John,

I had seen that, too. I haven't tried it, although I did make .257 Wby brass out of 7mm Rem Mag Winchester brass. Cases were just a tad short, but they worked OK.

With the .240's I was a bit concerned about the belt and if sizing the case that much may create a weakness where the case body meets the base/belt. If your newly formed cases looked perfect, where do you think the problem was?
