Thanks for the heads up on future vids

It is not the pressure that causes the drop in power in a regulated gun as the reg pressure remains the same, it is a drop in the volume of air when released. Just being a Nerd.😜😜😜

Next test on a springer.

A little more than a 2 MOA drop at (was it 20 meters?). The first one went high because the air in the regulator/metering system was still warm. I didn't hear you clear the first shot. The gun itself being cold on the night would also have had an effect, so It's a shame you didn't leave the entire rifle outside to cool down. I'm thinking the reason is the same as the reason for the speed of sound in air being higher at higher temperatures. Heat is energy so higher temperatures result in higher velocities. It's counter intuitive because cold air being denser, you'd think it would result in higher velocity for both but it does not. I'd like to see it replicated with other designs of PCP to confirm that it's not something specific with the mechanics however. Maybe something like a Gamo Coyote which uses a balanced cylinder system rather than a conventional regulator. (It's an excellent engineering solution which is not inferior to a regulator, just different) The more you learn...

Good Demonstration... Cold air is denser and heavier, that is why Ballistic Calculators, and some Scopes have a place for Temperature, to compensate for it. Then there is Humidity, Humid(Damp) Air is denser, again why Ballistic Calculators, and some Scopes have a place for Humidity, to compensate for it.

barrel at room temp on first set. barrel cooler on second set, due to being outside? pellets at room temp on first one? pellets colder due to being outside on second one? Different cylinder type used on second set(rat works aluminum, what is HW orginal made of?) Like george also says below maybe try with a chrono, cold air is going to increase pellet drop over range due to thermal current, when its warmer the warm air rises so must how ever small decrease drop. There seems to be a lot more things that could effect the drop.

Just subbed mate, cool channel. Thinking of grabbing a HW30 or 99 for target and plinking fun. Does air temp affect springers?

It would be better to leave the full rifle with the same cylinder ...do your room temp group and then get the full rifle down to the outdoor temp and use a thermometer direct on the cylinder...would be even better if you could get the outdoor temp a bit lower that 3

Should have left the whole rifle outside as the barrel would need to be cold as well as this would of also made a difference

👍

Maybe a good idea to do this test with a chronograph to see if it makes any difference in the speed of the pellet I’ll imagine so if the pallet is falling lower in the colder conditions

BTW, the opposite happens with springers.

I was aware that this happens, especially on a long walk around outdoors in the cold, but never seen it so well illustrated. Nice one.

Magpie in the background noise 😂

I am guessing that the first shot from the cold cylinder was not as low as the rest because the reg had already replenished itself from the warm cylinder before yo fitted the cold cylinder ?

I’ve similarly known PCPs increase in power in a hot sunny summers day, by up to 2 ft/lbs when set up on a cold day , reg/hammer spring etc . Not many folks realise this.

Loving the channel ❤ Down to earth and straight to the point! I’m in the process of pricing up a Weihrauch HW99S in .22. I really enjoy back garden target shooting with springers, but my old Cometa 220 has seen better days. Cheers 👍

Great video that explains some strange fluctuations with the air pressure in my Lyra recently. I thought it was leaking air, but on some occasions I'd check it to find that the pressure had climbed rather than dropped. Cheers 👍

Myself and some club members understood that the cold and heat affects the pressure in pcp's so we waited until the summer around 27'o celcius left the rifles for an hour or so in direct sunlight.Oh boy be very careful every single one of them tested on the chrono in that heat was over 12 ftlb and i mean way over the legal uk limit,so in a nutshell a 11.5 ftlb shooting .177cal 10.34 grain pellets in winter is fine,but in summer time you could end up in deep trouble if caught.Keep up the good work.

That makes a lot of sense now. I took my hw100 out shooting in the cold the other day and it was shooting low. And got lower and lower the longer I was out. I will do some more testing now and see what results I get. Cheers for that my friend 👍🏕🔥🇬🇧

Great video buddy 👍 One of the reasons i shoot HW springers. Cheers!

Your splash point works but there isnt no hold over or under mark coming up on cross hairs have you turned your ballistic calculator on

Cold and clear pellets fly faster...

Where did you get the green bag from . And what's it called please I would love one

Brother, dont dispair believe it or not most shooters are still interested in viewing your adventures, because we relate to your experiences, weve all been there mate. I run an Alpex 4k lrf. on the AGT Vixen off of a Bog Deathgrip. Last month i got set up , checked zero, to find the poa wasnt match the poi. so 2 mags later i found the poi started to match the poa. Then half an hour later im stood in a hedge freezing my ging gangs off, I lock onto a rabbit. 32 yards side profile , easy shot . So i bring the poa up to the rabbits sweet spot. squeeze the trigger, and put a hole through the tips of each ear. These things happen to us all. this is a great video, well commented on and explained. next video please . shust wait till the cold front passes. stay safe Brother. You wil get where your wanting to be, just dont be down on yourself while getting there. PMA, all the way .ok.

