<div>Now ive learned that you should NEVER dry fire. Whether its bows, or slingshots. Now i NEVER dry fire, however i was just curious, specifically for rubber, why you shouldn't dry fire. Ive never really heard any real scientific explanations? Im just curious, strictly for scientific reasons. <br><br>Another thing. If shooting light ammo is supposed to be bad for you bands like dry firing, then is there some sort of ratio we should be following? Like I know Jorg has his TBG calculator, but still. What is a good ratio for firing lighter ammo (or in my case, light glass marbles). I want to know, mostly so i can get more out of my band-sets, seeing as they break too too often. (I associate premature band life's to shooting light ammo...)<br> Thanks guys <img src="http://illiweb.com/fa/i/smiles/icon_biggrin.png" alt="Very Happy" longdesc="1">

I know that if you dry fire a bow the string can snap (and in my personal experience cut the crap out of my forearm) and it hurts. Never had it happen with a slingshot but it should probably be avoided. From what I have been able to gather from posts by Jeorg and other knowledgable members of this forum if you want to shoot lighter ammo you should lighen up on the rubber (more power = more strain on the bands i'm guessing) or shoot heavier ammo. I'm sure another more seasoned slingshot user can provide better advice then I can.

to reduce the risk of band breaking use less tapering or don't fully pull back when shooting (cut bands longer). sure, you will loose power. thats the downside but the truth.<br><br>i have many explanations why not dry fire guns and bows. when it comes to rubber, that's just what i experienced. i think too fast contractions without resistance is the reason of that. wish i spent more attention to the physics teachers in school.

<div>Yeah i feel the same way, i dont know why it happens really, but every time i shoot my marbles, my bands dont last 50-60 shots before cracking and eventually breaking.</div><div class="clear"></div><div class="signature_div">

What kind of bands are you using/what dimensions do you cut them to, also do you know they size/weight of the marbles you use? This info will probably help someone give you pointers on getting the most out of your bands.

<span class="postbody"><br><br>ahem.., that were just examples like how old are the bands, were they always stored in a dark cool room and were treated with talcum powder, ... did you use a roller cutter ...</span>

The pouch side is normaly the location where the band break. What I would try is to cut your bands straight ( no taper) and eventually decrease your band width to find out the right force you need for your ammo.<br><br>I can imagie that will help the band life. <br><br>I'm experimenting myself with ammo weight and the right rubber for it. <br><br>For my marbles I know that a 2-strand setup 1745 single tubing is to less. A 4-strand setup 1745 is too much.<br><br>A 2-strand setup 2050 seems to work best for me with my marbles. <br><br>With TBG I still need to check. I mostly shoot tubes because they last longer.<br><br>Every shooter is different and every shooter need to find his own 'personalized' setup. IMO

<div>Hahah. I keep the NEW bands in my drawer under my bed. Its pitch black and AC'ed lol. I have never heard of treating them with talcum power! Should i try that?! I have access to it in my Metals/Jewelry class at school.</div><div class="clear"></div><div class="signature_div">

The band calculator is the best advise I can come up with, really. <br><br>Dry firing isn't a huge problem for rubber, but you will get really nasty handslaps - and the rubber will tear maybe even sooner.

hello,<br>Now that i do( try to) make a smooth finnish on the forktips, using only latex stripes at the fork and at the pouch my bands last longer. At the very begining i was using a string to tie at the pouch and the bands broke at that place everytime. Now i can take between 300 and 600 shots, i don' t count them anymore but it can be more.
