Three animals are headed directly for you ground level. Luckily, you spot them first and the wind is in your favor. They are fifty yards away and closing the distance fast. You kneel down behind the closest cover because you have no time to set up for an "ideal" ambush. Keeping your eyes on their every move you simutaneously nock an arrow. Instantly the lead animal pops around the corner at 15 yards. Not moving an inch, and looking only at the animals feet, you pray that she will just move on. She stops and and stares for a good minute. Feeling that there is no threat she calmly walks on, taking with her another animal and the "shooter" that's trailing behind. Both animals clear and the last one, still walking is now broadside and in range.
You have done everthing possible to get a shot opportunity, but now can you pull off the shot? You are not well covered. If you draw to fast or move the bow too much, the animal may spook. The jagged rock on your knees are killing you. Your leg muscle is starting to get numb and/or cramp because of the weird position that you're pinned down in. The brush infront is blocking some of your view. Your heart is racing. Etc., etc., etc.
Every spot and stalk senerio is different for me at the time of the shot. With a million things running though your mind, how do you pull off a great shot after making a textbook stalk?
So I ask you, "how do you practice for the pressure shots"?
