Sounds like Pats Reloading. They buy bulk powder and put it up in white plastic 1 gal. containers. Good price's, just keep the stuff straight, and you'll be ok. As far as the ringing in the ears, mine is from high blood pressure. When it's is a normal range, I'm fine. When it goes up, the ringing starts. Just gave blood last week. When the guy checked my pressure, he said it was high. I told him to keep an eye on the bag, and I'll be outta here in no time. gypsyman
