Wow ！A .22 co2 powered rifle with 850fps is awesome ！What you have done has inspired a lot of ag lover ！ Welldone Tyrone ！👏👏🎊🎊 Thanks for your work ！👍👍
Hi K Lee, Thanks for the nice comment it is much appreciated. Just a note mine is .177.
@@African-Budget-Pellet-Gunner 😜Sorry Tyrone 🙏😅. At the end of your video , I saw the Blue Star .22 pellet case, that is why I thought you were using it. But even yours is a .177 , the power is still outstanding . I mean it is not easy for a 4.5mm co2 ag to reach 800+ fps. Multi pump pneumatic and pcp is another story. 😂😂 l am sure a lot of ag lovers will follow your mods ! 👊👍
Thanks K Lee no stress glad I can share my airgun journey
Hallo hab ein paar Kommentare gelesen ich finde voll cool das du jeden antwortest hab dich auch abonniert. Ich habe mir ein Diana bandit .22 mit pressluft gekauft möchte auch etwas rausholen hast du zufällig ein Video davon danke für deine Arbeit💪👷💪
Hi Artur, Thanks for leaving a comment and joining the channel. I unfortunately don't have the diana bandit I do however have and have made many videos of the co2 version of the same gun which is the diana airbug. So if you have a look through the channel, everything that is diana airbug/Artemis CP1 will have the same principles that can be used as on the diana bandit. Happy shooting
What scope do you have on there? Thanks
Hi Chris that is a Beileshi 3-9x40 EG
I found the valve body can leak. The O-ring has to hold back nominal 850psi about 58 Bar. Dead clean, no pocket fluff, and silicone grease on O-ring and threads, not a lot, smear on with fingers and wash hands (not because it is nasty but it migrates everywhere, notably spectacles). When fitting an O-ring try not to roll it on but snap it in place so that it is not twisted, ping it like a rubber band. The valve is held shut by the CO2 pressure, so it is not prone to leaking but does like a hint of silicone grease on its seal. Never use anything harder than a fingernail on an O-ring, cocktail stick not a pin, they split and tear, or last 40 years handled right.
The factory assembly was not clever but we can easily make it gas tight.
I'm following this because I like what you're doing.
Hi Jeff thanks for the comment, glad you're enjoying the videos
I read yesterday that a 12 gram capsel has 60 Bar.
@@andreasnitsch8119 I have no idea of the fill pressure to keep it liquid but the vapour pressure of liquid CO2 can easily be looked up. 60 Bar is 870psig, but you would only see that on a very hot day. It would exert more pressure against the valve and so let less gas out, and so a form of self-regulation.
dont use silikon oil on orings ?
Yes, you can but normal mineral oil will also be fine, the place you should only use silicone oil is on the co2 seal
Thank you Tyrone for your explanation. Today I drilled my artemis cp2. 22. I used a 4mm drill and drilled with a drop of motoroil. When it was done I noticed a burr on the edge of the hole in the inside of the barrel. I took a watchmaker file and carefully filed it away. The hole in the co2 valve had the same problem. The file fixed it . After this sanded with grit 600 and cleaned everything with brake cleaner. Everything works and tomorrow is testing day.
Again thank you so much.....
of the barrel
Sounds like you are ready for action. Let us know how it goes
@@African-Budget-Pellet-Gunner hi Tyrone, I think I am ready with my mods on my artemis cp2. 22.
Bought a ht-x3006 and measured 586 fps/15,8 joule. Is this bad, acceptable, good or very good. I am using gamo match 1.00 gram pellets. Except for the valve spring I did everything I could.
Drilled all the ports to 4mm.
Is there more I can do?
Have a nice day Tyrone.....
@@peterspeets9950 that is very good, highly doubt it will get higher than that, nicely done. I trust you are happy
@@African-Budget-Pellet-Gunner sure I am 🤗
hello I made the change like you for my cr600w that is to say the more powerful spring and the 3.8 mm hole. I did not touch the valve thread because many say it is not useful. the results are present I can shoot easily at 30 m with JSB 0.51 g. anyway, thanks for your videos. I hope the text will be understandable because I use google translate.
