For an interruption test I would suggest some small bushes/leaves in front of a target to simulate real obstacles you might want to shoot through. Water just has way too much stopping power (it stops real bullets fairly quickly too).
I’d do a few pages of paper or cartons. You need some kind of standard and putting brushes or leaves seems way to random. But I agree water might be too hard cause if it already Stopps real bullets you’ll probably loose a lot of detailed info with bbs
I agree that a wind tunnel would be a nice way to measure dispersion. It would be the most similar to actual usage effects, but could be difficult to make long enough unless you have a homogenous high flow rate of air. You could create a tunnel to isolate from the external environment and use a kestrel (maybe you could get a sponsorship, learn how to make a clone of one, or borrow one from a shooting buddy) or something to measure wind velocity. You would need to make sure there is no wind on the back of the fan to cause varying windspeeds.
Great content guys! Love watching your new videos. Glad to see the channel growing quickly! Perhaps consider building a wind tunnel type thing where you can use a fan and control the wind speed to simulate shooting in different wind conditions.
Aces High RC & Airsoft thanks buddy love the idea! We are working hard to get the channel grow big and yes we would love to build a 100m range tunnel where we can control the wind and so on so. It’s a long way but it’s the only way! Help us to get big would really appreciate the help and support!
@@4UADSmartAirsoft Im new to modern airsoft, and I love that there are dudes like you so passionate about the sport. Ive got the airsoft bug pretty badly, and im glad I get tons of airsoft youtube vids to scratch the itch until the next time i can get out on the field.
Gnievv we actually did that for the pre test, it was really fun to see different weights of bbs would have a different depth when it hits the jelly, however we took that out because it really took too much time time to make jelly. For future mass production tests we won’t be using the jelly, however I think we can make an episode for it! Still thanks for the suggestion buddy! Really appreciate it!
Jelly can be made to different densities. Standard ballistic gelatin follow an FBI protocol for density based on live targets. Lighter densities can be used as a medium when not attempting to recreate effect on live targets. However, gelatin is more dense than water in general and the BBs would penetrate even less. Fun idea, but this would be hard to measure due to the short penetration depths.
@@4UADSmartAirsoft This is a HUGE topic rigth now in the spanish airsoft comminity, with big channels making experimentes trying to prove one thing or another, nothing conclusive yet.
From your tests the best BB with the most hits and highest accuracy was the 0.28g. Where the 0.40g had the lowest hits that were on target, even though they had the closest grouping. (this comment is just about the first test)
I that there is an ideal bb weight for every airsoft gun. Over that weight, the hop up will need to be adjusted really high to hop the bbs, and stock hop ups or lower quality hop ups will be less consistant at hight=er setting. really great and scientific videos, subbed! Ya need more subscribers!
I'm a beginner, and I know airsoft guns have recoil for sure, however how does the recoil affect to the whole shooting performance? Would recoil affect the accuracy? ( Love your videos btw way keep up the great work!
The problem is that air has a density about a thousand times less than water. a BBs that crosses 7 cm of water would be equivalent to about 7000 cm of air (70 meters), and without counting the energy lost when crossing the first foam barrier.
Can you make a video on gbbr's adresing performance, consistancy, range, comparing green gas, co2 in capsule and co2 (devil hunter mod) etc? Also an episode on Joul would be appriciated and inner barrels and buckings :D
that did look really cool the water test, and it's been 4 years now. but maybe using the temperature control box to make it a controlled wind box? and see how that effects a BB like you did with the water test. wind in as box might flow a bit odd. but it will be same for every test i would image giving you some data.
now that I think of it's a lot simpler to have a fan or a view of them in a row next to the target at the long accuracy test range you have now a days. and see how different bb weights are effect of wind speeds.
Awesome video. I've seen enough firearms shot at water to know that there was no way the bbs would made it through the "interruption test". The first box would probably stop some actual bullets. But hey, at least it clearly shows shows how heavier bbs *retain more energy* . So it's a successful test, just not testing what you were aiming for. I'd suggest simply shooting in an indoor range with a small fan generating a side breeze, that should test how different bb weights deal with the environmental issues.
Man buddy thanks for the love man and really sorry for the late reply, we missed it somehow. Would be a lot of fun to work with different people around the world!
I’m sure you know this but water isn’t probably the best to use for resistance in airsoft considering water catches real bullets with just like a foot width of water so it’s definitely gonna stop airsoft bbs but still your videos are so awesome and informative I can’t stop watching them great job!!
wow bro.. very very good airsoft contents u got here.. this is what i like to see.. experiments and factual results.. not some BS marketing like other airsoft youtubers.. btw.. try to test .40 gram bbs for that water test.. if it penetrates the 2nd paper.. its less effected..
Thanks for the support buddy~ much appreciated! We got soooooo much more fun test coming~ help us to share our video, the more people like it the bigger tests we can do!
The BB Ballet in the interruption chamber was mesmerizing. Definitely award winning cinema. I was right with you for the ride and then, no conclusion. So, I'm thinking my BBs are usually interrupted by bodies. I'd be interested in knowing: At what distance for a given FPS does a BB impact an object with enough force to affect that object. "Call your hits!" "Did you hit me?"
