SCI Record Gemsbok
I used a Mathews SoloCam (67lbs), Easton Carbon Arrows, Cobra release, Satellite broad heads. On my Gemsbok, I was stalking, I probably wouldnt have been able to get a shot off if I wasnt able to hold my bow at full draw for over 45 seconds (which seems like forever). I never thought to practice this.
My Gemsbok was walking right at me about 120 yards away. I drew when he was behind a tree so he would not see any movement (especially the Gemsbok, they are the hardest plains animal to get because of there eyesight is amazing) and
held it until I had the perfect shot.