Hey @Acloque Kevin I am so glad for your feedback and that my videos were helpful. 30m is a great range for this powerclass and will give you loads of fun and also capable for hunting small game as well. Happy shooting
thank you for your videos, now with my cal .177, I gained 45% more power in pistol mode and 30% in rifle mode.... great👍👍
@Yo Nel you are very welcome, glad it came in handy
You finally got me buddy, bought a Konvolute of Airguns yesterday, and now i‘m owner of a Diana Chaser .177 😃. The magazine is shit but i‘m ok with that. Think single loading ist the better way for this gun.
Thank you for another great video and for all the infos you share
Haha you are officially part of the club. I am sure you are going to have endless fun with your Chaser, Happy shooting Andreas
@@African-Budget-Pellet-Gunner thank you buddy 😁. I‘ve bought some funny things the last weeks. A Weihrauch HW 100 Carbine, the Chaser,an awesome Crosman 1322 and a strange Umarex underlever springer made in Hungary from the early 70th.
So much to play but tomorrow i‘m out on vacation for two weeks but when i‘m back fun is guaranteed. 😇
I've got a .22 chaser coming soon and can't wait to open her up haha... wonder how well this would pair with the Safepac HPA mod??
@Daniel Short the chaser is fantastic and it is definitely possible to convert if to HPA or even PCP
Haha that text on that paper deurmekaar i bet that is zuid afrikaans im from holland i recognize some dutch words also the mod i def gonna try thnx groeten uit holland
Hi @Geertjan de laat yes I can speak Afrikaans as well and nice to have you here. I look forward to you trying out the mod let us know how it goes. Groete Tyrone
Hi, sorry for m'y english 😅 si how many joules you win with your update? You change the Spring, the valve diameter, and what Do you want to Say to the spacer hammer?
Thank you for thé video
Definitely add a spacer in the hammer before the longer spring. Longer spring will have an effect on your trigger as well
Hi, Can you tell me how many shoot with a CO2 capsule After all upgrade?
I get about 20 shots
I love the accuracy of mine and the power since I did your mod suggestion. (hard rubber hose boot behind the hammer spring). That added 50+ fps for mine. Keep em coming Ty!
Thanks G Whitfield glad you enjoyed it, and the hard rubber works great as a spacer
@@African-Budget-Pellet-Gunner yes it does...mine was a little bit too big and I had to go around the outside diameter with the dremel tool with a barrel sander on it but it didn't take long to get it down to the size it needs to be to fit in the hole. I dont know if I'll do anything else to it for now, I'm pretty happy with it just as it is!! Thanks again for the tip and the videos!!
@G Whitfield you're welcome glad it could be of use
@Jack Rowland yes you are correct, the spacer should have an OD of 10mm to fit inside the hammer and then the thickness is dependent on the effect you want
Your cp2 works like a charm. Mine is a pain when relaoding the pellets from the charger
@Jc dupuy I am not 100% sure I understand your problem, but I would like to help. Are you having problems when your pellets go from the magazine to the breech/barrel
And so I'm back again.
I'm planning to do a bit more tinkering with my 4.5mm soon. So far I've put a 7mm stack of washers inside the hammer, and I've also run some sandpaper through the action tube. I'm a bit hesitant to make the portwork larger, as you might remember I've already had issues with pellets/slugs sometimes catching against the port. Someone suggested with my Sig Spartan pistol that I should turn the valve stem down a bit to let more gas past the stem (not the entire length of course, haven't done it yet), what do you think of that on the CP2? And does cutting the valve body make a significant difference, or is it just for more consistency from one shot to the next?
Also, it seems you used a spacer and stretched spring together here. So I take it that's safe to do then?
As for the Spartan I mentioned, do you have any suggestions for the valve outlet size? It's a CO2 blowback BB pistol, firing straight out of the mag. Factory spec is 410fps, which is supposedly 3.1J. And reviews point to that advertised velocity being pretty accurate (if not understated). I'm not worried about shot count, as emptying the canister is already a bit of a schlep.
Hi Johann, I don't know the spartan at all. You can turn the pellet probe down a little as long as you don't go to far back and prevent the pellet probe from sealing. You can stretch the spring and put in spacers.
