Took the ol 54 mountain stalker out just to mess around with. I wanted to try 80gr 3f JSG .018 pillow tick patch and the .530 round ball. Did okay at 50 yards for three shots.
Next i switched to 90gr 3f JSG, .530 round ball and .015 tc patches. Took 3 more shots "left side" The lone shot to the far right was from 72 yards.
I really like that JSG but with the thicker patches, i think it needs a heavier load to tighten it up a bit. Worked excellent with the .015 patches!
