Does Co2 lose velocity in cold weather??
 

if so, how much, as i was going to buy a co2 gun to use in 10 to -10 degrees celsius.

I did for 20 minuites, and i could find that yes, it does but not how much. the gun is 350 fps, and i was wondering what it would be in these temperatures. please, do not comment if you are gong to hate.

Well it definitely wouldn't go up. I imagine it would be similar or at the very least stay in the ball park area of 350ish. Although cool down effects make last a little longer given the cooler temperature.

thanks, i read somewhere that it would severely drop, but I think that was for red/green gas.

I was also wondering a few things regarding fps. i have been shot with a gun that shoots 350 fps with .12 grams, and i was wondering if a gun that shoots 350 with .20s would hurt much more. Also I was wondering what a first good primary (around 200$, just for 1 on 1 or 2 on 2 with close friends) would be (that shoots under 350 fps). thanks

oh, and sorry if im causing trouble... but how much fps would a green gas gun lose in 10 to -10 degrees celsius??

at 10C (50F) you follow an isotherm at about 650psi (horizontal line labeled 50F where you get liquid-gas saturation). At -10C (14F) you get an isotherm at 400psi. 38% pressure drop across the temperatures you specified. Unless you're shooting from a regulated supply of CO2, you're going to see significant performance variation across your specified temp range.

Don't even bother with propane.

Swing from 78psi to 38psi. The higher pressure is already borderline acceptable (about the same as HFC134a at 20C).

I'm not terribly knowledgeable about gas guns so I am going to answer this question from an electric gun perspective.

A heavier BB will degrease the FPS.

So a gun that shoots 350FPS with a 0.12b BB would create 0.68 joules of impact energy. The same gun loaded with 0.2g BBs would fire at 272FPS and generate 0.68 joules of energy.

actually you know what, I honestly dont feel like going into extreme depth since its late and Im tired and in my pajamas and I missed watching house and how I met your mother tonight so Im cranky.

The long and the short of it is yes, it will probly hurt more. Pain is experienced differently by everyone.

Well there are a lot of variables.
First, you need the exact temperature. Then humidity. Then how many shots your taking, as the fps will go down consecutively after each shot. Then math it all, and you'll have your answer :D

But seriously, most things that run off propane don't work for more than 3 or 4 shots below 0 degrees. They're optimal temperature range is above 20 degrees.

CO2 will have more power at the same temperature as propane, specifically because it's a more powerful and stable gas. However it suffers from the same cooldown effects. You still won't get more than a few rounds off before the valves freeze open.


T7, I'll add on to your point;
It depends on the gun. GBB pistols work like AEG's for the most part where differing weights of ammo have the same energy. However in gas rifles with longer barrels, heavier ammo typically has more energy. For example my PDW shoots 380fps on .20g BBs, but on .28g BBs is shoots the equivalent of 405fps on .20g.
But it still doesn't work worth a damn at 0 degrees :D

OK, thank you, but tokyo seven, i realized it would carry the same power, i was asking about a seperate gun, because i have been shot with a gun chronoed at 350 with .12s, i was looking at a new gun chronoed at 350 with .20s, wondering how much more powerful this is. also, can you think of a good compact primary under 200, and under 350fps. i dont really care if its clearsoft, its just for messing around with friends

So firing up the barbecue during winter is out.

From what I remember shooting CO2 airguns in cold weather (0*C to -30*C) there is a performance drop and you get significantly less shots.

A gun that shoots 350 on .20 shoots with .453j more force.
350fps on .12 is the equivalent of 275fps on .20
I don't think your going to find a good primary under 200fps. That's just silly. If you can't take the pain, don't buy the gun lol
marui guns are fantastic, and most of them shoot 280fps

No sorry I cannot. My job is to assist with the adjustment and education of new comers. I specialize in airsoft items from mid range to high quality and providing answers in the most basic format to those for easy understanding. While I am familiar with low end quality products my hands on experience is in the range zero to nill. If you are interested in low end soft air products I suggest you try walmart, Canadian tire or perhaps the dollar store.

So mass = zoom

I understand.

Man.... that totally could have turned into something sexual. I expected better from you T7......

