I just bought a bunch of shot, lead and various casting items that came from an estate of an old reloader and caster.
Included was also a bunch of powder. The red dot , Unique and H335 I have no problem with. What was opened all seems fine and I plan on using.
However there are multiple unopened 8# boxes of Magnum Rifle MR-3100 from the: Sonday Powder Co., Lake Villa, Illinois. It was stored with the other powder so I am assuming its fine but have no idea what to use it for.
There's also several boxes of Hodgdon H870 which at least I recognize the brand but have no idea what to use it for either.
These mostly 8# of powder in a black plastic bag inside a cardboard box I'm guessing from the 60's or 70's.
Can anyone help me? what do I have and are they more then fertilizer?
