Can you show an ideal (approx is enough) Width / Taper / Elongation Ratio-(Active Length) / Thickness / PER ammo?

It looks like the info you are seeking might be at the lower end of his data. He addresses the active length question as follows.

I don't include the actual length of the band in the results for 2 reasons.

1). We all have different draw lengths.

2). The band length could be 10mm or more out because of the natural stretch increase over time.

Besides, we all know when we have pulled the band to or close to maximum stretch.

The following subtitles rank the bands from fastest downward. If you want the fastest in each category then it would be the top band listed in the desired category. If the draw weight is a bit more than you prefer then move down the category list until you find the highest speed with your acceptable draw weight. This method of ranking in categories will help you to easily find the band with the fastest speed for your desired max draw weight.

Hope this helps

Hey Tremoside - I am not sure you have understood the purpose of the thread.

Obviously, we all know about the 5 points that you have mentioned in the centre of you post, thats a given, You could point out a lot more too, that's easy.

Now as everyone knows, Northerner has been the king band tester here for years. Thankfully, he has become a great supporter of this thread.

Now, because of all his years of experience in band testing, people will have realised by now that whenever I say something in a post, he has a way of saying it better.

So I am just going to skip my words and use his words from a comment above, to describe what this thread is all about.

'It let's us see what happens with changes to various band thicknesses, widths and ammo weights.'

There is no way I can say the same thing any better. That is as clear as you can get.

So if you are using Precise 0.50, and you are wondering if 0.60 will fulfil your needs any better, then the set of data can give you an IDEA.

If you are using SoBong 0.65 and are wondering how the FPS compares to Sumeike 0.65, then this set of data can give you an IDEA.

If you are using a 1 - 3/4 taper and are wondering how switching to a 7/8 - 3/4 taper will affect your FPS, then this set of data can give you an IDEA

If you are using a 7/8 - 3/4 and wondering how this compares to a straight 3/4 - 3/4, then this set of data can give you an IDEA

If you are using 7mm ammo and wondering how the FPS may change if you switch to 6mm ammo, then this set of data can give you an IDEA

If you want to know the difference in draw weight between SoBong 0.45 and Sumeike 0.45, then this set of data can give you an IDEA.

If you want to view a list of certain band cuts, and see which one offers the lowest draw weight, then this set of data can give you an IDEA

This is just a small sample of what the set of data has to offer.

But this is where the journey begins.

You now have to test to make sure that you are happy with your draw weight and band life, and maybe reduce the active length accordingly.

You also need to make sure that you are receiving your desired FPS.

Bottom line, you still have to test any changes you make to your combination of band thickness, band cut, draw weight and ammo size until it fulfil your needs.

The thread can also help you to choose the latex that you want, as well as saving you money by avoiding the latex you wish you hadn't bought.

Because usually you buy the latex first and then get the numbers second. This set of data provides you with the numbers first instead.

If I gave this set of data to 100 people and then told them to put a band set together for their own personal needs, I bet every band set would be different.

The combination of latex brand, thickness, band cut, draw weight, FPS, ammo size and active length would all be different.

But it would fulfil their own personal needs.

That is what this set of data is designed to help with.

Now I see that Northerner has managed to post a reply to you already, which is great.

So, I hope that between the 2 different angles of our replies, you are happy.

Thank you Northerner!

It is much easier to handle the information once a brief summary is out.

I guess I can cut my bands already, but watching this thread I thought the amount of data is simply overwhelming and misses the attention of the target audience.

My intention was nothing else, just driving attention to the presentation. Like chunking the data based on importance and real life. Instead of presenting the sheer volume. Thinking of 30mm straight cut for 6mm ammo for example.

Thanks for the wrap up again!

Hey Tremoside,

As you can now see, I crunched all the data and then created the very summaries that you were looking for, at the very end of the thread.

I presumed that you had read the thread, and so further presumed that the summaries that I had presented, were not the summaries that you were looking for.

This is the reason I chose to answer your post from a different angle.

You are right, it is much easier to handle the information once a brief summary is out, which is the very reason why I wrote those summaries.

