Scince i haven't been useing the cannon ball molds chris offerd sorry but there to expensive for me  im not the kind of person who works a lot so i have no in come for those molds.... any way ive been using rosk i split in pecies but the rocks catch my strings (which are maid of fiber material) and ripping them to shreads... any advice on how to stop this?   (i was thinking a bout putinga weight on the release cord so it would swing outof the way faster but i don't think it will work...

well jhonny i have to break rocks because i have no other way of making ammo i live to far from a stream with rocks or the ocean and their are plenty of rocks out in my feilds so i take advantage of it. and no there aren't any small rocks in the feilds i would order som rocks from my local harware store but it costs too much for me.and i have only one tennis ball to use as a mold for concrete balls. All in all im pretty screwed thanks for the advice though.

Hey there,

I too use  rough concrete since I live near a concrete plant. I know the problem well. Here are some thoughts:

1 If you are new to slinging, your release may be a bit off which will cause tangling of the stone in the cord. I usually was releasing too early when I had that problem. I have had the retention cord ripped off my finer when heavy stones got tangled up.

2 Your motion has to be smooth. Usually if I was trying to throw too fast, it caused tangling; probably due to the "jerking and slack in the cords.

3 Also, I find that  on occation, if I sling a long stone with sharp edges they seem to get hung up in the pouch from time to time.

Even with proper technique, rough projectiles will cut away at  4-6 inches of the release cord coming from the pouch; therefore, I put duct tape tightly wrapped around the cord in this area and replace it from time to time. Or you can use whipping in this area but it is stiffer than tape.

Hope that helps

I would also suggest a different material for the cradle.  I live in New Mexico, and most of the rocks out here are sharp.  I use to use my braided slings, but they would shred fairly fast.  I now use a split pock sling with 3/4" webbing (the sling design use to be in the gallery i think), and paracord lines.  The cradle is basically 10" of 3/4" webbing looped over with a half twist and sewn together.  You can also melt the two ends and "weld" them together.  it's not as strong as sewing them, but it's faster, and mine have not broken yet.  The webbing is extremely tear resistant, and I use it on the rough stones here, and my good braided sling whenever I come across round river rocks.
