Fine tuning the most expensive air stripper in existence. Does it actually work?

[@ewanhobbs6297]

UK Neil air stripper on my 9 year old FTP900 set at about 2.5mm gives outstanding tight groups using JSB 8.44's 4.53, nicer to shoot, no sight picture movement at all, before deciding a 'batch' of pellets are not good enough for comps maybe try adjusting the stripper first.

As always... another very interesting video ... thanks for taking the time to share with us ................ 4ndy

A few points to consider: You need to test indoors to exclude the wind. Removing the cone has the air stripper outer tube act to concentrate the blast on the rear of the pellet. Worse than a completely bare muzzle. Changing the position of the cone also affects the barrel vibration characteristics. All of your "air stripper" results could be barrel harmonics changing. Add a test for when the cone is paper thickness away from contacting the muzzle. That shorts out the air stripping function completely, but would have vibration characteristics similar to the shortest setting you tested. To separate harmonic effects from air stripping, you need to find a way to keep the mass x distance of the cone in the same place relative to the muzzle, while only changing the cone lip to muzzle distance. Pellet length drives the distance and timing of pellet exposure to the initial air blast. If the cone is too close to the muzzle, more air follows the pellet down the cone. So a closer cone to muzzle is not necessarily better, except for the start of the air blast; up to a point. That air stripper tube has so much material cut away that the front may be vibrating on the (overly flexible) three remaining "pillars" around the generous windows. If so, moving the cone may alter that vibration to produce tighter or wider grouping. If you set the cone very far forwards you may find another "node" that produces tight groups. If so, the vibration is dominating air flow considerations. If you want to improve air stripping, increase the amount of air that the air stripper has to deal with. You can do that by shooting heavy for caliber pellets at 900 FPS. This assumes you have a FAC.

Correct on all counts mate. I'm working on an indoor space for this sort of testing too. I'm somewhat familiar with how the stripper is working and it's foibles, but going into mad detail in the vids would only really be watchable for us real nerds. I try to keep things simple, not go too deep and keep them enjoyable with a bit of humour. 😉

[@rickoshea8138]

@@tillysgunstocks You are putting in significant effort. The question is how can one make that effort more meaningful, with a better signal to noise ratio? If you are concerned about the viewers getting bored, gloss over how the test has been normalized. As if the only variable is the stripper to muzzle distance, like you are doing now. Rather than me wingeing about your test, I could help by designing a series of 3D printable air strippers, that would have the same mass and mass concentration, with only the cone spacing from the muzzle as a variable. Does your barrel have a 1/2 20 UNF thread on it? How long is the thread? How far from the barrel shoulder to the front of the air cylinder? What is the radial gap between barrel and air cylinder?

[@imdaprophet]

@@rickoshea8138would you sell a set of air strippers if you print them.

[@biketech60]

Always something new to learn . Thank you !

[@TripleGRogerLait]

I have been using strippers for years for HFT and they were ace. I got the new Eaglevision stripper and tuner for my FAC guns and they honestly worked amazingly . Made a big difference and the groups were so so much better. Good video by the way mate 👍👍

[@Happy-Me.]

Would it be an idea to do tests like this in an indoor range?

[@gratefuldude7511]

Great video I’m certainly going to look for one for my Lupo Rosso.

[@messor01]

You should test whether you can shoot tighter groups with the JSB slug, with this air stripper.

[@Happy-Me.]

It's a shame that you didn't give us the size of the groups.

[@Hypercolumn]

Interesting! Could it be that the closer than factory settings work better because you are using shorter pellets? Presumably there will be some relationship between how long the pellet is, and how far from the barrel crown the optimal stripper cone position is..? It would be interesting to see whether longer pellets prefer a longer gap!

[@Biffo1262]

They work without any shadow of a doubt. No matter what I did with one of my rifles the groups would not tighten up. I decided to try an air stripper and difference was amazing.

[@tillysgunstocks]

I'm contemplating fitting the xti one onto the cz barrels in the 9015. It works great and definitely looks cool too...

[@Happy-Me.]

I would definitely want to see a test like this again.

[@markk2403]

i did .own a hastan air stripper. put it on walther terrus. and diana. T 34. . so. looks nice. and . adjustable. loc tite.

[@pasegers]

great video ! but maybe the result can also be dependent with distance ?

[@Happy-Me.]

