Way back when I bought up a bunch of Black Mag 3 because it was clean and at the time was the hottest ticket. Then came Blackhorn 209. I am now about to shoot my first round of Blackhorn. It has been years since anyone has compared the two so I need a little refresher on the different. Do I use about the same amount of 209 as I used in Black Mag 3? Refresh my memory please.