@@African-Budget-Pellet-Gunner I was referring to the stem inside the valve. When the hammer hits the end of the stem and forces the seat open, the gas has to blow past the stem to get to the other side (where the port is). So the idea is to turn the stem close to the seat so it has more clearance for gas to blow past. But of course the end of the stem must remain its original diameter, or the gas will escape.
In theory I suppose it could help but I think you might run into a problem with the stem perhaps bending which will cause the valve to become less consistent
Very skilled and knowledgeable 👍🇬🇧
Thanks hope it was useful
Trying to upgrade transfer port on SMK Victory CP2...
How do I get to it ???
Regards, Dave McLaren, Plymouth UK
Hi David, I think you are at the correct place. There is 3 videos I have done ss a series on upgrading the transfer port. Cool surname by the way
@@African-Budget-Pellet-Gunner
Many thnx, will check them out today, have an upgraded hammer spring also?? May take me over the legal limit but have fire arms certificate anyways.
Yeah, nice Surname and just a shame we don't have the F1 cars to go with it lol.
Stay Safe over there Buddy.
Will update you on the Mods.
You should be safe on the legal limit for rifles of 12fpe. Even with all the mods, if you are on co2 I think you will be between 10-11 fpe.
Hi Tyrone
Followed video and fitted uprated hammer spring and followed by 3mm transfer port.
All good with no problems encountered.
So, Thanx for the great tutorial.
Stay Safe.
Sounds awesome I am glad you're happy. Thanks for following the channel and support
Hey!
I will soon by a artemis cp2, but I can’t decide if I should get the 4,5 or 5.5 mm version..
do you think these mods would do a big difference to the 5,5 mm rifle?
@MWCars firstly you won't make a mistake going for the Artemis CP2. What is your plan with the rifle? Plinking, target shooting or a spot of hunting? If you are going to do hunting I would say go for the 5.5mm except if your range is going to be 15-25m then I would go for the 4.5mm. For mostly Plinking and target work, I would go 4.5mm as the pellets are cheaper so you'll get to shoot more. The mods will work on both equally as well
Oh and welcome to the club, you won't regret it
@@African-Budget-Pellet-Gunnertanks for the response!
I want to do a little bit of both 😅 mainly target shooting but also pest control.
I personally would go 4.5mm but either or will be a great rifle
Your chronograph and pellet relation is misleading.
Hi @neitho mich why do you say that?
blue star pellets 18.21 grains at 841fps = 28.61 foot pounds. picture is of the wrong tin of pellets...!!
Hi @kevin rimmer the blue star pellets are 177 and 8.02gr sorry if I had the wrong pic, above is the spec of the blue stars I used
Hi Tyrone. I done all this and now as soon as I put a co2 in it leaks really bad? Any help?
Sure @David Kirkman 2 things you need to do.
1. Cock the bolt and then load the co2, if it only leaks after firing the shot then your spring is too strong or your spacers too many.
2. Can you tell me where exactly the gas is coming out?
If you not winning drop me an email at tyrone8511@gmail.com it is easier to help you there
@@African-Budget-Pellet-Gunner it was me! I forgot the big O ring in the valve!
Glad you came right, happy shooting buddy
@@African-Budget-Pellet-Gunner Thanks for brilliant videos.
@African-Budget-Pellet-Gunner Try to increase the length of the valve stem, I'm still testing this thing and I can't say how much the power has increased, since the chronograph gives erroneous results due to CO2 vapor / .22
@SnatusQ this will definitely give you more fps as the hammer engages the stem quicker causing the valve to be open a bot longer just beware of 2 things, if the stem is too long the valve will not close and you will loose all your co2 after the 1st shot and also beware of hammer bounce stealing your shot count, because the stem is longer your hammer will open the valve a few extra times per shot you will not notice anything different in the shot you will just see your shot count decrease a lot
@@African-Budget-Pellet-Gunner
Now there is a problem that when installing co2, it all comes out through the barrel, but this is solved, you just need to cock the hammer and set co2, but at the same time, the power has definitely grown
Yes, the stem is too long hence it is opening the valve without the hammer being pushed into the valve. How many shots do you get per capsule
@@African-Budget-Pellet-Gunner I can’t say for sure yet, I tested 1 cylinder, but definitely less than 30, since the values of the frame counter were not clear, then I realized that these gas vapors interfere with measurements, the values between 16j and 19j, with a bullet 0.9 g .22
I am keen to see your results but 16J seems a little high but let's see what happens
Good work .
