Midsouth are my go-to guys, too... Midsouth won't know anything until Hornady catches up on production - which was why I called Hornady directly. Go directly to the source, and talk to a human. Starline doesn't even have the caliber listed in their rifle brass yet - my plan was to call them tomorrow, and ask directly. I'll put the results up in here tomorrow night.
Talk to humans, brothers, talk to humans. Emails get blown off, but you can corner a human, whilst on the phone, talking to them. Most humans get nervous if they don't know something, or they've been directed not to answer it, and they.... What? ...transfer you to someone higher in the food chain. Or, if they really don't know, then you ASK for a person higher in the food chain. Most of the time, they never had a clue in the first place that they were being interrogated...
Emails, texts, posts on a company's FB page... Meaningless, in the big picture. If they feel like responding, then they will. That doesn't generate near the information - that talking to a human does.
I'm just sayin'...
We've forgotten that, in our cyber-world that we live in.
