That FPB load sounds lethal for any hooved North American game. Good luck with it.

They are definitely not a bullet for fun shooting, but they are a very good hunting load. They seem to shoot to the same POI from a clean or dirty barrel for me too. I have experienced the same ease of loading on a dirty or clear barrel. My groups were 1" at 50,but I have not shot it at 100 at a range. I did shoot a deer at 80 yds though.
