Love this experiment. I’ve always known that weather and bullet speed can affect accuracy, but I’ve never seen anyone do this kind of experiment to demonstrate those effects. Nice job 👍
Thanks buddy 🙂 Sometimes you just do things while you shoot without noticing the actual value, and Ive been doing this for ages, so I just occoured that it would make an interesting video for people who pays attention to the details 😃
Really interesting! I think if you keep record of temp/air pressure (or simply density altitude like used in aviation) and plot that against best velocity for smallest groups you could well end up being able to predict what velocity to shoot at on a specific day for best results. As you mentioned air density changes with altitude, temperature but it also changes due to high and low pressure weather systems moving in. The weather systems can make a difference of quite a few millibar. Then there is also humidity that changes air density, the higher the humidity the lower the air density so that should also be taken into account. All really fascinating! Thanks for sharing, you got me thinking!
Great video. It answered a lot of questions that I have been asking my self. puts it in prospective. I also think altitude has a lot to do with it too.More than we think.
Ive heard of velocity shifts up to -/+100fps from altitude differences alone, it’s crazy how much of a difference your location and atmospheric conditions makes, especially for these small calibers. Good video.😊 & grats on having a wife who likes your hobby, mine hates every bit of it.
Actually I believe that my wife sometimes fakes the interest to make me happy 😂😂😂 But makes me sure that she really loves me 😃 Didnt know that altitude could that much of a difference 😳 But it just shows that we should pay attention to this, even at much smaller changes 👍👍
@@VikingAirgunner Yeah it sounds like alot, ive been trying to remember where i read it, Airgun Nation i believe but i can’t find it. As for the wife I can’t relate..atleast mine is a great cook though 👍
Thanks John 🙂 This whole thing about the right velocity is what has been occupying me for a long time, so kind of a personal video. Thats why it is nice to hear that it is relateable anyway 🙂 Have a great weekend 😎
Thanks for the video Peter. i used your tuning tip with the front valve to remove low starter shots on my .25 M3 25.39gr. I checked yesterday from cold and got 905, 902,907. An improvement as I noticed some starter shots were 20fps low before. No good as a hunter. atb neil
Great video again, thank you. One thing I struggle with more than anything is I can tune my M3 perfectly, by following your video guides. However, a day later shot velocity is down and accuracy is off. Not weather related either. Any ideas?
The Impact suffers from o-ring stiction on the valverod due a bad design. It means it takes couple of shots before its back on speed. No blame to TH-camrs, but they all keep this quiet.

@@NickGled I think you should write them and suggest that 😃 Funny thing is that barrels can be different and setup will affect harmonics, so a velocity should always be seen as a guideline 🙂 All that matters is what works and feels good to each person 😎
Hi Peter I got myself a harmonic tuner for my tensioner.its awesome. I tuck the tip about making Mt tensioner solid.mind you I did that a while back...I love it now.lazer beam 😀
SUPER!!! Im very happy to hear that it has such a good effect. And even with the solid tensioned barrel😎 Knowing that it usually takes a while to reach the true potential of a setup it will be exting to see what results you will achive. Please keep me posted buddy 👍😎
Good morning Peter here at my place in CT USA not sure what time it’s is where you live but I have a question for you I haven’t used my m3 in months and yesterday I was putting air in it and my first reg was up to like 225 and my bottle was like at 205 so I’m wondering if I have a stuck reg and what I should do now I know you fix your air guns so I’m hoping that you can help me out thank you Del and hopefully you and your family had a great holiday tu again Peter
@@VikingAirgunner ok I’ll give it a try it won’t be until later on I have 8 snowblowers to fix and a service call to get to question reg gauge or bottle gauge thanks again
Thanks for your video. I have a question after tuning the fix impact m3 and after a couple hours, the velocity goes down and goes back to normal after 10-15 shot, any idea why it happened thanks for your answer
Good question! I have tried this myself and I dont have an exact answer on why this happens. What I usually do - because I know that it will return to normal - I dont try to retune the gun, but as soon as I notice this issue I increase the tension on the hammer spring by one click on the power wheel. Shoot a couple of shots untill I see a higher velocity than the gun was set for, and then I reduce the hammer spring back to where I started. You can try this. It is the best advice I can give you. But I would not be surprised if this issue disappears after a while where you only make minor adjustments to the gun 🙂
I got a bit freaked shooting my Two yesterday, the 13 grain Zans was shooting pretty darn well at 1020 FPS, but yeah the sweet spot is a bit lower. later in the day as clouds and rain got near and so light dropped i changed to 50 M and even disposed of a few beast pellets i had in surplus, at 50 M the 13 gr Zans was just lasers at 972 FPS. Much better than the KO at the same speed / setting Mind you at 86 M they was also fine, i killed 1 fly and i am sure if flies have hair on their ass i removed those on another fly. Also killed a few flies and a small spider at 50 M, and cut countless blades of grass From 10 in the morning and until 7 in the evening i was one big smile,,,,,, yes when i shoot i SHOOT A LOT
That is fantastic news!! Usually it takes a while to find the true potential in a gun, so it seems that your have found a great gun. Very happy for you 😎
@@VikingAirgunner Yes it is nice, ATM playing with the 13 grainers, next outing i will be more serious with the 16 grain Zans 13gr seem to run well from 910 to 1020 FPS. but somewhere in there is the sweet spot, and i think it is not far from the same speed my Maverick like to shoot the same ammo. Going shed building and of course shooting again Tuesday, and will probably again spend 2-3 days at my friends place. Have just ordered sekmet gauge for regulated pressure,,,, and HUMA regulator. And more 2" targets as i seem to have been burned 2 times with targets now. First on aliexpress with targets with no splatter effect, and the replacements i ordered in Finland, well i heard nothing since June 3 when i ordered. So i might have to take the drive back to Randers if Huma and Mundilar have stuff in the mail for me Wednesday. but i gladly do that for shooting hardware. And of course a pitstop on the way at the Kiosk in Bjerringbro for a nice old school ice cream in a cone.
Har det fuldstændigt lige sådan i forhold til dette at anvende singel-loader kontra et magasin... (Der kommer simpelthen mere omtanke og omhu omkring det enkelte skud... 😁). Når magasinet er i kan det godt komme til, at gå lidt for hurtigt engang imellem 🤭
Here in India we are only allowed to use .177 calliber Air guns....so your channel is great source to learn more about my impact m3 .177 calliber....👍
Wow I did not know that, but I guess that we have similar laws then 🙂
Thanks for tuning in buddy 👍😎

What is your setup? Length and type of barrel in particular.
And what ammo are you using? 🤔
The Impact suffers from o-ring stiction on the valverod due a bad design. It means it takes couple of shots before its back on speed. No blame to TH-camrs, but they all keep this quiet.

I imagine that your gauge is on there too tight.
Try to loosen it a bit. That usually helps 🤗

Is it using a heavy 700mm stx barrel or a 600mm master polygon?
Im very happy to by back to the 700 mm heavy liner 🤗
