Rum River, I moved out to 100 today, tried different powder and soft and hard balls out of my new .73 cal.........up till today, fifty has been my farthest shot.
My first group was 3 1/2" using a hard .715 ball and 100 FFF, 1200fps.
Then I tried several other combinatios 100 and 150FF and 125FFF......BIGGER groups!
Then I got out the soft lead, 150FF, 7" string, then back to 100FFF and I shot a 1 5/16" group. With the .720 diameter balls, it was almost a cloverleaf! I used a wad under the same load and it was 2"s high.
Most of the time this gun has shot better with a card wad under the ball, but not so today!
