Here's my report from this morning with double ball in the .50 caliber. Set the first target at 20 yards cause it's my average deer shot. At that distance it would put a bad hurt on one. Tried 80grs. of 2f Goex first...then 90grs. for the second shot. Moved back to 40yds. and wasn't impressed. They start flying wild out there. I think in the morning I'll use a felt wad between powder/ball and ball to see what happens.
