“Reloading” — no kidding!
I’ve taken up pizza making as a hobby. There’s simple math involved to calculate the crust ingredients and timing (they even call it “bakers’ math”!). I don’t think he’d make it creating pizzas, but failures wouldn’t be as spectacular as miscalculating loads.
Nice hobby. Not as potentially fatal as a reloading error. Especially with a powder like Hercules 2400.
