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

[BrickHaus]

Im just checking in as well. I thought these were to start arriving in May, so I wanted to resurrect the post. Anyone get a confirmation?

[Chuck E Ducky]

Nothing yet

[XEMON]

Got confirmation from KT that they will ship this month 👍

[Chuck E Ducky]

Yeeeeessssss!

[BrickHaus]

Im excited to try one out. Zoom dot delivery coming right up!

[Jonnydread]

I'll let you lot be guinea pigs and figure out getting them up to field velocity before I dabble. Please post results

[BrickHaus]

If mine throws a zoom dot at 250, its pretty much field ready out of the box. Though Im 100% with you there lol.

[XEMON]

I'll test and post as soon as they come in 👍

[scrounger]

if its 250 consistant out of the box most (nothing perfect) of the time would be a good thing
280 better but it is a pistol
you wont be "long balling" with one of these but more close battles/ last resort (like if me a havoc gunner).

latest video did not show them blowing balls up in the barrel..
still like to see more rounds in video to confirm this.
only disadvantage i see so far to add is the balls in the cylinder when in gun and holster carrying the spare are exposed.. can see some woodsball or counterfire cracking them

Just got shipped confirmation from MCS should have it any day now.

Eta Monday

[XEMON]

Just got my notification!

[BrickHaus]

Monday. Monday. MONDAY!!!!!

I’m going to mess around with it stock before I tear it down see what valve they use and see if I can’t make it shoot closer to field speeds.

Who makes the best First strike tipx barrels? I plan on turning one down to fit. Removing the restrictor, self defense valve upgrade, adjustable valve mod to bring the fps down. I plan on focusing on FS round performance. They are a more robust round and more efficient the open breach design is going to make it a gas hog. Worst case I can HPA convert it run remote and bump input pressure as long as the valve will handle it.

[BrickHaus]

My thoughts exactly. I want to shoot fs exclusively and make a fsr barrel work in it.

This is just gonna be a fun sidearm or troll shooter anyways.

You think a tipx barrel is the way to go? I was thinking q FSC barrel has more meat to work with, but I wasn't sure.

I kinda hope Williams the thirds tr50 adjusters work in these. Or some version of it will work.

Pretty excited for this janky shooter. Lol

[BrickHaus]

I was watching videos of first strike rifled barrels, and they drop velocity by 20 fps so I wonder if you can simply pull the restrictor, qnd add the rifled barrel?

Adjustability is still a must, but Im thinking the rifled barrels will slow stuff down a lot.

[BrickHaus]

I got mine. Put some known brittle ass paint in it and it shot 4 out of 5 and blew one up. I couldnt get my radarchron to read any of the shots but my eye chrono says it shoots 250 easily on a fresh 12ie.

A huge note. It cane with 3 recievers. One in the marker, and 2 in the bag. So you may not need to buy as many as many as you think.

It holed qnd points super well. Any K frame user will find it natural.

The barrel is floating and spring loaded. Not sure how turning a fsr barrel down will work, but barrel internal finish is better than expected.

[BrickHaus]

Its honestly my first umerex so im not sure.

[XEMON]

Thanks 😁
I'm not gonna put my hand on mine till this weekend, can't wait ...

[BrickHaus]

Mines still charged, but Ill take a picture of the plug in a second.

[BrickHaus]

Ill admit. Getting that plug out sucks. I may cut a T handle down and epoxy it in there or something.

[XEMON]

It is, thanks!

I made a 3D printed wheel for them and people tested it on just about every umarex so far ... I'll test it on the HDR this weekend

[Chuck E Ducky]

I have a few of them for my 50 cal ones and they work well. Just got mine today (I really hate FedEx) but they seem to be hard on paint. This will have to be a FS only marker for me 100% especially if you want work it for more velocity. The spring barrel is an interesting concept. I wonder if it can be improved.

[XEMON]

Sounds like it's the exact same design as the tr50, but scaled up ... Maybe some of the high power mod for the tr50 could be adapted ...

[COB]

Spring barrel is necessary for the revolving cylinder. The spring keeps the barrel nose cone tight to the cylinder and moves in when changing cylinders. Without this nose cone pressing on the front face of the cylinder, the gun will fire the first 1 or 2 shots, but the weight of the balls will keep sliding the cylinder backwards during the firing cycle. I know this because someone filed the cone flat on one of the TR50's that I have for velocity reduction. After the second shot, the paw pushes the cylinder up/ rotates cylinder into position. As the hammer is starting back the paw releases. The cylinder rotates backward, and you fire the empty #2 hole. Also, Xemons' co2 knobs are awesome. I have them on all my umarex guns.

[The Inflicted]

I don't suppose you could tell where the break happened, could you? The cylinder gap is usually the tricky part with these things.

[COB]

Thats the place the paint breaks in the Roscoe Revolver.

[BrickHaus]

Yeah, thats likely where it was, in the transition to the barrel.

That being said. Ill likely shoot rounds. What would be q viable solution for future models? Have spring loaded sleeves in the cylinder itself? Then have a pusher but the cylinder sleeve up against the barrel as you pull the trigger? Or you could even have the valve port slide forward pushing the ball into the barrel then fire.

Either way. For 115. This thing is cool!

[COB]

The TR50 and HDR68 have a spring-loaded cone that fills the gap and keeps the cylinder from sliding backward

[COB]

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

[BrickHaus]

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

[COB]

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

[Chuck E Ducky]

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]

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.

[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:

i

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

[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 👍

[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.

[BrickHaus]

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

[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.

[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

[Chuck E Ducky]

I still have a few 50s but it will be a while before I get a chance to open them up. Work has been nuts.

[Ecapnation]

These are hellboy large...