Thank you
Hi Tyrone. I am a big fan of your channel.Im in the process of getting a cr600w that i will convert to your specs.How about making a video on upgrading to a bigger co2 tank.We will shoot more and save on cost of the 12 gr capsules. Keep up the good work. Thanks Quentin
@Quentin Du Plessis Thanks for supporting and following my channel. The CR600W is an excellent choice as well. I might make a video to upgrade to the bigger co2 tank but don't really have somewhere to fill it here. Where do you stay
@@African-Budget-Pellet-Gunner I stay in Port Elizabeth.We got dive shops paintball shops here
Well sounds like I better get myself a co2 tank and make a video
@@African-Budget-Pellet-Gunner sounds awesome cant wait for that video.Where do you stay. Must have someplace to refill on co2
@Quentin Du Plessis I stay in Ellisras(Limpopo) so here the guys are serious hunters and don't tend to mess around with pellet guns too much. I know Potties(Mokopane) has a place to refill cylinders
I have the .22 version. Did all the mods but gained almost nothing. Its up to 526ft/s compared to 500ft/s
@Gilmore Harrison Thanks for leaving a comment. If you say you have done all the mods, please let me know specifically which ones you have done. The 500fps which you indicated above was that measured or assumed as the original? Are you using the long or short barrel? What pellets are you using for testing? If you can answer these questions I can try help you. Alternatively send me an email tyrone8511@gmail.com with details and I can help you there. Looking forward to hearing from you
I missed the 8mm hammer spacer, Was it in the other video and I missed it?
@scott phillips yes I actually started with a 4mm spacer and when I stretched the spring I added another 4mm
@@African-Budget-Pellet-Gunner hi Tyrone you stack two 4 mm spacers, but what diameter do they have? Are these spacers washers?
Outside diameter of just less than 10mm will be fine. You can use steel or rubber, to be safe, start with 5mm width and then gradually increase it. If too much you bolt won't cock or your valve is stuck in the open position
@@African-Budget-Pellet-Gunner thank you Tyrone. I already tried some nylon washers, together 5mm and my valve leaked maybe I choose a valve spring that isn't strong enough to push it back....
. So I will skip the washers and leave it this way
@peterspeets9950 yes, don't change that valve spring, that will not bring any good for you
Can a co2 rifle kill hog?
I don't think so, I think it is underpowered for hog hunting. I would say up to rabbits is probably the limit
Try a pcp rifle that's .45 to .50 calibre. You can kill almost everything. lol@@African-Budget-Pellet-Gunner
Definitely those big bore PCP'S can be used to hunt just about anything
Переделал в рср, теперь и доска в 30 мм, на 10 метрах, не предел :). Скорость 1.0 грамм, 270, 1.5 грамм, 255. Хорошая штука. Толькo z- клапан и немного мозгов применить. Добавил колбу 0,25. Всё веселье, обошлась в 200 баксов, не более :).
Awesome sounds like you are sorted, happy shooting
Nice work! How many shots u get out of one CO2 cilinder? Drilled mine to 4,2 mm and have about 20 good powerd shots.
Thanks @HS Knives glad you enjoyed the video, I get around 15 shots but I have a few additional mods. What fps are you getting from your CP2/Chaser
@@African-Budget-Pellet-Gunner i gave my old one away to a fam.member. I Just started over and as im sending this massage im reassambil my cp2 😁 on this one i drilled all holes to 4.2 mm, on the vaulve i left about 6,5mm of treads and counter sounk the inside, i pollised the inside part of the "pipe" where the hammer slides, pollised the hamer, pollised the trigger and streched the hammer spring from 7cm to 10cm. Im going to test it tommorow but i dont have a chrony so have no idea how much fps its going to shoot.
Awesome I think you are going to get plenty of juice from that, is it .22 or .177
@@African-Budget-Pellet-Gunner its a .22, and going to put the long barrel on and going to put a hawke vantage 30*1 reddot on it.
I think with those mods and 14.5gr pellets I would say around 700 -750fps. Maybe try out chrono connect app. Nice, what you using it for?