I've set my Rowan stripper based on the length of the JSB Exact 8.44 pellet. What length are the Exact shorts?🤔

[@DomRivers67]

Commenters don't seem to understand the principle of these, as the pellet rushes down the barrel it displaces air, causing turbulence and "dirty air" in front of the pellet, however, what is worse is the air just behind it, that immediately goes past the emerging pellet exacerbating the issue...an air stripper should be designed to direct the air, via cones and slots, out to the sides Whether this is actually the case isn't the question, whether it makes any difference obviously is.

[@freakygardener8033]

This is the first I have ever heard of an air stripper. I don't get what it is actually supposed to do!?!?!?

[@Raul28153]

I am having a difficult time imagining a tube-in-tube slip fit that doesn't also impart some lateral wobble making for wonky tuning.

[@kris2435]

Thanks for sharing 👍 Is there an adjustable stripper to try on the 9015?

[@Esoxlucius51]

Very interesting video,I think I might wait until I see a rifle dedicated stripper ie one for Daystate huntsman or airarms s510- if it wasn't for you doing these tests I'd never consider buying a stripper,my rifles have to do different things not purely target shooting.I would be Interested in seeing how much (if any) noise reduction compared to a mod & wether its useful for hunting.👍ta matey.

[@brendonbenson]

I'm wondering if that stripper is working the same as tuner Iv not experience using a stripper but put my tuner from rimfire ( EC tuner ) on my HW 100 in 177 and had unbelievable about 6 mm in zero wind for 11 of 14 and about 19 mm in total at 50 m with jsb heavies needless to say I went back to shop and bought a sleeve

[@scinner28]

How many yard's ? i think i overlooked it ..50?75? ore25?

[@tillysgunstocks]

Just a shade under 25 in this one mate. It's the most sheltered spot I have. Also surprised at the variation at what is a relatively short range,ofcourse the deviations are amplified at the further ranges.

[@scinner28]

@@tillysgunstocks nice thx

[@Woodgate425]

Excellent video and really interesting. Who’d have thought that what is such a relatively small adjustment would make a difference. A friend of mine is currently experimenting similar with the barrel weight on his HW77, he is turning it ever so slightly between shots and swears that it makes a difference. Makes me wonder if the same could be true for silencers?

[@intractablemaskvpmGy]

I like. Tuning can accomplish this as well. However, it seems a stripper offers negligible return in accuracy. If you are obsessed with chasing precision then...

[@rasoulhsn3346]

Hi there, You have had 9015 and xti50, which one is more accurate and convenient???

[@tillysgunstocks]

I love them both... The 9015 is built to fit me perfectly and handles amazingly. The xti is currently totally standard apart from some cosmetic tweeks. I think once I get a chassis on the xti it will have a slight edge over the 9015. At the longest ranges the xti is quite a lot better,but at all the usual distances 50m and less there's very little between them accuracy wise 😉

[@Airgunfunrich]

Stupid question. What are JSB shorts?

[@tillysgunstocks]

They're a variant of the exact range. As the name suggests they are shorter . They aren't regularly imported Into the UK though☹️

[@Airgunfunrich]

@@tillysgunstocks cheers for that explains why when I’ve searched for them nothing comes up any idea where I can get them?

[@sean19]

​@@tillysgunstockscould you let me know / recommend a air stripper for my fx dynamic takedown. Not bothered what one and obviously won't blame you if it's shite for my gun 😂. Thanks in advance. Sean

[@tillysgunstocks]

How does it attach mate? 1/2unf?

[@xsamitt]

use a rear bag for the stock not on your hand... your pluse will affect the groups. pointless to check for accuracy with out a rear bag.. just trying to help....... and as well u need to do this kind of testing on a windless day with wind flags set up to let you know when the wind is truly out out the equation

[@MrRockstar1968]

Shame there ain't a 25 yard indoor range near where you live.

[@tillysgunstocks]

There is mate 😉 I'm nearly finished on my probation period too.. 25yd Indoors and 50m outdoor fac rated too. Will be a great place to really get to test stuff properly and build some mad high power stuff as well.

Do are strippers work? If you toss a penny into Lake Michigan does the water rise? Yes it does. But……….

The bloke who bangs the drum seems to nod off from time to time!. Could do without the daft sound effects.

Sounds like his crack hit is wearing off. It’s all in his head. Or the old bill banging on his door

[@CsakEn-pl7uv]

To me it seems more like when you fit it it makes it a lot worse then you adjust it to minimise the adverse effect you created by this gimmick 😆
