You're not supposed to have lead flavored pies? :-)I wonder if anyone notices the extra lead flavor in your wife's pies?
I always take a 2.5 gallon bucket with a screw on lid to the range, with those pie plates to hold fresh ammo and some of the cheap round Tupperware plastic tubs for the spent cases. They all stack neatly in the bucket, and help with me keeping the brass sorted in the field.
