I shot a gemsbok at 145 yards with a .50 caliber muzzleloader. I told my PH that I wouldn't attempt anything longer than 140 yards. I had practiced extensively with the gun before going over and felt that was my limit. Anything longer and I refused to shoot. I had perfect conditions and a solid rest for this shot after a hard day of tracking. My PH worked hard to get me within range on all my game.
