HDS 68 Full Power with Homedefence-24. 

Not as powerful as some other youtubers have, but the power gains using the Powerkit68 are impressive.

Great tips and detailed video. Thank you very much.

Just got my powerkit - very helpfull tutorial :)

Thank You!!!!! Good job!!!!!

Nice video Ben. It could be the temperature that makes it less "hot". I notised when testing my HDR50 that has the Powerkit50 installed that it gave a max 29 joules, this at 20C. When testing earliyer in a warm room (25C+) it gave as hi as 42 joules with the same slugs. You can also check the breach-seal. Shine a light down the barrels and se if you can se any light comming from gaps where the breach-seal pushes against the frame. Mine has a small leak there and I will try fix it soon. When I do I make a video. Keep up the great work. Cheers from your friend in Norway :)

I did this same mod to mine and although the results were pretty good, it was inconsistent. So, I did a couple more things…now, very consistent and even more power. -I took apart the selector valve and bored out the passage ways as much as I could without changing air flow direction or selector seal. I also very lightly buffed the selector and the top and bottom where it runs to make it smoother or less clunky feeling. -Then when I reassembled the selector valve I used an epoxy that I really like and sealed the grove and channel it fits in so it was sealed air tight. New, they are less air tight than my tshirt…doesn’t matter how much you increase the air flow volume if it isn’t delivered to the projectile. -then I disassembled the inner and outer barrels. On the ends of the two inner barrels, I put a pretty thin o-ring. When reassembled, the other end at the breech is the width of the o-ring further out…about a mm. Now I see no space between the barrels and gun when closed. Almost forgot…you also have to file about a mm or so off of the catch piece’s post because of alignment with the o-rings installed…if not now, it’s going to make sense when you reassemble. Now it’s as powerful as I think it’ll go without some higher quality guts. And, it’s very consistent. If it’s not sealed when you start it’ll only get worse when it gets colder as you shoot and the metals shrink…

Massive thanks for this video, made modding mine to +20J super easy!!

I got my power kits today, and they even threw in some German gummy bears 🙂

Salut merci pour ce test

hi, good video of hds unbridle course😀, it's really weird the result🤔, maybe we should recheck all the editing if nothing is not tightened enough or something else because the results at the chroni are disappointing 😔😵

Washers on the brass tube seals ?. You could try finding a male/female bush extension for the brass screw/seal/pop out indicator to make the chamber bigger. Mucho power. Need to file out the plastic case for it.

Did you also remove the little brass throttle in the brass feed tube?

Can you show the modification using the export valve. I can't find it on the shotgun. Thank you

So I got to the step where you squeeze the spring loaded part and get the valve assembly out but for the life of me I cannot get it to squeeze easily and come apart. I gave up and re-assembled but I may give it another crack. Am I missing something? I had all the screws out.

I think it might be helpful to try a heavier hammer spring or adjusting the one it comes with. It needs allot more air to boost the large bore rouns down the tube.

I wounded if Home Defence 24 will have a Powerkit for the HDX 0.68 shotgun??? Now that would be fun!!!

U have an idea what would happen if u let the powerkit completely away? I mean when u let this tube empty after removing the original valve?

Hello, how much joule I got when I only remove the plastic plug inside the Ventile at the 7,5 joule version? Did I get 16 joules then?

Now we just need an upgrade for the Umarex air javelin! I want to make this crossbow bolt go much faster than 400 FPS! Help me find something to increase the power on my POS Sig Sauer MCX as well, if it's possible plz also. The MCX is pretty sad for how mean and awesome it is.. I should have spent the extra hundred for the Virtus 22 caliber PCP version...

See if already have 16j and you add this power valve. What’s joules are you looking at getting

Avez vous enlever le petit restricteur en laiton sur la tige en laiton quand vous avez changer le nouveau kit power ?

After removing the reducer my fps went up to 331. It was a nice improvement from 200 fps. Maybe you replaced those brass parts wrong. Also mine is the 7.5 joul version.