Brother its real, poi shift is a pain. ive stopped shooting just now, due to the cold. exactly as its happening here with your gun, happened to myself a month ago. its good for those not aware of temps having an effect on there guns, to see it. The temp effects the weight of the air in the bottle, so it tends to give a 2inch drop at 40 yards, just under an inch at 30 yards.Beyond 50 you can only hope you hit the target. The Hw 100s are very prone to poi shifr as are the BSAs. You could try keeping the gun warm before use . but it quickly cools down. That said if you keep putting rounds through the barrel the gun will warm up, the poi will improve. Though that no good if your stalking for a few minutes, because again the gun gets cold.

The brutal truth behind rifles and hunting. No need to have "fake" successful shots for click baits and medals like too many do for various things these days. People are too afraid to speak the truth and be raw. If you can't be raw nothing is authentic. Good video 🇬🇧

Great video. Agreed the point of impact does drop for pcp’s with extreme temperature drop, as for the content of this video it shows the true reality of what happens when things dont go to plan, I personally prefer watching content like this, thats genuine over stuff that scripted & edited to look text book.. i usually switch off videos with digital scopes & range finders especially with those showing pre determined aim points, my personal opinion is the industry is dumbing down shooters ability to learn things for themselves without cost/convenience of technology, dont get me wrong technology is a great tool to be used but its sad to see most influencers starting to rely on them making people feel its the only way to get results. Keep the videos coming :)

I'm getting my m4 back from the gun shop in a few weeks. Would you like my m3 it's got a leak to fix but your welcome

Really enjoyed the video my friend 😊👍❤️🇬🇧

Taking the fat off with a fish slice ..... like DUH

Hi, nice review, I’ve had one of these for a few years, I use it to rid my garden of grey squirrels from short distances, 8-10 yards. Is there any loss in power with the silencer you demonstrate? Many thanks.

Dam youre the man when it comes to cheffing it up,im not so great at the old cooking game,i just didnt learn regretfully,maybe i can learn a thing or two from you,i would absolutely dog down that gammon,gammon and chips is legendary and i havent had it in far too long that cola infused gammon looks like it would be outstanding!!! Also what a magnificent beast your dog is,he is truly stunning..

Yet again fantastic video.

It's the second of third time I've watched your video and I actually bought one of these rifles for my youngest son for his birthday . Because it reminds me of my Old Webley Beeman Excel that I still own from back in the 90s , and still in very good condition and still working well . I like this Webley VMX O S so much that I am going to buy another one very shortly for my daughter and her boyfriend . Nice backyard shooting man . Barry . North East of England . 🏍️ .

The videos are all the best ones I think I have ever watched. Keep it up. You're doing good

Considering circumstances for Christmas time this year for you all, it's nice to see the family making the most of the Christmas time because Outdoors Britain Mother in law loved it all so much. Outdoors Britain dog is waiting for anything to drop onto the floor, his first Christmas time too. He has the kindest eyes! Will have to do a starter involving some of what you caught at golf course one time?

Excellent video mr and mrs outdoors Britain

How much for. The scope mate?

You are a good man,she was a unique soul,and she most definitely was your biggest supporter,loving your content its been great watching your vids man keep up the great work looking forward to the sea fishing!!!

Yes!!outdoors Britain 🇬🇧 all sounds great to me. Looking forward to it

Sorry buddy 😞

Thx for the update looking forward to to seeing future content

Sorry for your loss. Keep up with you passions in life, look forward to seeing some carp fishing on top of the bunny cull!

R I P Earth Warrior, condolences to your lass and you.

Great vids man!!!

Looks great,,,will try it

So pleased that you secured the golf course permission again!! Well done!! I miss your little frenchie waiting for her treats. U mentioned in the past u had another dog also, I can’t remember what its breed was, my question is tho do they also like the raw treats, like the ears etc, also do u give your dog the carcasses from what you catch? Sorry to ask might sound a silly question but im interested in raw feeding too.❤

Mr outdoor Britain, is there anyway you could do a video on the IMPORTANCE of a good clean ETHICAL shot, not just aiming at a bunny and taking a shot with not killing it out right. Hope u dont mind me requesting to do this❤ps LO❤VE ur cruset oven pot!!!

I appreciate the fact that you also let us appreciate the beauty of the wildlife you come across on your hunts. Thank you for that!!❤
