It's about the torque vs speed... At the thick end the band pulls hard but slower, which is great for starting the ammo moving. The further toward the thin end, the faster the band is contracting but with less force and that's great for accelerating. Think about car gears, you start in a low gear to get the car moving and as you go faster you use higher (faster but less torquey) gears. A car that is either stuck in 1st or 5th gear isn't going to win a drag race. Similarly a straight band is pushing slower as it contracts but a tapered one can keep applying (at least some) extra force because it is not contracting evenly over the length, which means the ammo is correctly "powered" torque wise for a more of it's journey beween the pouch and forks.

I calculated that both the tapers are 40% and as you mentioned you too had the same problem. I understand a broader taper should solve that. Thanks for your wonderful videos.

Lol I'm not really a sciency guy but I gave it a shot🤓

Here is my theory on the results of the different tapers: The 24-12 has a faster retraction speed than the 24-18 due to the narrower taper. However since it has less band material, there is less mass making it more susceptible to the heavier ammo's inertia. The 24-18 on the other hand might have a slightly slower retraction speed but its heavier nature will be less affected by the heavier projectile. However when you have a lighter ammo the thinner taper is able to stay truer to its retraction speed as there is less inertia to fight through. I'm just talking out of my ass though I could totally be wrong.

Man I am REALLY liking your channel & your great content & of course I thank you for it. I just recently got back to using slingshots as I am now retired and enjoying my "2nd childhood"!!! I also have gotten into archery and to put those speeds in a comparable perspective...a 45lb draw weight bow & a 300gr. arrow gives you somewhere between 160 -170 fps...a 50lb draw weight bow will get you around 170- 180 fps with same arrow...these are approximate speeds but pretty close as different set ups and strings will alter just what speeds you will get. Just a little input so you slingers out there can get an idea of just how well the band's of today perform in comparison to the sport of archery...the form & repeatedability are pretty much identical in both shooting sports...friends and neighbors of mine seem to be quite surprised that I use the same style of shooting for slingers & bows...some almost cringe when they see my draw length on a slinger is the same as a bow...makes perfect sense to me.I have always enjoyed the shooting sports and have an extensive collection of air guns also...when you retire you will find it hard to have more fun than I do...so, at the very least, get yourself a good slinger when you retire and have a blast.If you are into air guns those metal sculptured lawn decorations make awesome air gun targets for plinking in the bush or anyplace else you can shoot outside. To my surprise, those light metal lawn decorations will take hits at even 10 yards from a high powered air rifle shooting .22 slugs!!! They don't do so well with steel ball from a flipper though!!!

This is an awesome video, super informative! The energy in the bands needs to move themselves through the air and the projectile. The heavier ammo is demanding more energy and the thinner tapers can't keep up. However, for the 3/8 steel, if you cut the same tapers with a .6 or .65 band I would guess the results would be more similar to the 5/16 outcomes you showed.

Your videos are very useful and an excellent source of real stats -the numbers don't lie. I appreciate how you keep the same type of draw and max out the bands on each test, always factoring in the active length, as it eliminating some of the variables. I just watched a dude test a bunch of bands, anchoring to the side of his mouth, and then to make his point on his favored bandset, he switched to longer bands and a half butterfly draw, which invalidated his comparison. Thank you for NOT doing silly stuff like that and your straight forward presentation!

The active band length were the same and they all seemed to stop at the same spot. Yes I shot the 24-12 better than all the rest, in the warm up and the chrony test even though I am just putting the fork on target not aiming through the chrony. I believe this is due to the draw weight. Easier to hold, less hand fatigue and lighter smoother draw will give you better accuracy.

Absolutely brilliant! With your ingenious striping test, you Sir have demonstrated with just a few strokes (pun intended) what years of mathematical modeling could only hope to grasp at. If I understand correctly, you were pre-stretching the bands with a few warm-up shots before doing the actual test. Good move. I notice that the spread in the measurements within one taper were wider than some of the differences in between the tapers. One way to perhaps reduce that effect would be to increase the sample size.. to say 10, or 7 as a compromise. May I request 25/20 and 25/15 as these are very popular tapers for heavy bands? As for the third taper to test.. perhaps 24/12. That half width taper brought about a surprise in this video. Maybe it has more to reveal... Thanks for your wonderful video. Subbed 🧐 🤓 😎😄

@@ATOMark Most definitely. Wonderful plan :)

Wait a minute here, now you need to try straight bands on both the 3/8 and the 5/16. That should be interesting, and then compare that with the 2 tapers you did here.

The acceleration will be limited by the lowest spring rate to weight ratio. Spring rate being proportional to band width for constant thickness bands. Say the ball and pouch weigh 150 grains, and the weight of the active bands weigh 50 grains. The taper ratio for best acceleration would be 150 over 200 or 18mm and 24mm. If the ball and pouch drop to 50 grains with 50 grain band weight, it would seem the optimum taper for maximum speed would be 50 over 100 or 12mm and 24mm. The lighter the projectile, the more the taper. Note that the above was based on a constant bandweight per length of band. When you taper the band, that changes the assumption, and you could do more fine tuning, but you end up with a curve rather than a straight taper.

