Max strech of bigshot

Does anyone know the maximum stretch one should load the new designed big shot head? I ordered one from a distributor with the recommended length poles (three 3 foot pole sections) and it seems that after a day of shooting, the connection between one side of the firing pouch and the black surgical tubing is beginning to tear. It is to rubber tubing itself that appears to be tearing, but I can't be sure because the original holes put into the tubing to connect the firing pouch to the tubing are kind of ragged. So anyways I was wondering if I misused it by stretching the big shot to 9' or if I am imagining the tearing or that possibly my new toy was becoming a dangerous toy. Any thoughts or past experiences welcome.

I use 2 4' sections and draw to about 6-1/2' or 7' usually... worth about 75' with a 10 oz shot bag. Haven't had any wear issues yet. 9' sounds a little long but I really don't know what the limit is supposed to be.

Sounds like you might've gotten some bad rubbers.

I use the two four foot poles. Probably the furthest I've ever drawn it back was 7.5 feet, and I did that several times while using it for "extracurricular" activities. The big shot will easily shoot a 10oz bag well over 100ft vertically at that extension.
 
When I think about it I'm getting 100' of loft out a 6' or 7' draw, it's just that I don't shoot at crotches higher than 70' cuz I go up on 150' of doubled down rope... but that ball does usually shoot waaay over the crotch.
 
The Big Shot tubing DOES have a limit to how far it can be pulled, pretty much like any sling shot. I would not advise stretching it to 9-feet or any distance that requires two people or a pole longer than the recommended 8-foot version. As illustrated in the sales literature the Big Shot is designed to be pulled a comfortable distance (3-6 feet) with one hand by a single operator to easily launch a 6-10 ounce weight 100 plus feet high.

If you're using a heavier weight, like 16 ounces, with thicker or heavier line I would recommend stepping down to lighter artillery to solve potential problems. Thanks for asking and good luck shooting!

Also, if your tubing is indeed cut with a jagged edge as indicated please call OUR CUSTOMER SERVICE DEPARTMENT and we'll get it switched out.

Thanks for the responses. Thank you Tobe for the official word. I was over stretching the big shot by pulling it to just under 9' (did you know that it can hit 220 plus vertical feet with an 8 oz bag and 17 lbs test mono on a spinning reel). The firing pouch was tearing the surgical tubing, because it failed today. I didn't know that 6' is about the max stretch that it should be put through. Lesson learned. Time to get a crossbow. Are they legal in master challenges?

Tobe,

I'm on my 3rd set of rubber tubing because the ends keep unrolling. Here's a pic of what it looks like:

Sherrill has sent me two replacements (no charge). I sent the first set to Sherrill for inspection. I am not over stretching; I don't think I've pulled it longer than 5 or 6 feet at the very most.

I deeply appreciate's Sherrill's response to my problem, but I would like to know what's going on and avoid future occurances. Any thoughts?
 
Ron,

I've not seen this before and suspect that you might be cocking into a Wichard trigger. Is that the case? If so, I suspect you do it as I do by grasping the rubbers just above the pouch and are inadvertently stripping down the girth-hitched tube end. Otherwise I don't know how it would happen. Again, this is the first report and if you've had it happen 3 times it's likely to be something in the way you fire. If you're not using a trigger yet somehow pulling above the pouch, try pulling only from the pouch strap below.

You should be able to solve the problem I see by simply milking the tubes back over the hitch.

If someone else has had this happen could you chime in with the cause?
 
The same thing is happening on one side of the one I use at work. I have tried to milk it back to no avail (that tubing cinches pretty tight). We don't use a trigger or anything like that. The odd thing is that this BS is only 2 years old.

as far as a cause, your guess is as good as mine!
 
Tobe,

I do use a Wichard trigger, but I do not pull the tubing from above the pouch. I have a 3:1 pulley system to pull the pouch downward. I connect the trigger to the pull strap on the back of the pouch, pull the 8mm cord to stretch the tubing and a Blake's Hitch captures the progress. So I am sure that I am not stripping the girth hitch.

Apparently you've never tried to 'milk' the tube back over the hitch - LOL - it's near impossible and I had the same success, which was none, that Zac had trying to milk it back.

This has happened twice; I have a third set, or the second replacement. I have not installed the third set yet. I'm trying to get all the mileage out of the second set and I'm just about there.

I sent my first set to Sherrill Tree and you should be able to take a look at it. If you find a way to milk the tubing back into place, please let me know about it.

I'd very much be interested in the manufacturer's thoughts on this.

I can't help but think others have experienced this and didn't think it unusual. But that's totally unsubstantiated.
