.22 long, .217 23g H&N slugs, 935'ish fps. 100 yds. Big fatty too. I knew I connected but as the grass was kind of deep, and I was below him ... I didn't see him when he initially went down. I kept looking through the scope and then saw the "helicopter tail". Booyah. I took him off the roof of the car which you can see down near the farm equipment. #8 on the year, #3 with this Taipan.