OP: It's like the difference between getting hit with a hand at 100 FPS and a whip at 100 FPS. The energy carried by each implement is different.

Just for illustrative purposes lets use f=m*a (and assume equal area hit by each implement), sure the hand and whip move at the same speed but their masses are different. This is the difference between the two. Although pain perception is different there is more energy in the whip and all that energy must go somewhere. Some may be lost to sound and other inefficiencies but assuming equal energy losses the whip still has a greater amount of energy to transfer and where does it transfer to? The victim of course (which should teach them to not be naughty.....).

Anyways. Shooting at the same energy at the muzzle, a heavier BB will hurt more due to newtons first law (object in motion tends to stay in motion), this is because there is less energy loss over time/distance and therefore more energy to transfer to the target/victim after getting hit.

As for guns..... CT and Walmart are probably going to be your best bets. In Japan they have a 1J law so you'll be shooting at ~328 on .20's.... otherwise the dollar store or CT/Walmary will likely have what you're looking for. Sorry but my knowledge extends to only that extent. Not trying to be rude/elitist or anything but I really only have knowledge about "real airsoft" and not "crapsoft/softair".

What are you looking to do? If you want to plink pop cans or beer cans a pellet gun (.177 cal/4.5mm) will do the trick but if you're looking for something to shoot at each other with (with proper eyepro of course) pretty much anything from CT will do..... I guess those cheapo spring pistols from CT will do the trick and should shoot within your wanted FPS range (assuming you're looking for those velocities using .20's), if not then dollar stores sometimes have those "BB gun" things that are like $3-4 and shoot 6mm BB's at like 100 FPS (if that), hell some people can throw a pen through a chrono faster than that......

well i wasnt meaning that cheap, as i have a cybergun ak aeg that shoots at around 250 fps with .12s, and its so weak, guys with springerss are beating me. more around the 150- 200 mark. im probably going to buy the aftermath knight cqb, anyone have experience with this gun??

how old are you ?

why, im 19

and if youre going to recommend getting age verified, i live in a small town, and dont want to travel to get age verified.

This doesn't make any sense, Why would an AEG use CO2? Also if your AEG is shotting 250fps with .12 there is something wrong.
But yes, cold weather does effect co2.

Also stop spending money on crappy softair. Wait sometime and purchase a TM...something more reliable.

that was not what i meant, i was going to buy a co2, and would be playing in cold weather. there must be something wrong with my aeg, although it is crap that costs around 70 new.

it can barely dent a can

Im full of tacos and Im whiny and not feeling it. I'll get my perv on later.

also ive looked on every canadian website, and other than 007, where do you get TMs???

I would tell you but you said you were not interested in getting age verified.

Don't buy anything from Canadian Tire or Walmart it will crapout on you and leave you wishing you had that money back to invest in a better gun, please trust me I know this from experience.

A lot of people consider JG's to be absolute crap but for $250 or so you get a gun that is far better than anything you'd find at Walmart or Crappy Tire. These guns don't have the same quality or quality control as some of the more expensive brands so there is a higher chance of getting a lemon, but I have read about many people who are happy with their JG gun. If you understand that this is a plastic gun and needs to be treated gently, cleaned and cared for it will perform well for a long time. The other benefit to JG's is that they are TM clones so it will be easy to find upgrades, replacement parts and mags.

I know you don't want to hear this but if you are actually 18+ it is well worth getting age verified just do it and you won't regret it. Find an AV'er make an appointment and hop in a car, bring a friend they can get AV'd too it'll be fun... ROAD TRIP!!! It is very easy to do and you'll have access to many AV retailers not otherwise available, and a large selection of guns. The classifieds are also good, if you're patient and do some research you can find a good used gun for a great price.

The most important thing is to do your research, find the gun you want eg. M4, Mp5, G36 ect., this should be based on your body size and playing style. Doing your research does not mean starting a thread saying hey guys is this gun any good? It means searching this site and others for reviews on the gun. Put in the work and you'll be rewarded.

Edit: don't be too concerned with FPS an inexpensive spring will easily fix a hot gun and your retailer can probably get it shooting in your desired range if you ask.

