Simply opening the gun makes noise, but if it's done immediately after the shot the animals are still trying to figure out what happened and won't hear it, mainly because the sound of the shot is still reverbarating from the hills. The animal I shot is never the problem anyway, it's his buddies that I am worried about. You shoot one wolf, and there is usually three or ten more to contend with. Some run away, some don't. As for Bears, if they know I am there I don't shoot unless it is an emergency. At that point the more shots I can get off the better. I don't want to have to reach down and remove an empty, I want that empty gone, so I can drop in a fresh round and close for another shot. That is why I quite carrying my TCR, cold fingers don't remove cases well if at all.
