I have killed 8 this year on our 80 acres and 3 of them had mange and looked pretty rough. I put a 20” 204 barrel on my ar and really like it. I use a thermal and judging exact distance is hard. The 204 flat trajectory helps a lot. And the accuracy and low recoil helps a lot too. I had a ba 1:7 18” barrel before. I like the 204 much better and I don’t miss as many now.
