Many years of loading and many many kinds and sizes of powder.
I was transferring from a 8lb jug to my 1 lb jug of HP 38 )actually used a funnel as always and didn't spill a grain)
Shook it up and filled the powder hopper and proceed to check my drop weigh. Hmmm, I say what's going on? Why so heavy? I check again again, Get a different scale. Wat's going on?
Then I check the large jug, on know it's H335!!
Damn it!
I keep my rifle and handgun powder separated but put this jug in the wrong place and know I looked at the label twice. So it was a expensive pound of fertilizer!!
I am very anal and OCD so it can happen to anyone.
Only problem was my Wife was not home so I could not blame her.
Be careful out there!