You're definitely doing something wrong, because I only took out the restrictor and put in the exact same mod in the 16j version and mine went from sounding like a paintball gun to a shotgun. No means of measuring velocity or power, but from the same vendor who sold me as well as you the valve, I can put one of those large, freebie, bearing bits that you get with purchase clean through 1/4" plywood at about 30 ft away.. maybe 20 ft... And before it wouldn't even go through a plastic garbage can. Now it blasts a rather large hole through the plastic garbage can... Almost sounds like a real shotgun at night where I live in the hollar as well.

Put the throttle back in?

Thx for your videos. Well... Any ideas on how to best remove the old export valve once the slot head is a bit dinged? I heated the piece up several times trying to break it free, but no luck. In doing so the slot got damaged and I really don't want to totally trash it. The space is tight down there so not sure if something like the Alden Grabit Micro damaged screw extractor would help to remove it. ????

Cool video! You think this will fit in the HDX68 too?

What happened to the little Screen?

Wish I’d watched this before mauling the head on my valve because I didn’t know it was glued in.🤦🏻 Did you put the little brass valve back in the O ring at the end of the brass tube next to the barrel selector?

ARE THE FREDS OK

Hi mate @5.49 you removed that black piece. I saw another video where the guy took that piece out then put the gun back together. He got more power, so do you really need to buy the power kit.

Hello! I wanted to ask you about the very small part in point 6.06 of the video, don't you put it back together? because it is not understood in the video! the little gold pin thank you so much!!

Can you get these power kitsin the UK?

man you are touching that stuff like a nitro gel in top heat,, but it is the right wat to do as gunsmith,, just look funy

Hi bud can you steer me to the upgrade kit for the HDS? I cant find it anywhere? Thanks

Have you seen the new model HDR that’s coming out ? 68 cal 👍🏻

Hello Mad dog love the videos. Can you please tell me the piece that you warm up what is it called. As I couldn’t heat it up enough to get the valve out and now there’s no grip left on the valve two unscrew. What is the name of the black piece that you put over the stove as I need to get a replacement ?

at 12:08 in the video you moved a piece of paper across the bench. the paper hit a small piece of brass near the old pin. What was that piece of brass for?

Vaseline? You should have used Pellgun oil or White Lightning Grease; Vaseline has a tendency to get sticky after a while or freezes and becomes brittle if it gets cold.

This gun is just interesting because its the only gun you can shoot slugs with nails.In rest for defense with normal balls its useless with just 2 shots...and that small power.Your HDR tuning was much more impressive...

Was ist mit der einer Schraube passiert?

I have been looking at getting one of these for a bit of fun, I am hopeless when it comes to installing performance kits always end up with spare parts 🤣, if I get one and the power kit anyone fit them?

Hi do you have a website to buy from? I couldn't find you on a search

Hi what upgrades can I do I have the 16 joule version .

Curious, has anyone managed to create a bola style ammunition for this?

ALERT DUMB QUESTION COMING. i have .68 pepper and tear gas balls and vrx ammo will i be able to use those in my 16 joule shotgun?

il atteins 20j avec des dévastateur ou des billes caoutchou/fer

Try it with bola ammo

How snug is the ammo going down the barrel?

why not tune up your wallpaper?

Its the 7,5 joules version?

which Should i get the TR50 7.5 jules or HDS 68 7.5 jules? Then get the upgrade parts from Homedefence-24.

Whatever you do don't damage the freds.

Need shogun so they will go down for sure if need be.

amigo

Tu l'as simplement mis en configuration française : 16 joules ! Maximum en France : 20 joules !

In uk is the 11 joules legal

If i was to go shooting this in my back garden I'd have the armed police round thinking it was a sawn off shot gun . Very dangerous bit of kit.

You can shoot steel balls, aluminum balls, rubber balls hairy balls, skinny balls and many different😂

Is this uk legal?

Cuanto cuesta

I prefer a 9 mm

You don’t buy a power kit you but you just take a piece of plastic out I get 22 joules out of mine

désolé mais massacrer une jolie pièce comme le 68 pour je pense deux -trois j. c'est dommage

itll shoot marbles too ;) just sayin lol

Abra me en español

That thing looks absolutely useless for home defence.

You have the time and energy to be modifying guns but can't seem to comb your hair or fix your walls behind you ,just saying
