Are JSB heavies really better in the wind? lets find out..

comparing the 3 most common air rifle pellet weights side by side in light winds.
the pellets on test are the 7.87gn jsb exact express
the 8.44 jsb exact diablo
and the jsb heavy at 10.34gn
as per usual its hard to perform any scientific testing outdoors but the results back up the ballistic calculators results..kind of
the rifle is an Anschutz 9015 in sub12 and the scope is a prs specific discovery ed prs 5-25x56
hopefully in the coming weeks i can test the new h&n 8s side by side a good batch of the jsb exact..

[@nickholmes6376]

Discovered your channel a couple of weeks ago, i really like your enthusiasm and energy, the info is solid and presented really well, i like your no BS approach and you cram loads of useful tips and thoughts while shooting, also just made a silent pellet trap from plumbers putty for at home pistol shooting 👍

[@tillysgunstocks]

Awesome stuff mate. Thanks for being a part of the channel 😉 There's loads of cool stuff planned for the coming year,if the weather ever gives me a break...

[@stephencope7178]

A number of shooters bulk buy, once a good batch number is discovered. Ten sleeves of ten tins is not unusual.

[@AirgunJohnny]

Great shooting! Thank you for preforming these tests to help get us on target in the 🌬

[@xWILZTAx]

I find my hft500 likes the heavies over all others at all distances. Managing 0.6cm 10 shot groups at 50m outdoor, unweighed and unsized. Exceptional pellets.

[@stephenlambert9826]

Do you find their performance varies from batch to batch?

[@xWILZTAx]

@@stephenlambert9826 not sure, as i buy same batch in 10 tins at a time. I have noticed the hole in the bottom differs in depth and width from batch to batch though. 🙈😂

JSB Heavy 10.34gr are my favourite pellet, always consistent through every gun I have tried them in.

Nice, same results I've gotten out of my TX200 MKIII, thanks for doing these tests!

[@Happy-Me.]

If you compete what pellet does your TX prefer as Springers are supposed bto favour the lighter pellet.

[@rickoszpar9513]

I use the 10.34"s for most of my shooting through my Kral puncher jumbo. They are much better all around. But I use the 8.4 for shooting pests indoors at a reduced speeds to prevent property damage if they pass through. But I shoot hunter field target with the 10.34 and get great performance down range. They are not as affected by winds as compared to the others.

[@jameshoward9700]

Nice! I think the wind might have varied? I think it's very rare in the UK to get consistent wind speeds. Even a slight speed fluctuation is huge in %age terms. And then there's gusts... direction shifts... a mare. To counter this, I test pellets in rotation: A,B,C,D; A, B, C, D rather than series: AAAAA, BBBBB, CCCC etc. Messes with your drop a bit, but with enough height in the target, you can accommodate. This does even out the groups. As for heavy vs light I think in very slight wind shifts heavy pellets buffer the variable, but if it's 'windy' they all drift a mile! As such I do like the mid-heavy pellets (9.5g ish) like QYS heavy and H&N BFT, if they work in your barrel. But barrel preference trumps weight, so I often shoot JSB Exacts too (Weihrauchs). With my FX magazines (toot), I agree, QYS streamlines work excellently. Apart from the first two from the mag. Who needs the first two (only 10%) anyway...? May have to get a single shot gun this year..!

[@laurieharper1526]

Interesting results and nice shooting. I like heavies in my sub 12 springers. They seem to retain a bit more energy. At my club range, some of the knock down targets are a bit stiff. Ordinary Exacts won't always work on them - they wobble when hit but don't go over - but heavies do the job every time.

[@Woodgate425]

Excellent stuff and very interesting as always. I must say I’m not a fan of the lighter pellets even at closer ranges. Keep up the good work Tilly and looking forward to the next instalment 👍

[@tillysgunstocks]

I've just had a few new pellets delivered mate.hopefully over the Easter break I can get out in some calm conditions. I thought these new ones might be comedy pellets but they actually look far better than I thought,and it'll be a good chance to bring a very unusual barrel onto the channel..

[@ezi0n]

I shot the heavies at 80yards lately outside just bipod and shoulder no rest and they grouped pretty well on my sub12

[@Happy-Me.]

I love the Express pellets in my TX200 but found out that in HFT competition they were running out of energy and then being blown off target.

[@markhomer5704]

Yet another interesting vid .. always found the 10.34's a good pellet in most rifles , maybe not so good as the QYS 13's , but not much in it ..

[@tillysgunstocks]

Them qys magnums were the best of the real heavyweights I've used.but they really didn't run nicely through the 9015. The sight picture was really jumpy and the power issues 😬 Accurate though!

