ORIGINAL: eb Yes,I did. With 150 grains of each(pellets) and 240 grn XTP bullets out of a 700 ML Remington,it shot 2246 with 777 and 2218 with the pyrodex.But the 77 was having bad hangfires,so I'm sticking with the pyrodex.
Boy, this is interesting!! WORSE ignition with 777 than Pyrodex?? WOW! Just the opposite of what I would have expected! Guess I'll still stick with loose powder!! (No improvement in ballistics either, I see!!)
