Contratulations on the second doe.. That Genesis is kind of paying for itself real quick. Those FPB's I was looking at the other day when I was at Wally World. They kind of remind me of a pointed minnie ball. With that hollow base, it must expand and then the copper grabs the rifling of the barrel.

Have you noticed any copper build up or are you giving the barrel a solvent brush treatment to make sure that does not happen. They sure sound like they shoot well and they do a lot of damage. Again, congratulation on the doe.
