I have no idea how old it is but had to try the original stuff ;-).

I'll try some Reloader 7, I've tried H-380 but keep coming back to 3031. The problem with 3031 and none of my powder measures will measure it at the bench so I have to fill a bunch of glass vials at home then take them to the range.

I have not looked at AA No. 9 which I have used in my schuetzen rifles to see if there are .257 Roberts load info to start from.
