After seeing the videos on youtube, we decided to try it for ourselfs. Between a 100-110Yrds shooting of the Bi-pod with this:
It was grouping at around 3 Inch and penetrating a wooden post aprox 5-8mm
this was with around 24" hold over and a .177 pellet in still conditions, IMO this would drop a rabbit with a headshot
Belive what you like and rip me as much as you want
