Yes, the pellets are even worse. At least they can say it cost a lot to make the pellets. No idea if that's true, or not.
BH shouldn't cost anymore than any other smokeless to make. I've never seen any smokeless powder that only comes with only 10oz.
One advantage I have by shooting close is I don't need heavy loads of BH. So, I save some money. 80gr is plenty for my distances. I know 100gr loads is 62 loads from a bottle. I'm doing better than that. You must be using 110-120?
