.223 Brass Choices

[MarshallDodge]

Y'all must be running it hotter than I do, or did. I need to look up my test and see what I was running, or maybe my Federal cases happened to be a good batch.

Similar here. Like me, you're probably not running hot loads and set your dies up to keep from overworking the brass. It could also be the difference of firing in an AR or bolt action.