You need a spring change then. Either that or your compression parts are fucked up.

Get your hands on an M100 spring which should bring you to ~330-350 FPS, otherwise if you're looking for something lower in the 1 Joule range, an M90 or 1J spring should give you the desired results. That's assuming the compression isn't broken though. If that's the case you'll need to get a new compression set, piston and piston head (and while you're at it I guess it might be a good idea to change the cylinder to a ported one if it's not ported, a new cylinder head).

I totally understand some people may live out in the sticks and don't go to the city often so when you do take a trip to a city with an AV rep present I guess make an appointment with them or something, hell maybe you could meet half way or if someone is passing through/nearby because of work or vacation it's a quick 5 minutes and painless.

PS: From what I understand avoid all aftermath products except for the Kraken and Broxa as those are really the only "half decent" guns from Aftermath.

An alternative is the Tri-shot shotgun from CT. It's not the greatest and not worth paying full price for it but if you ever catch it on sale it's a pretty good buy. As well there's the Crosman Airmag C11 (comes in 2 flavours, Airsoft and .177 pellet) it sometimes goes on sale as well and a decent performer (apparently a lot of people keep them as secondary sidearms) make sure you buy the right one cause being shot with .177 is not cool.

AEG's work better in the cold than CO2 ever could.

ok thanks i wont fix this gun, because even the body is crap, i hit the barrel on an empty cardboard box and it snapped clean off. yeah, it doesnt have one metal part in it. I will look at getting a hot gun tuned down though.

i was looking at a jg but it had no top rail...

which gun were you looking at? Most of the time you can get rails to put on the gun.

a sig 552. it is rebranded as swiss arms, but i looked and it is made be jg, but every rail ive seen costs 50 or more, not really wanting to spend that on a 200$ gun

I own a Sig 551 and I have this on my gun
http://www.airsoftparts.ca/store2/in...oducts_id=1171

This is not my gun but it shows the rail installed.

Edit: check out this thread if you like the sig http://www.airsoftcanada.com/showthread.php?t=61850 there are lots of things available for the Sig you just need to look :)

question: why are all sig mags clear??

Sig mags are clear because thats the way they are on the real steal, lets you easily see how much ammo you have.
This is what I meant by doing your own research I don't mind answering some questions but the info is out there look it up for yourself

alright

although, I cant seem to find the laws for buying internationally. will one get across the border?

will one what get across the border?

a rail will, but the sig won't, customs will claim it for their collection.

This page will tell you what you can and cant import Importing Airsoft and You - Cleaned

alright i was looking at buying a gun from asia, but im scared it wont make it across. However, my friend got a full black gun from california, it came fine, it had been disassembled but that was it. hmm

DON'T ORDER A GUN FROM OUTSIDE OF CANADA!
If you do you are taking your chances, it may make it through, it may show up in pieces or it may be seized and you'll be screwed.
If you have to have to an all black gun up your price range and you can find them, if not get a clear one and paint it.

Edit: Crashonskis It seems you have failed to read this thread >>> http://www.airsoftcanada.com/showthread.php?t=40318 <<< ^^^ regarding importing to canada. Don't be lazy!
This thread is found in the FAQ section go there and read some threads they're very informative.
All the info you need is out there try searching this forum, reading the FAQ's or googling ect. you'll be amazed what you find. You'll also get answers that are better than
yes or no because you'll understand why it is yes or no.

Edit: crashonskis how old are you?

was this directed at me?
btw I DID read it, and pretty much every thread I can find (or am still reading).

Edit: The way you quoted me just before saying this makes me think that it's at me.

No no Wayne, my apologies... it's directed to crashonskis who likes to ask a lot of questions without trying to find the answers for himself like a big boy. I was using your post to show that you gave him the answer to his question, but then he just came back asking the same thing again.

ok, gottcha.

well it seems that you guys arent listening. I read hundreds of threads on the subject, and from what I saw, the only way it could get through is is it slipped past customs without being searched. HOWEVER, my friends gun is all black and had been opened and disassembled at the border, and from what I had read, this simply doesnt happen! You also dont seem to be doing your research, as my age is posted ON THIS EXACT THREAD! be careful no to be a hypocrite, and if you dont want to answer my questions, dont! just dont bitch about it abd make my day miserable!

also, I wasnt asking the same question! I was musing over how this could happen, because that thread said it couldnt!

