Well I have dat a .20 Tactical for a few years. I have shot it a bunch the last 3 years. I have only killed paper. I have worked up several loads with different bullets. I decided to take it ground hog hunting. I let my son (13) shoot the first ground hog with it. 125 yard shot. I let a buddy make kill#2 with it. 185 yard shot. Fast forward a few weeks and now it’s my turn. 345 yard kill. I’m pretty tickled with that kill at that distance.
