Had some trouble with Goex 2f the last time out. Horrible fouling with 90gr goex and it would just start throwing them all over the place.
Today i changed 2 things, lowered my charge to 80gr goex 2f, lubed wad, 250gr REAL conicals @ 100 yards. And I started using a little extra lube around the sides of the wads. Adding that extra lube helps greatly and i felt it take "bite" in the rifling as i pushed the wad down on top of the powder before loading the conical.
3 shot group @ 100 yards with the new sights. Bulls eye is 3" Diameter. Next time i will go back to 90gr and see how she does with those extra lubed wads.