Dude you are on the right page man! We got this idea written down and latter we will film it with some better slow motion cameras to see different effects with different FPS!
You can get Joule calculations based on BB flight distance. I use a free app from the Google Play store for this. Unfortunately, factors such as apparel and body armor, friendly fire and ricochet rules, adrenaline, and more will have an affect on the "real-world" results. With field limits often based on the Ballahack studies, there's not much we can do to ensure safety while simultaneously ensuring targets feel and call their hits. Unless we start regulating how thick your clothing can be and taking some of the fun out of the game, it seems like a rabbit hole to me.
Shooting that fast is somewhat inaccurate and can cause battery dips.. And was the hop-up adjusted per weight? Also accuracy in correlation with range is the real benchmark if 0.4 is able to perform well on 30 meters and beyond and the others are not, the answer would be ez 'yes heavy BB for the win'.. Did you use 11.1v lipo? And we would like to see the chrono before every test.. Last but not least, It would be even better if each bb weight was shot with the exact same joule - obviously.. I expected a bit better from 4UAD on this somewhat big airsoft topic.. Cheers..
Damn bro!!!!!! This is some good idea man!!! and we got that water port hole on top where we can stick a vaccum cleaner there! LOVE THE IDEA! LOVE! LOVE! LOVE!
The trouble with using the same box is the airflow will be effected by your shape and surfaces, thus not giving a uniform result. If there is not sufficient flow of outside air to equalize pressure, you'll end up lowering the air density and thus getting the opposite results from shooting through a medium. This is why so many physics studies try to get conducted in orbit to minimize the effects of gravity and achieve a vacuum.
Make a box with the right side missing. Use the right side to increase the airflow at 90 degrees to the bb's trajectory and parallel to the ground. Only make the box as long as the width of the airflow is. Do not make it too big because you want the BB to be under constant pressure through the box. You can use a fan or a hairdryer but again a hairdryer will be harder to use since it has a small surface area. A fan will be better because it provides a longer airflow which is not uniform. In real life throughout a BB's flight path through woodland or open space, it will experience different directions of airflow so it is realistic to do the experiment with a fan. It would be good if you then placed the fan so it was pouring the air from above and then from below. My guess is that when pouring the air from above the BB will travel up.
I have always preferred .32 vs .28 on a 1.5j setup(rhop though), I thought the heavier the better, but on your testings .28 performed better than .32s, is there a reason why or it could be that .28s got lucky on the tests?
Paulo Zaak ya this part wonders is too, we thought 0.32 would have a better result. We think it could relate to the design of the hop up rubber. But guess that is something to mythbust!
@@4UADSmartAirsoft Common wisdom that heavier BBs would require a hop rubber of higher hardness rating to achieve a consistent trajectory, the recommendation for 0.28g is only applicable to whatever hardness of hop rubber that was utilized in your 552. To further compound testing of heavier BBs, you need a bolt-action that shoots a much higher velocity to achieve said consistency. There's a reason why heavy BBs are usually marked for sniper usage only as your average AEG / GBBR simply could not utilize the heaviest BBs.
@@nicktam2811 Well, weird how i use a 50° degree maple leaf MR hop that hops 0.4s approximately 100 meters. i was worried that 50° will not make good contact because of high fps, but no! When hopup is on 50% hop, it totally hops the 0.4s to the moon, with 350 fps, so I think the contact pad has alot to say
So based on your experiments... What BB weights do you consider optimal for Indoor and Outdoor airsoft? It looks like .25g for indoor for sure.. Fast moving projectile and really nice group.
Ya usually for indoor games based on the test 0.25 is really ideal and if your engaging distance is less than 20m you can use 0.2 as well. I personally run a 0.2 since it doesn’t hurt as much lol
The density of the water correlates with the weight of water above the impact point. Therefore, you will get different trajectories based upon vertical dispersion of the BB holes. To minimize this effect, you could make the box as short as possible, but will have to consider the magnus effect in your height. To minimize the magnus effect and really study the way a medium effects flight path, you should turn your hop-up all the way off. Also, shooting from a closer distance (such as 2 meters instead of 5 m) can have a noticeable effect on retained momentum. Please read about Archimedes’ Principle for more information. Great work! Much appreciated!
Massive density shift from air to water man, it'll dump all of its energy quickly even if the water section is thinner 🤔 they use water traps for stopping live rounds without damaging them for forensic tests.
I really like the ics sig.... I actually love all ics guns. It's my favorite go to airsoft company. I now own around 25 different ics models. Mostly pistols...
@@4UADSmartAirsoft that would be nice. Maybe you can put in a good word for me about a gun I've designed. It would be in the MARS series. I've drawn it out and designed it already. I've emailed them a few times to see if they would be interested in making it a reality. It's the ICS CXP MARS ANOMALY (LMG) 🤫😎😳😳😳
Excellent work! Very high-quality airsoft experimentation and video. Sub'd! How many reps of the BB weight grouping test did you do? If you made an average of 10 groups, per BB weight you'd have a cleaner result.
