Years ago a friends wife went from her trusty lever gun to an A bolt.
She was concerned about the difference in operation and the cost/recoil in getting used to the new gun so I offered to run up some cast loads for the purpose.
Push come to shove I got part of a box of loaded rounds back.
I needed entertainment the other day while letting a gun I was testing loads for cool down between groups so I drug out the trusty 03 BOOLIT gun. Entertainment, empty the brass, and get some extra shooting time in worked for me. Well the load I put up all those years ago shot very well so when I got home I broke on down, unknown primer (likely WLR), 150 RCBS FPGC, 16 grains of powder.
WHAT HE HECK POWDER IS THAT??????
I do not recognize it as any powder I have, not a spherical, flake or rod shape. Small particles in physical size.
Why didn't I label that box of rounds, I would like to duplicate the load because it shot very well.
I have poured powder out of every container I have and none are even close. I have run out of only one powder but can not imagine using it and certainly not at 16 grains.
Gist of the story . . . .
Label, Label, Label the load information.
