I was watching Tints video for the rapid fire method. I put it in slow motion, and found my cure for accuracy. Within two weeks of developing my new style (new to me) my accuracy improved greatly. Gripping the cords with my right hand, I pull the loaded pouch tight with my left hand. Stand feet slightly apart (archers style). Raise the pouch over and behind your head point in direction of target. Now pull the pouch so that it strecthes you right hand behind your neck. Here comes the fun part. In one smooth movement rotate your body at least 90 degrees so you facing target. Release the pouch and throw over hand, follow through with your right leg(optional). This takes only a split second execute there is no wind up and you could hold it at full draw for acouple of minutes prior to firing. I use a slig with stiffer cords for better control. I have ben aiming at a stake in the ground about three feet tall and two inches wide at roughly 40 to 50 yards. I actually hit it twice and 75%(roughly) of the time I'm within a foot radius. Using my old style understand or sidearm I would be lucky for an 8 foot radius. STRETCH OUT FIRST. Results may vary

wow.  40 to 50 yards with that kind of accuracy   
that's pretty awesome.  if you didn't hit the targer, you would at least scare it into submission, or if you aimed for the broad side of a deer for example you could almost certainly hit it.  that is some great news.

yeah i was thinking that too (its also the best style for me been using it for half a year and i can hit trees pretty consistantly with it )

Dork,

From your description I can get two different throws.  Both start from your "ready" stance with your left hand pulling the sling tight, right hand at or a bit behind your head, and the sling cords passing behind your head and maybe a bit above.

The first throw is essentially a Greek side-arm: as you twist to the left, release the stone so that the sling swings horizontally, pull it around with your right arm and release.

The second throw is more like a Greek overhand, or a VERY abbreviated figure-8: as you twist to the left, release the stone so that it drops behind your back, then straighten your right arm and pull the sling over to the release.

Do either of these sound like what you are doing?

I need to make a correction on the distance its closer to 30 or 35 yards. my bad

Dork,
This morning I tried the first variation I described (Greek sidearm starting behind the head).  Results were interesting: from a standing start, I was reasonably accurate.

Now, if you have watched David Taylor's videos, you know that he starts with a windup very much like a baseball pitcher: twist to the right, bring left leg up, twist back to the left and bring leg down as you release the ball/stone/whatever.  I don't do the full windup like Taylor, but I find that I do have to at least twist to the right before coming back, or I can't come anywhere near where I aimed.

With this style, however, I was fairly near my target without any windup at all.  I just tossed the ball to the left and started twisting to the left as I swung the sling around.

So now I have tried both the variations that I derived from your description, and they both work!  Very nice style(s) you have developed.  Thank you!