You say that watching this thread you thought the amount of data is simply overwhelming. Again, you are right, which is another reason why I wrote those summaries.

You say it misses the attention of the target audience. I ended the thread with those summaries to make sure that this would not happen.

You say I presented sheer volume, and once again you are correct. Which is why I purposely ended the sheer volume with those summaries.

I am glad that you are now on board.

By the way, if you would like to download those summaries in word documents, then I have left you the 3 links below.

I'm sorry, now that I look through the numbers much more carefully it seems our results may not be too far off. The last two or three tests I did didn't include the lead equivalent to 9.5mm but depending on a few things they've usually been around 30 fps apart, about 40 fps with much higher elongation.

Plus, with all those fun numbers in one place it's likely I may have misread something. Also, thank you for all the information. Numbers are like candy for the mind

Hey Projectile Pilot - You are absolutely correct. You will have experienced more FPS than me when using a handheld slingshot.

Now, it has just dawned on me that I have never mentioned my last day of testing, where I enjoyed the fruits of my labour.

As I approached the end of my testing project, I purchased 12 dirt cheap plastic slingshots from china.

Now, they only cost about £2.60 each but they fit perfectly in my hand, so I was very happy.

Once I had crunched all the data and wrote out all my summaries, I then loaded all the 12 winners onto my 12 slingshots.

This means that I looked at the Sumeike summary results, and then loaded the fastest band cut for 6mm, 7mm, 8mm and & 9.5mm ball bearings.

I then did the same with Precise and SoBong. This is what I mean by the 12 winners.

Then on my last day, I just went crazy. I just kept rotating these slingshots and shooting these crazy speeds. I couldn't stop.

The candy shop door had been left wide open, and I wasn't leaving.

Now where this relates to you, is that I too was experiencing higher speeds. I also did mention in the thread that you too would experience the same.

Firstly, I was using a smaller aerodynamic pouch instead of the large testing pouch meant for 10-13mm ammo.

Secondly, this time I removed the excess 10mm or so excess latex flap from the pouch end, which I didn't do during testing.

On top of this, I was sometimes subconsciously flicking my wrist forward, sometimes drawing a little further back, and sometimes releasing the pouch a bit earlier.

Now this all combined to result in my higher speeds.

If you now include your longer 32 inch draw length as opposed to my 30.5 inch draw length, your results are right on the money.

Remember, I used a testing rig so that I could not accidently or purposely push the FPS higher.

This way, my results would be consistant as I was able to compare oranges to oranges and have full confidence in my results.

If I had used a handheld slingshot, then my results would have been all over the place and I could not have trusted my results.

This is because I could not trust myself to replicate every shot exactly the same.

Now, the combination of all the testing, compounded with the final day of crazy shooting made my pouch pulling thumb sore, feels more like a sprain.

So I haven't done any shooting since, I will wait until my thumb feels better.

So I am glad to hear that people such as yourself are making the most of the set of data.

When I finished the set of data, I wasn't too sure whether anyone else would be interested in it.

But then I thought it may help a few biginners, who usually ask questions which are answered within the set of data.

From all the feedback that I have received on the comment section and on PM, I believe I made the right decision in sharing this set of data.

It's been a little while now since you posted your test results, and so I just gotta ask this question.

Based on all your testing, if you had to choose only one band, one which fulfilled all your own personal needs, which one would it be and why?

thanks secret stallion. I am using precise 3rd gen .75, have been thinking of going to .65 on your findings. less band weight more speed maybe, for 8mm steel and 6mm . the .75 is very snappy, I found and if you don't cut it right it doesn't perform as it can. what do you recommend secret stallion regards robbo

I'm looking forward to his answer. Maybe your question should include your max draw weight. I shoot 6, 7 and 8mm steel ammo but I like a lighter draw weight so I'm thinking of .45, .50 or .55mm Precise Gen3. With a 32" draw length I should be fine.

hey northerner. got a short draw mate 26 to 28 inches. with big taper, band life is a lot better than TheraBand gold .supposedly .65 3rd gen is better than tb and about similar thickness.in the video s ive seen and read about , most say it is.

