With great power comes great responsibility. Awesome test. Data on the number of shots is invaluable. 88g could get expensive very fast but you got to admit its fun.
Thanks my friend. It used 40 gram CO2 for 7 shots. Thats 5,7 gram CO2 pr shot. The 88 gram CO2 canisters are very expencive. But its not for everyday use. Just me having some fun testing 😁👍
Hi Rune. JoNathan Scott is currently selling an adapter that replaces the charge indicator pin cap and comes out of the back sort of like a z chamber. The adapter has a quick connect for hpa. This allows you to run an hpa remote line so you can mount an hpa bottle on the side. He is also working on an adapter that will allow you to mount an hpa bottle or an 88 gram co2 directly off the back which will make a great shoulder stock.
😃 Wow...Yep this 88 gram tank delivers in spades😉👍 A 90 degree adapter or hose for belt type canister sling would make this configuration better handling 😃👍 Fun stuff indeed 😁 😎👍❤🖖 Love Brother
I just bought a twin co2 adapter for a umarex air javelin and it works great,Along with a mcs adapter ( modern combat sports. Saves $ on compared to an 88/90 gram. Cheers Brother.......
the twin c02 adapter will probably get u 4 shots instead of the 2 you'd get with a single co2. not sure about the saving, since its not apples to apples.
Yes its a true blaster now. The 88 gram canister makes it the king. Very cool to use 😎, but also very clumsy. The 88 gram canisters are expencive so its not something I will use on a regular basis.
Great power been waiting see reaction lol....been doing long with the hdr's big power.not as bulky as hp but bulky still but big power if needed.great vid...
Excellent Rune! Soooo ....why didn't the heat core pop? Glad it didn't! Aren't those numbers similar with HPA in terms of FPS Jules? I guess I am going to watch and taking notes? And then compare mine with yours. I was hoping not to go the 88 gram route because of the expense vs HPA. I have 3 PCP rifles here a compressor and 9L bottle. Was the CO2 restrictor in or out with the HPA adapter in? So glad I got one of these HDB....they are a Blast! 😂 The HDR 68 and 50 pretty cool but this thing with the 16 round mag is the best.
Thanks my friend. I guess it didnt popp the heatcore O-ring because I lubed it well last time I had it open. Plus this marker needs a lot of oil, so I guess thats why 🤔. I think that with HPA at 1100 PSI you get even more power, maybe up to around 100 joule from what Iam told 🤔. Very cool marker, but I must find another way to put on the 88 gram canister. Its way to clumsy having it sit under the grip. Stay tuned for more videos my friend 😃
@@runerebel8441 That was a Uhhff DAH! First Blast was it not? I grew up in SE Minnesota in the 70s to mid 80s. Nor Cal since 85 Chico to be precise. SKOL!
@@runerebel8441 --- sure but seems more difficult. I think some kind of quick change to a 2x or 3x 12g would be the shat - appreciate your videos - this seems like one of the best less lethal platiforms for home defense for the $$$. Did you have to buy parts for the power conversion? Do you have the part numbers for those adapters? Couple other ideas: seems like you could make your own balls if you had a mold and some epoxy. 2. Have you tried a tube for quick reloads? Seems like half mag (8) tubes would make sense.
Thanks. I have an adapter from homedefnece-24.com plus I bought one from another shop so I can use 88 gram CO2. If I use the restrictor and a 12 gram CO2 I can shoot the hole magazine of 16 balls. Its a very cool marker and has good power if you remove the valveblock 😃@@1FeistyKitty
@@runerebel8441 - how did you increase the power? I'd rather have 6 or 8 shots with max power between weaker and 16 shots. a double co2 mod seems like low hanging fruit for someone to develop. Someone could design a quick change for co2, maybe a magazine built into the gun of 8g you rack every few shots. For home defense you need a decent mag. The ability to reload quick is a big plus. The ball mag seems simple and effective. Also wondering if any coating might help the ball seal better and not jam the gun. Thanks for doing what you do. Your videos are informative and easy to watch.
