I agree, what kind of press and powder?
Myself, I just got a Hornady Lock and Load AP progressive this week. I also got the RCBS lock-out die that will prevent the press from cycling if there is an undercharge or doublecharge. It's not a substitute for a visual check, which I have done every turn, but it's a good human error preventer.
And yes, I tested it with an empty case, and with a double charge case. It works great!

America is at an awkward stage. It's too late to work within the system, but too early to shoot the bastards.
