Umarex to make a 68 caliber, 5-shot revolver- HDR-68

[Ecapnation]

These are hellboy large...

[XEMON]

Well ... I used to 😅

But I'm planning on opening it and taking some measurements at some point ... I can post them and hopefully someone can do the same with a TR50 to compare

[BrickHaus]

Xemon. Sounds like you have a tr50 to compare.. any chance you'd open both pistols up qnd compare the valve assemblies? Im thinking the tr50 valve may possibly be the same and we already have an aftermarket.

[BrickHaus]

Whenever you get to that sheridan feed plug, toss one of these speed wheels in the bag and lmk what I owe ye.

[XEMON]

Ps: for the extra velocity, I'll let the "home defense crowd" make a "high power kit" (just like they did for the tr50) see how hot it shoot, then tame it down to field velocity.

[XEMON]

I'm out of hpa, so I couldn't test that, but the balance is nice with the 9ci ....
But co2 tanks range from 650 to 950 psi in function of the temperature (in my experience it's more 8-900 when I have measured it tempered weather, and I've seen it go well above 1K in hot days ...).
Also made a remote adapter so need to try that next time I hit the field.

As for the speed wheel, I'll print a few and make a sale thread for them sometime next week 👍

Definitely need the speed wheel on these cuz velocity drops early in the 12g. I wonder if it needs more pressure then a 12g can produce. I don’t want to run it remotely but maybe some HPA and cranking up the input pressure will get better velocity. Like an Air rifle reg or something adjustable. How dose it run on HPA?

[XEMON]

Ok, finally got a chance to test mine 🥳

Popped a fresh 12g in and here are the results:
- first shot with FSR: 230 to 250 fps
- first shot with round ball: 200 to 230 fps
The velocity remains pretty consistent until shot ~15 then start to really drop around ~20 or so ...

Got a few breaks, seam to be happening when the ball is small enough to slide forward into the cylinder ... Need to investigate further.

Here are some pictures.

Here is the "Umarex case":

here is the pistol with speed wheel and with a 9ci tank:

Detail of the speed wheel, it's the one I designed for the TR50, it's a perfect match for this one too:

I got to check it my battery’s were dead in my chrono. So i didn’t get exact numbers but it seems to shoot good enough to be usable.

[The Inflicted]

I put about 60 FS rounds threw mine and it shoots them well. Definitely good enough to use on field and get eliminations. Only thing I don’t like is toward the end of the 12g you get shoot down and it’s hard to vent to the leftover 12g to get a fresh one in with the piercing pin design. I might put the ASA adapter and run a bucket off the bottom. I would like to Try and make it an insta pierce. That would be cool. Maybe a CCI Bucket will fit in grip. Haven’t pulled it apart yet.

Velocity with first strikes on a fresh cartridge?

[Chuck E Ducky]

Well it breaks paint and has no velocity adjustment. So close yet so far.

Mcs is supposed to re send. Just a bummer being paint teased

[BrickHaus]

Bummer COB... You still getting them, or are you thinking they may be gone forever?

Rushed home to open my delivery. 2 HDR68's. Even got a tracking email saying they were delivered to my door. Looked everywhere, no packages. Fed Ex delivered to Maumee, Oh not Sparks, Md. What a bummer
