or not?
Maybe anvil got messed up.
Maybe need a primer pocket reamer which will make the Winchester primers too easy to install, next time.
Cases are unfired resized Winchester cases.
Thanks
Jeff
