Rather than start a new post, heres a few photos of the impact point. Etc. I ended up using an arrow with a total mass of 750gr going 225fps. Tipped with a 180gr german kinetic. The shaft was an Australian designed 250 spine arrow from native gear archery. It had a 60gr steel insert with 2 easton axis 75 gr inserts behind that. There was 430gr in the first 3 inches so FOC was pretty serious. Yes it's a touch gory but that's hunting. Yiu can see the size if the ribs compared
