Dave. I would imagine that outfit would have liability insurance. Then again, maybe not. It was the cost of liability insurance that put me out of business. I'd ask. Sorry to be so simplistic
If ir were me, I'd ask him what he put in those loads. Then buy a box and break ten rounds picked at random and weigh them. If he says, for example 7.5 gr. of Unique, the total weight of the ten rounds should be in the 75 gr. average ballpark. Remember, if the total has a tenths figure, like say 75.6, then the average charge would be 7.56 gr. Sorry to be so simplistic, but I wanted to be sure you understood where I was coming from.
