Picked up a jar of BLC-2 awhile back just because it was the only powder the store had . Loaded up some test loads but hadn't had a chance to shoot them till today . Like normal the lowest charge was the most accurate with a 150gr spitzer flat bottom bullet . The higher charged test loads started vertical stringing . IMR4320 did almost as good with lower charge also as the BLC-2 . I had heard of people using 4320 but hadn't heard anything on BLC-2 and took more reach to find results .
