Huben K1 Initial thoughts...

I know!  My luck, I have ample air power, delivered at lightening speed with sub MOA accuracy and there's no rats willing to be the first to get blasted!  Bunch of cowards!

So today instead a HOSP says to his buds, "Here hold my beer"...

With the difficulty of buying pellets/slugs in just about any size, I see full auto as a problem. Might be fun, but it costs. Full auto is good for Youtube, but not for accuracy, even from a 25.

Yep, poor guy was definitely in the wrong place at the wrong time!

My thoughts exactly!  I think if I can perfect my double tap, there really is no need for full auto, other than just the thrill!  Now if someone could perfect the 3 round burst, that might be a game changer!  LOL!  But again, even the cheap pellets seem to be getting harder to find and their prices are creeping up as well.  It's times like this I think about going back to single load air rifles!

[mrbulk]

I wonder what the cheapest, yet most accurate pellet would be for the Huben. Not necessarily with highest velocity or greatest knockdown power or sub-MOA accuracy, just a fairly accurate, inexpensive and readily available pellet, even if it means turning down the power wheel and/or reg.

We all know these things can get up in the 80fpe or so neighborhood, but for normal daily times when one just wants to plink accurately in the backyard...

Have you tried the Crosman Premier Ultra Domed pellets yet?  I have not, even though that's supposedly what mine was tuned for.  Maybe I'll load up a magazine and see what they do at various velocities.

“Readily available pellet” ..that doesn’t exist anymore😂 Only pellet I see fitting that description are the crosman’s

Are you talking the 19-grain ones? Never tried...

So true nowadays...and I do have a couple thousand CP 14.3 domes I may try, might have to turn the power wheel down to almost zero though...

Same here, I clear out my local Walmart every time I see em.

Depending on your reg setting, turning down the power wheel might not be enough. I’d set it at 110 bar

[mrbulk]

Yeah my reg is set at 135 BAR now and Kelly was testing it in his shop at that setting before shipping it out - so at zero clicks the Crosman 14.3gr crawled out the barrel at 331 fps at first, then climbing to 624 as it settled in at the zero click setting.

So it may be doable, although for consistency's sake I would indeed drop the reg down to maybe 1500 psi as you suggest and go up a click or three...and get several hundred shots per fill then, I would guess...

[LegionAir]

Sounds like a plan. I know it will be hard to keep track of all those shots but if you can please let me know how many you get at that setting. I might sell this dang sk19 to get a .22 huben. Build quality is better on the huben

No, the 14.3 grain cheapies!  Domed though, not the hollow points.  The sheet that came with the rifle showed the regulator is set at 115BAR and the 14.3 grain CPHP's were shooting at 848 ins with the wheel set at 14 clicks open.  I have no idea how many clicks full throttle is, but 14 click sure sounds like a lot.  I had 18.1 grain JSB flying at 1050 fps, when I had it full open the other day, backing it off 4-5 clicks got it settle in at 950 fps.  So, I would think another 4-5 clicks down and the 14.3 grain CPUD's should be flying right around that same speed. 

This is what the sheet showed for the 14.3 grain CPHPs:

Click = FPS
1 = 346
2 = 360
3 = 379
4 = 388
5 = 416
6 = 439
7 = 459
8 = 491
9 = 521
10 = 546
11 = 607
12 = 667
13 = 774
14 = 848

Interesting that below 5 clicks it takes 4 clicks to increase 50 fps, then from 6 - 9 clicks it's increases just over 100 fps, but after 10 clicks, it looks like it gains 50 -60 fps per click!

That power wheel sounds like a mini exponential PE adjuster! How cool is that!? Sounds like you are having literally a BLAST with your Huben!  Very cool guns!

you have A Lot more clicks left!!!

So, I thought I'd try some of the cheap 14.3 grain CPUDs to see how they performed.  I had it loaded with 18.13 grain JSBs that were shooting at roughly 950 fps.  I had to clear the magazine of the remaining JSBs, so what better way to do so than to dump them into a spinner!



After reloading with the CPUDs, I turned the power wheel down 4 clicks to start.  I shot 2 shot then increased it 1 click.  It topped out at 1039 fps after 5 clicks up.  I then backed it off 3 clicks and shot the rest.  The regulator sure doesn't seem very consistent, the spread was from 907 to 923 fps.  I guess it could be settling in, so probably should worry about it too much at this point.

The sprinkler system came on as I was going out to get a picture of the group from the last 9 shots.  But it was about 1" edge to edge, not that great, but probably good enough for plinking tin cans!

 You have to adjust the regulator to get it into balance of the power wheel. Your spread shows to much reg pressure and to low setting on power wheel.

What should I set the regulator too?  It's at 115 BAR right now.  Should I take it down to 100 BAR or lower?

[Greg_E]

The only stuff that seems to be more easily obtained are the lead free pellets, that and cheapo Seneca brand that look really rough. The tins of Seneca I bought for my Empire X, look like garbage,but I'll try they to make sure. They will most likely get melted and turned into Bulldog chow.

I have found the best slug for Huben 2020 to be VN 28.5gr.  Regulator set to about 165bar.  Power wheel adjusted to 1040fps. Good for 38 shots. Super accurate and devastating on game.

The NSA 36.2gr are not good in the 2020.  They changed the barrel specs.  Actually I don't think NSA even offers them anymore.

Congrats on your Huben Paul. You lucked out that yours likes the 18 gr. I've tried mine on several different speeds and can't get it to group to suit me. But she loves the 25 grain redesigns at 920 fps.

Had a real windy day and shot a few groups but decided to stay at my zero of 28 yds because of the wind.

I shot two five shot groups with 4 different pups and they all held their own pretty good. Saved the Huben for last and it hung right in there with the rest of em. Was shooting 18 grain in the first three pups and of course the 25 RD's in the .22 Huben.

And shot a thumbnail size five shot group with the Huben at 46 yds on a rusty piece of metal.
