"Dump the powder on the roses, and check the cases for Berdan primers."
Milsurp 30-06 that is American made never used berdan primers that I know of. However, hey are definitely corrosive. I the powder smells OK, then it should be good. You can decap those shell with a universal decapping die or you normal sizing ddie. Just ease the decapping pin onto the primer and gently push. A few years back I did that with 600 rounds of WW2 milsurp 06 without any problems. Go slow, be genle and you'll be just fine.
COMPROMISE IS NOT AN OPTION!
