    Why is it that people that is heavy bands like for emample 4 layers of theraband gold use big ammo and deprive themselves of power instead of using a 20mm steel or lead ball and get around 100 fps when you can use 1/8 inch steel and get around 300 fps with high penatration. My point = Whith heavy band use very light ammo .

    By using Joergs Thera Band Calculator you can find out what bands suits best for the ammo you want to shoot. Just adding more rubber wont give you more speed. To match a heavy draw you need heavy ammo. The good thing with rubberbased weapons is not the the speed, its the ability to shoot a wide range of different ammo, and that you can shoot heavy ammo. Using to much ruubber with to lightweight ammo do actually slow down the shot, plus it gives you a painful handslap. The key to more power is long acceleration and to keep the rubber in stretched out condition for as short time as possible.

    using heavy bands with light ammo is like dry firing rimfire guns or bows. it will cause damage.<br><br>multiple layers are only needed for heavy ammo. bands don't snap faster when you put on more of them.<br><br>more fps does not mean more penetration.<br>how many joules you get is important and that's depending on weight of ammo AND what bands you have.<br><br>but more joules does not mean more penetration, because that depends also on the shape of the ammo.

    I dont think slingshot bands get damaged from dry firing, thats why the Raptor is able to shoot such lightweight ammo!

    <span class="postbody"><br><br>thats right! very important to find the right bands for the ammo. shooting 8mm steel with a 3 layer bandset is nonsense. <br>jörgs band calculator is the best tool to figure out the band dimensions... <br><br>the bands last longer and have the best performance and shooting comfort! </span>

    I think the heavier bands cools down faster as they got more area thats affected by the room temprature.<br><br><br>

    Why would you like to pull 3 layers to shoot a certain ammo when you shoot the same ammo at the same speed using 1 layer.<br><br>3 layers don't shoot faster that 1 layer.<br><br>But you can shoot a heavier ammo with 3 layers.