Makes sense. Less rubber, greater tension/stretch, more speed (If my understanding is correct). I guess it’s really all about trade off’s, and personal priorities. More importantly, thanks for the video and for the visual comparison, it really helped me wrap my brain around what’s happening with the taper. I shoot 5/16. Not for any reason particularly. I just bought 1500 of them and realized after how many 1500 really is 😂.

22-18 taper is what I use. I would like to know ha fast and best ammo size, if you could. “Thank you”, Jim Payne, Charlotte,NC.

The smaller bands could not accelerate the heavy bullets o well, because in principle the speed becomes higher the larger the ratio of the dimensions of the bands is. so 25-15 will be faster than 25-18, but if the amount of latex is not sufficient to accelerate heavy ammunition, the principle changes. That is why the 5/16 was faster with the large dimensions.

I have been thinking about this recently. I’m trying to get the perfect balance between speed and pinch weight. Narrower tapers should be faster. I agree with smo that the same tapers with thicker elastic will give the ‘correct’ results with heavier ammo. Trick is, how many shots can you shoot accurately in a row with a heavier draw weight?

@ATOMark

2 жыл бұрын

This is the thing. I see many people shooting 25-20 tapers for 9.5 and 11mm steel I have proven yhat 25-15 tapeer is lighter draw and faster speed. In my opinion 25-20 tapers should only be used in cold temps when reaching certain speeds are important like hunting. Aside from hunting bands should be made with the lightest draw possible to get your ball down range and hit your target consistently. There is really no reason to max your bands out increase your bands draw weight to target shoot. Getting back to hunting shot placement is most important. Suppose you can get your 9.5mm steel to get to 300fpswith a draw of 14lbs maxed out. But if youbadd 1.5 cm to your active band length your speed would drop to 275fps but with a draw weight of 9.9lbs. You will have a band set that shoots more accurate , plenty fast to take game, lighter draw. And longer lasting bands. Win, win and win! In my opinion! In the end tapered bands can increase draw weight and speed but there is a sweet spot for each ammo size too much taper for heavy ammo will slow it down and so will no taper. By adding and reducing active band length can help fine tune band speed and draw weight to suit your needs.

It crazy it goes against the laws of physics but its right iv found with a 60 and 8 mm steel 23/18 22/15. 20/15 18/12 the 18/12 is normally the fastest

Well done, man! Please try 7/16ammo.

@@ATOMark Hey! how's it going? I don't know how thick the bands you used for this video are, I'm guessing .5 mm or .6 mm, I'd love to know what kind of results you get with the same tapers you used, just testing additionally the 7/16 steel ammo. I normally use .7mm thick bands, 22mm to 18mm taper for this size of ammo. I wish you the best!

I used. 55 bsb for this video. They would be far too light for 7/16. I will be doing a video with 7/16 ammo and testing tapers aswell soon. But for those I will use minimum .65 most likely .7 for that size ammo

Did you measure the draw weight 24-18, 24-15 and 24-12 for these bands? Based from your test, 24-12 can shoot faster small projectile than big projectile and for 24-18 shoot much more faster heavy projectile than the small projectile..

I did not measure but there is a noticeable difference between the draw weights. The 24-12 is lighter than the 24-18

Slingshot bands retract quicker with a smaller fork gap.

For heavier ammo use 50% taper but thicker bands .7 or .8 and you will have crazy speads.

I would use 18-12. It might be a fun experiment to try 15-10 just to see what the longevity would be like. Usually I set up with 18-12.

@@ATOMark Do you ever heard and test the 'sumeike' brand ? Just wonder how does it compare to the precise. im tried to find the best rubber setup and brand but dont want to order each of it to try, because 2meter rubber roll will be too much for me to use each of it and im now already have the sobang .6 and precise .65 that look like it will take forever to use it all, lol... overall what is your favourite band setup for shooting the 8mm that produce decent speed and performance ?

I think with a .55 latex and 8mm/5/16 ammo a slimmer taper is faster. Like 18.10 , 18.12 Cheers Sis ❤

so what's the difference and What is the effect on speed with true tapered vs semi ( once side flat ) tapered vs Sharpened Taper?

@ATOMark

True tapered and semi tapered are the same thing. Whfm you check the dimensions there is no difference. As for the sharpened tapers I saw only about 10fps difference with the 25-20 template I had. I would like to try this again with a more drastically taper like 25-15 or 24-12 and see.

I know . I had this question a while back from bands made with a taper ruler. Both bands were the exact same 24-12 just the very ends were not perfectly straight. I tested them on thr chrony and could not find any noticeable difference.

So, it seems like extreme tapers are good for light ammo but for heavier ammo moderate taper gives better results 🤔

@ATOMark

It is most likely that the band was too light for 3/8 for maximum speed in that weather. I will do another test with .65 , .70 or .75 with 3/8 and 7/16 steel

A wider fork increases the draw length... the bands will be stretched further to your anchor point. Your anchor point will also be lower with wider forks. Hope this helps 👍

When the forks are closer together the band retracts quicker, hence why pickle fork slingshots have a higher FPS with the same rubber setup than a wider fork slingshot.

@vincentement usually beads perform best at 20°c + the colder you get there is a drop off in performance. I have found that anti cold bands are kinda a gimmick. I prefer to go up in size when dealing with cold. For example if I shoot .45 or .5 in summer I will shoot .6 or .65 in winter.