If You shoot 8 mm steel, try Precise 0,45 (1"-3/4").

Light draw and enough speed to suspended card cut from 20 m distance.

With that cut it's really long lasting bandset too.

Hey gunslingster,

Short Answer - Sumeike 0.45.

Long Answer - The reason why I can now answer this question is because I recently challenged myself to answer this very same question.

My band supplier recently had a promotion where I was given the opportunity to turn all of my reward points into product.

If it weren't for this promotion, then all of my reward points would have probably expired worthless because they are only valid for 4 months.

So I decided to cash in my reward points in exchange for an order, which included a few rolls of latex band.

For the time being, I wanted to choose and commit to only one latex band.

So in order to choose the perfect latex band for me, I simply wrote down a list of criteria.

I will list the criteria that I can remember:

During my testing, I became less keen on thick bands because of the heavy draw weight.

Heavy draw weight made my pouch gripping thumb ache / sore after a while.

So I wanted to use light bands with light draw weight.

I do not want to use heavy ammo because I like to use 6 and 7mm ammo.

I only need enough FPS for my 10m target practice.

I do not shoot any further than 10m, and I do not hunt.

I like to attach the bands to the pouch by using a constrictor knot. This works perfectly well for thin bands, but in my experience, not for thick bands.

I don't care about band life.

I cannot remember any more criteria, but you get the point.

I then looked through my test results and Sumeike 0.45 was the perfect choice for me.

Now for full disclosure, I always wanted to try Sumeike 0.45 anyway because I had heard great thing about it.

I know that there are experienced 10m target shooters out there, who have tested various bands and ended up settling on Sumeike 0.45.

The only example which comes to mind at the moment is Asa at Romany Catapults.

And of course, we all know that the 2018 Chinese World Champion uses it too.

But my choice of band came from identifying my own personal criteria / needs, and then allowing my test results to choose the right band for me.

After all, this is exactly what the test results are for.

If you are interested, I currently use a 3/4-3/8 (18-10mm) taper.

My active length is currently 145mm.

It is plenty powerful.

I use 6 & 7mm steel ball bearings.

The average band life is about 150 shots.

I mentioned above that I don't care about band life, which may seem unusual to some people.

Now, let me explain the 5 reasons why:

* My latex band is not expensive.

* I enjoy making my own band sets.

* I have a Band Cutting Template, which is specifically made for my sized tapered bands.

So I can quickly cut 5 pairs of bands at once, or even 10 pairs if I double up on the band.

* I can quickly attach the bands to the pouch by using a constrictor knot.

* I can quickly attach the bands to the forks by simply slotting the bands into the fork tips, and then just tighten up the thumb screws.

I hope I have fully answered your question.

Hey robbo,

If you are thinking about going from 0.75 down to 0.65 in order to reduce your draw weight, then you won't really find much difference in draw weight

for your 6mm & 8mm ammo. It is still going to be around 11ibs.

You currently shoot with a 17mm - 9.5mm taper, which is very close to what I am currently using myself, so I would drop down even further.

I currently shoot with a 18mm - 10mm taper, and my draw weight is around 6ibs or less.

View the test results for 3/4 - 3/8 and compare the draw weight between 0.45, 0.50 and 0.55 and see which draw weight is for you.

As long as it also has the FPS that you are looking for, then you have found your band thickness.

Then you will need to see if you are happy with the band life.

I have just posted a reply to gunslingster, and I believe it would be a great idea for you to read it.

Also, I have just read the replies from both Northerner and Kalevala and they have nailed it.

So I believe that between these 3 or so posts, you will find exactly what you are looking for.

By the way, I have found both Northerner and Kalevala to be incredibly experienced and knowledgable.

So if I were you, I would take any information that they offer, print it out, place it in a nice gold frame,

and then hang it on your favourite wall!

Just Sayin'

Wow, I thought you were going to be a bit more pc and not commit to an answer. I wasn't expecting all that, thanks man!

So is that the reason why you are selling all your other bands, because I thought you would have just used em up.

I'm sure I read that you purposely bought a little extra because you wanted to carry on using them after your testing project.
