Do NOT use .30-40 brass to make .6mm Lee Navy.

I think there's more than meets the eye. Experienced handloader or not. Mistakes happen and only need be once.

Absolutely Jim, but in this case he followed the recipe in the November American Riflemen article to the tee except for the brass. He bought the brass online from a guy in Texas, so who knows what the story is on the brass. It was the weak link in the chain without a doubt in this case. The rifle let loose on the second shot. Just be aware out there in internet land this was the second rifle to let loose in this manner "that's known about" while using .30-40 brass.