[@essexhognose1808]

They were very accurate in the Brocock Sniper but well over 13ft/lbs! Shame as they shot very tight and consistent when tested

[@darrenm7964]

Thanks for another interesting video, I've always used 15.89 .22 jsb jumbo exact in my hw110 thought I'd try the 13.43 jumbo Rs,wow what a difference a lot flatter trajectory,faster , better consestincey still good in the wind upto about 40 yards haven't tried at the range yet but on my permission great should of tried the lighter pellets earlier,if I get a chance at the weekend I'm going to try the jsb express 14.35 thanks again also got some timber and lead flashing to try and make your pellet catcher

[@tillysgunstocks]

[@michaelholt7963]

Yeah they basically turn your 22 rifle to a .20

[@mrln247]

You did put in some windage adjustment when switching to the heavies which may account for group position.

[@SoutheastShooter]

Great info, interesting results👍👍👍

[@garynasrallah8710]

I have a BroCock concept. And I shoot the 10.65 4.50 head size and they're very accurate. And then in my day state Huntsman 177 I shoot the FX 10.34 and they're very accurate. I try to stay with the heavier pellets also.

[@vansantsam]

With no adjustments the heavier pellets should drift about the same or slightly less as the lighter ones, because they are in flight longer. If you increase the hammer to increase the velocity and if the velocity is the same for all 3, then the heavier pellets will drift and drop less because of more momentum and shorter in flight time (they will slow down less, muzzle to target will be less time)..

[@Happy-Me.]

This is interesting as in HFT competition the majority of competitors use 8.44 grain for a flatter trajectory than the heavies and heavier than the express pellets which run out of energy..

[@jasonyates9552]

You want to try hn field target trophy hornet iv only just started using them and they are very impressive iv got them up to 35 yard's over that I'm not sure but we'll worth a try buddy

[@gigagiga4172]

thanks bro!!! plz what a target paper? can you atached?

[@yellowyoutube244]

Nice & interesting video .. 👍 My Avenger's barrel loves QYS 9,5 and Rifle field super magnum 10.0 better than JSB Heavy and they all drifted about the same in the wind. And since Rifle fsm is considerably cheaper, it's my goto pellet. I use my avenger for hunting (squirrel & birds) shooting; at around 880-890 fps, I got similar groups like yours at 20m but larger group than yours at 50m .. maybe I should turn-down the speed a bit to get better pellet stability.

[@williamczupryn2642]

What do you think of Minnelli stocks.

[@Judge_Dredd]

I won't consider anything above 4 mph as viable for target shooting pellets, so I'm impressed with your 9015.

[@tillysgunstocks]

I shot it a few weeks ago in that big storm Had side winds of about 50mph. The footage is bad on account of the wind noise and everything getting blown over but I'll get it into something of a video soon. Was a pretty sketchy experience tbh

[@paultowns9880]

Great video.. Im looking forward to you testing the H&N 8. Keep up the good work!

[@tillysgunstocks]

I missed the initial batches of the 8's annoyingly but have some on order to test in the 9015s barrels and the xti

[@beardmeetsworld0707]

I've shot Heavies for years now and I hear this all the time. The reality is, yes the Heavies are 20% heavier but they're also going c15% slower, so are exposed to the wind for longer. An argument that will run and run...

[@tillysgunstocks]

It's not really an argument though, the heavies are ballistically better down range. Take your 55yard targets, a 5mph crosswind you should see a full inch less drift with the heavy over an 8.4 The time of flight difference is 0.01 seconds longer with the heavy. With your rangefinding ability I can't see why you'd use anything other than heavies (well assuming you get a decent batch of course) Nice vids btw 😉

[@beardmeetsworld0707]

@tillysgunstocks ☺️ thanks. FT is prob split 70/30 in favour of using 8.4s but maybe thats just through inertia? 🤷🏻‍♂️

[@tillysgunstocks]

I do believe there's alot less dies of heavies compared the 8.4s and variants so it'll make finding a perfect batch of heavies a bit of a chore compared the exacts/fields. Don't know, but it's all good fun trying this stuff out though. I'm looking forward to running all the batches again through the xti, I'll be interesting directly comparing to the anni barrels. I'll probably transplant the cz Into the xti see how it performs on a fresh action

[@robrobertson1586]

With a HFT 500, shooting 25 yard BR, my go to is JSB 4.52 sized and lubed. When the wind is really bad. Ie over 8 mph, I go to 4.52 heavies. Why? Because I don't need to have a aim point so far out from target. 😊. Better to have a aim point on ring 5 rather than the next target over, as an example

[@Chris-vc1dh]

springer more powerful than PCP you think?

