I had the best groups with

1 . Traditions Pursuit pro 28'' barrel - 100 grains of Pyrodex

2 , Encore 26'' barrel- 90 grains pf Pyrodex

3 . Encore 26 ''barrel 90 grains - BH209

4. Encore 26'' barrel - 85 grains of 777

But i use a 300 grain xtp. . The last time i shot my encore 26 '' barrel and used 100 grains of Pyrodex i could see black powder on the snow 3-10 feet in front of me , so i lowered the charge and then there was very little . I wounder how much powder goes out the barrel un burned with Mag Loads . ????