Thank you. Iam glad you like my videos. Yes 2 or 3 CO2 canisters will be a much cheaper way than the 88 gram CO2. The powermodding (tuning) dont cost anything. Just remove the valveblock and restrictor and you have max flow of CO2. If you want to use 88 gram CO2 or tinker with other options then you need the adapter you see in the video. You can buy it from www.homedefence-24.com I have not made any spare tube for holding balls. But it might be a good isea if you use bulk CO2 or HPA. With a single 12 gram CO2 you dont have enough gas for a reload.@@1FeistyKitty
I was under the impression that 88 gram only added capacity, not power? The chrono numbers don't lie, of course, I just wonder how much pressure these are firing at? Surely HPA would be comparable? If not at 850psi, then surely 1100psi?
For a puppet valve the volume dont give more power, just more shot. But the spool valve in these markers dump a hole lot more CO2, and they love CO2 in liquid form. I guess the power on the first shot is abouth the same pressure as 900 PSI if not more 🤔
Hey Rune, I'm going to buy the HDB 68 within the next days and would like to know which modifications and tuning-parts are needed to get the maximum out of the HDB 68?
Hi my friend. No tuningparts needed for the HDB68. Just remove the valveblock and restrictor and you have max power. If you want to try 88 gram CO2 or HPA then you need adapters for it. You can buy the adapters from www.homedefence-24.com 😃👍
@@runerebel8441 so there is no shorter valve pin needed? Do you know if there is the a difference between the 7.5j and 16j version when restrictor and valveblock are removed? Or do both reach the same power then? Thanks for your help!!!
hello rune I've been following you for a long time but I'm a bit shy so you know how it is..I wanted to ask you I just got a 7.5 joule HDB 68..if I connect a 1100 psi tank to it without tuning how much power do you think it can reach roughly in joules?
Hello my friend. Iam glad you like my videos. HPA and CO2 needs a more or less open valve to get any sort of power from them. HPA more so than CO2. The marker will still shot if you use it as a stock 7,5 joule with 1100 PSI HPA. But I guess the power will be lower than if you use it with CO2. Its best if you remove the valveblock and restrictor. If you do and you use 1100 PSI then you will get over 90 joule with heavy balls 😃👍
thanks rune x your advice I learned a lot from you, from HDR 50 to HDB 68 .... I will take inspiration from your videos to see how to remove the valve block from HDB 68. GOOD EVENING
Ahahahahahahahahahhahahahahahabahahaha epic shot lol😆😆😆😆😆😆😆😆😆👍🏻😝😝😝😝😝😝 I can't stop laughing It's been two days that I'm very bad and you did me well with your first shot ❤️
It takes time for rapid gas decompression to degrade them from the inside-out. They don't wear out immediately but when they do at the wrong time it'll be a bad day.
@@ScaredyCatTactical Now we are confused ,which Co2 are you people referring to 12gr or 88gr since the marker comes standard with 12gr? Now we hear how nice the power is and everyone hailing the good first shot and the next moment you mention the decompression and the gradual wear which can happen at bad times (probably selfdefence) so my main query which exactly Co2 are you referring to 🤔 Thanks!!!
@@malefanematsie3890 I explained this is detail in my video ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-uWNvMY3W-2A.html but the summary is that once you start modifying these from stock and removing restrictors and valve blocks, more liquid CO2 floods the marker and will freeze/thaw the o-rings plus cause rapid gas decompression both of which will cause you to blow even a 70 or 90 durometer upgraded o-ring eventually. Stock markers of any brand that are low power aren't' so susceptible but power tune them and it's a big problem that sellers don't want you to know about.
Hej Rune, love your videos and experiments!! Is it possible to use the 88 Co2 tank on an unmodified HDB68 ? Or will it explode? Thanks for everything 👋
Thank you my friend. Iam very glad you like my videos. You can use it but no idea how much power it will give. Maybe a slight rise in velocity I guess. Good luck. Cheers 😃