[@African-Budget-Pellet-Gunner]

​​@Tillys Gunstocks when you change over to the heavier pellets and you got a shift up on your POI, why is this?

[@tillysgunstocks]

Not sure on these ones. I didn't notice anything out of the ordinary when shooting them, the batch of 8.4s i shot before wasn't great so they may have been dropping a little more. I'll dig out the cards when I get chance and have a nose. Probably be better to look at the drops between the express and the heavies to get a definitive answer. Also sometimes you just get an unexplainable weirdness between weights. Often get it between the same weights, from different dies too. There's also the potential the (apparent ) peak of the trajectories is at slightly different ranges so looking like more or less drop. I'll have a better nose when I'm back filming and have the cards to hand.

[@African-Budget-Pellet-Gunner]

@@tillysgunstocks Thanks I was assuming the 2nd part of your explanation, that the shot curve of slower pellet(heavier pellet) peaked earlier so your zero actually moves towards you. Thanks for the reply I look forward to your nose.

[@eck2go]

would have been nice to mention what holdover (mill dots) would be recommended; this may sound stupid but I am a novice.

[@tillysgunstocks]

Hi Eric, the holdover that I get with my setup could be vastly different to yours. The scope height,power/speed, and magnification of the scope will all show an apparent different holdover. The main thing to look at is the drop between the different weight of pellets. Just so you can visualise what's going on and that the holdover amounts arent a huge amount greater for a heavier pellet,compared a lighter one. We can Learn to range the distance to our targets pretty well with practice, but reading the wind will always be a dark art and much more of an educated guess. I'd rather reduce the work I have to do judging the wind 😉 In a few of my other videos I will often quote the drop from my 25yd zero, it's very interesting

[@BarnyDaddy]

I use 4.52mm 8.64 grain in my TX for HFT

[@ajb-64]

Thanks - very informative. Do you happen to know the velocity these pellets are running at in the rifle?

[@tillysgunstocks]

Yep sure do, express 800fps, exacts8.4 ,777-780fps and the heavies run 710 ish 😉

[@African-Budget-Pellet-Gunner]

​@@tillysgunstocks when you change over to the heavier pellets and you got a shift up on your POI, why is this? Is it perhaps the Intersection between your shot trajectory and sight line(scope) moved closer towards you due to lower fps. In theory your 1st zero is actually closer to you?

[@Morayfirth1980s]

Really doesn't take much wind to shift any weight of pellets but prefer the jsb 10.34 over most

​@@stephenpearson8720agreed 👍

[@SteHughes90]

I've done similar tests and found the same results. Heavies are heavier (duh) but due to the higher BC than the 8.4's the drop is the same. They also seem to take less wind but there is no perfect way to do test this in the real world.

[@tillysgunstocks]

What we need mate is Brian to rig up a couple of big fans on his indoor range to replicate a consistent wind..that would be great to see I've rapidly gone off the lighter pellets the last few years when the barrel allows,however one of my old hft rigs was set up to run 7.9s(accupels of all things,the old crossman versions) and the same rifle won the nationals and claimed a ton of silverware(not in my hands😆)

Good vid, but I really feel for all you Europeans and their ridiculous "sub 12 FPE regs!" Do they allow you to own and use "sling-shoots" or do they regulate how many rubber bands you can use? Lol

[@tillysgunstocks]

In England the sub12 isn't too bad for close range pest Control and use in smaller spaces. We don't need a licence or anything for sub12. just some sensible storage precautions. We can have some really mad high power air stuff and large calibre powder burners if we want and have a legitimate use for them. Getting a firearms certificate here isn't really a problem. But you wouldn't get a high power fac air rifle to shoot in your garden. But if you have enough space on suitable land or a club membership of a place that has the space it's really no problem atall. I quite like the challenge of sub 12, it makes target shooting really tricky and fun..

[@MW_1981]

We are barely aloud to use cuttlery with our dinner these days!

[@sid35gb]

I have a different position which is weight of pellets are irrelevant. If you can zero a rifle indoors you know how pellets behave in perfect conditions. When shot outside it’s a different ball game altogether no matter what the weight is they all drift they can also strike higher or lower because wind is not consistent. Also the shooting here is only relevant if you shoot only in that field on that day from the prone position. Anywhere else these results are meaningless. To learn how to deal with wind is to shoot a lot in different locations in different weather. This is the challenge.
