I like to select the powder load such that a double charge will overfill the case.
Double charge? I do a load development and determine the exact amount of powder that works the best as far as MV and accuracy.
used a paperclip, with a bent end to feel the bottom of the case perimeter; to reject worn cases
Interesting, do you know what he's feeling for?
I thought you only loaded 6.5mm for the big guy. A .243 is big enough to be effective, good choice.
I've got 6.5 yes, and also larger calibres like .308 and greater. I don't say or show them all here, one never knows who's watching.
I'd like to do some casting but am not currently set up for it. A good skill I think.
Double charge is stupid, but if it overflows the problem is obvious. I do this, as he recommended; as an extra precaution.
He's feeling for the beginnings of a crack forming around the base of the case where the primer goes. It is especially apparent on high powered reloads like the 300 win mag, where the base skirt transitions to the normal case siding.
Casting can give you extra capabilities! They also have a metallized clay that can be sintered after forming!
