OK guys, after making several trips squirrel hunting, I've come to realize these black powder shells have even less knockdown power than I thought they might. I'm using Buffalo Arms 12 ga 1 1/8 oz of 7 1/2 shot with 3 drams of powder. After the hunt this morning, I set up a test comparing these shells vs regular high power shells against a piece of corrugated tin, at about 25 yards. The bp knocked the tin down, but barely dented the tin sheet. When I tried the regular nitro powdered shell, the difference was astounding to say the least. Both these shells were loaded with 7 1/2 shot, but the nitro shot pierced clean through the tin. Now I know this isn't anything new to some here, but I was surprised. Now here's my question. If I start reloading BP shells (2F powder) is there a way to increase the powder load to at least resemble what the nitro powder can do? Would 3F powder come closer to match the nitro powder velocity?