MoondogIndustries Each weights of BBs did 1 time, cause we wanna know the actual stock gun performance. If it's any malfunction, well also reveal on our test result :)
@@4UADSmartAirsoft Since you already had the camera, target-stand, and gun set up, it would relatively easy to just run the same experiment 2-3 more times per weight to get an average. You wouldn't even need to film all test runs, just a still frame of the end average. Certainly easier than building a water tank. Great job on building that BTW, even if that ended up being a rabbit hole of unexpected outcomes. I'm actually in the process of repeating a 22lr accuracy test I just filmed last week. After I reviewed my footage I realized I should have randomized the order of which brand was shot within the test runs, so as to average variance in barrel warming and fouling as the experiment progressed. Back to the range next week for another try.
@@Moondog2A Sweet stuff man, and thanks for the suggestions, we will look into that for sure! and good luck with the 22lr test! looking forward to the result!
That was a good video. Most of the time other people I've watched kind of suck but you guys did a great video there. With the math and scientific results.
You should also consider manufacturing and selling a target set... like make the target holders, and targets , with the mounts and everything... I would pay 100 to 150 dollars for a pack of those black paper targets and the target stand...
This would be very difficult to keep variables out of the equation. It would also be incredibly difficult to keep shots in the same POI, which would be crucial due to the somewhat cylindrical shape of a steady flow from a hose.
Good effort, but it is not clear what the results of the interruption test would actually inform. It is important to formulate the research question precisely first and then design the experiment accordingly. In other words, when you have a very clear idea of what you want to find out, you would be much better able to figure out HOW to get the answer. Keep up the good work.
Instead of water, why not try multi layers of 2mm foam board. Use the 30mm total distance with 10 pcs of 2mm board. this will give a small gap between each board.
Great video again lads, very polished and a pleasure to watch - probably good for teaching physics in schools also. Just wondering if you guys are likely to do any gbbr stuff - I have a TM MWS and I reckon you could come up with some great little experiments with that as some lads are reporting 80 - 100m on dmr setups airsoft-forums.uk/topic/40967-the-tm-mws-thread/ Cheers Cheers
You should set up a fan and shoot at a target beyond the fans breeze. Aim directly at a target and measure each weights avg deviation from the point of aim.
Hello very insteresting subjects with scientist approch. I Love. I think you should make your final test with the first size of the box but with fan , Hot, cold and humidity. Very thanks for you job
Nah, based on this you can't draw the conclusion that 0.28 is the best, you'd have to repeat the test several times. And even if the results would be consistent, they'd be only true for this specific power level with this specific hopup setup and with this specific brand of BB. Interestingly, the last bottle of BB I bought was a 0.3 ASG Devil, in my upgraded LCT G3 it produces DMR level accuracy, in other guns it's just meh. Too many factors to just state that one type of BB is the best.
I have to agree there are way too many factors, the result is based on the current environment we tested, and the result can change instantly if anything changes. So I would say we found out 0.28 was the best under our test standard. As mentioned there are way too many factors, we can only lower the factors as much as possible. Still thanks for the in put man!
Matt Mills I wish I can share photos here lol but yes we did try out Homemade jelly in which we used jelly candle. It was really beautiful and yet a real pain in the ass. We thought about using it for our video long term, but the reuseability killed it. But for the sake of the effort will make a video for that!
you guys are like the bill nye of airsoft. great controlled experiments. shows that you guys are quite educated too. far cry from the reddit peanut gallery. hard to get a complete controlled environment with the lower energies of airsoft, but perhaps multiple paper or cardboard screens after the initial 2-3mm barrier would provide very controlled and repeatable interruptions. and you can see how at each stage the diff bbs react.
Thanks for the advice buddy and also thanks for the support, ya for that interruption test we are still thinking what might be the best way to solve the environment control problems, we will try your idea out thanks!
My mtw shoots 50-70 meeters easy.. 20m seems a bit to short to test... But w/e Also depends your jule rules I guess. I mean AEG/HPA is 1,7J Jules in Dk and snipers are 4-6 Jules.. most pistols also have a range of 40-50meters. But very nice video!
I think for this level of accuracy testing, your AEG might reach 70m but at that range the shots will be all over the place. With heavy BBs you're talking about like 2 seconds of travel, so much air interference along the way
Thanks buddy, ya like my SRS a1 can reach up to 80 meters because in the future we want to actually compare pistol accuracy and rifle accuracy, this way we would know how much of a difference in between a pistol and a rifle~
@@Mondochiwan the air interference with heavier bbs is minimal for every gram you go up even tho the velocity is lower. Also heavier bbs allow for longer ranges with accuracy because your applying more hop up
Yep we were scared to shit…. When people shows up we pack our shit and hide. note this was our company’s manager car parking area, at least not as many people would show up during weekends….. thanks for noticing though.
this test is flawed, measuring in squares is wrong because 2 diagonal shots are way off 2 vertical or horizontal shots, the shooting standard is measure the distance between the 2 fartheresg shots