Chances are if the agent who inspected the package is found they will lose their job.

Second, that is pretty blatant smuggling not to mention that it's a gun that's been taken apart, if I were a customs agent that would totally raise a red flag for me.

If you're really 19 use some common sense.

Finally, do you ever want to work with children or the elderly? If so then you probably would want a clean criminal record. ie. Smuggling charges aren't cool. Ever want to work as an Accountant? Engineer? Teacher? Doctor? Lawyer? All those professions (and more) have requirements for entrance into their professional bodies/associations and if you can't get entrance you won't be able to practise.

Oh wait.... what's this? Someone was arrested for smuggling guns into Canada? Unthinkable! Your one single anecdotal case overrides any other possibility!

Link to actual article is dead but it happened last year.

alright thanks, but I meant that they disassembled it at the border

Simply put, it is illegal to bring or ship an airsoft gun across the border (edit: without the proper licensing that retailers have), customs will not intentionally allow it passed, and will confiscate it, and you may face criminal charges for attempting to "smuggle" it in.

As has been said many times, do not try it, it is stupid.

Some parts can be imported, the thread that has been linked about 4 times now explains this.

However these parts will only make it across if they are not shipped with restricted items (like a gun or receiver for a gun), and if customs doesn't take it for the hell of it.

crashonskis

Your friend's gun was not disassembled at the boarder. If they find it they seize it. Figure it out.

I know you said you were 19 but you act as if you're 13 so I thought I'd give you a chance to come clean.

I think it's a "really good idea" for you to buy a gun from outside of Canada, heck buy 2 ... no get 3. Invest all of your money on buying guns from outside of Canada, "thats what I think you should do".

Edit: Just go get AV'd if you're actually 18+, lots of all black/metal guns to be had on this very site with no illegal smuggling attempts.

oh well i decided im going to buy the jg sig 552. btw, im 17, i just thought no one would help me if i was underage. sorry to cause trouble, ill just paint the damn thing black

and about the friends gun: thats really weird. it came and the bbs had been cleanly cut open ( im assuming to check if anything was hidden) and it showed signs of disassembly.

Right.. good luck with your gun Sig's are awesome I have one. The Sig body is usually painted dark grey, make sure you get a flat spray paint anything gloss looks funny and can give away your position.

Edit: lots of people paint their gun even if it isn't clear. Check out this thread http://www.airsoftcanada.com/showthr...ight=paint+gun See google and youtube re: How to paint your gun.

Lying..... :mad:

We do help people who are underage but the line stops when they ask about procuring guns. Hell even if you're AV'ed it can't be posted in the public sections it has to be posted in the Wanted or AV only sections.

There's lots of minors who come here asking for advice, we will help them (as long as it's a reasonable request and they've searched for it first) but we have to draw the line at actively helping to procure guns for them.

Also if the gun actually was disassembled (at the border) then someone clearly isn't doing their job and could be fired or possibly charged with accessory to smuggling or conspiracy to smuggle. There is only one redeeming quality that may get a gun released but by disassembling it, all is lost because it's also trying to hide the fact that it's a gun/gun parts.

NB: You may order non prohibited ACCESSORIES and PARTS from overseas/across the border but not guns. Read the FAQ on what items are prohib/non prohib. (ie. you can order barrels, stocks, internal parts, gearboxes, rails, batteries, slides etc. but you may not order receivers and pistol frames (and sometimes prohib length slides will get scrutinized more))

alright i got it. thanks guys

so yeah, CO2 loses velocity in cold weather....

yup, read page one for all the tech stuff.

Those "replica guns" he got busted for, were they Airsoft or just other "replica" guns? Just curious...

Please refrain from lying about your age as it is detrimental to your time here. Mainly because it makes me want to ban you.

Keep your nose clean, you be on very thin ice now.

[/thread] ??

ya, you might as well lock it now t7

Edit: mmm pie :)

I'll do it later Im eating pie right now.
