Selling it was my wife's idea. She said that if I die with any unused powder in the magazine, she will use it in her flower beds.
There is more powder there than I can use in the rest of my life, no matter how long I live or how much I shoot. My son pointed out that some guys might be desperate for powder and it would by wrong for me to sit on a hoard that I don't need.
Don't start pming me about other powders. Other than WW571, there is nothing else there I am willing to sell. WW571 is the same powder as HS7. I used to use if fro 12 ga slugs and heavy bullets in 357, 44 Mag and 45 Colt.
