tried some .50 maxi balls I purchased from a guy in Iowa off Auction Arms yesterday and they shot real well out of my TC Greyhawk. I like the bullets only thing is I don't know how heavy they are, tried to weigh them but my scale tops out at 400gr. Has anyone else bought any of these? how they work for you? do you know how much they weigh? The guy always has lots of bullets for sale so someone else must be shooting them.
