Dravonk,
Entschuldigen Sie mir, bitte! I wrote too hastily. What I should have suggested was certain parts of Mr. Forsyth's article, not the whole thing. I myself do not practice loading my sling one-handed. But I do pay attention to his description of the actual slinging style:
Quote:...stand very still while facing your prey with your body at an angle of about 45 or more degrees. .... Keep the throwing arm side of your body to the rear, hidden from the target's line of sight. Hold your visible arm close to you, across your body. ... Without hesitation and without moving a step, very quickly swing your arm and sling up from behind you and over the top in an overhand throw while attempting to keep your arm as straight and long as you can for airspeed. Put your body fully behind it in a fast turning motion similar to a baseball pitcher but without the step. Be aggressive and make all motions as large as you can. ... The whole action is over from start to stop in less than a second and the arm has swung less than 360 degrees. If your muscles are not used to this motion, start slow and work up to speed over a period of time. Speed and accuracy will only come with daily practice.
You said that sometimes you hold the loaded pouch in front of you, instead of starting with it hanging behind you. There is nothing wrong with that, it is just another style. Some time back, one of the members wrote of visiting a woman who had been a shepherd in her youth. She took him out back of her place, and demonstrated her style, which went something like this: Start with right hand in front of you, holding sling cords, and left hand out to your left side, holding the rock. Toss the rock out to your left (toward the target), moving the right hand so as to allow the motion. Then draw the right hand back, pulling the stone and pouch back as they fall, then whip the sling back, up, and overhead. The latter part of this style is very much like the Apache style; this one just starts differently. The old woman had killed a large number of coyotes during her shepherding days, using that technique.
Perhaps the wisest thing for you to do is tell people like me to stop suggesting things, you will ask for help when you need it.
