I got the UX Zelos in .22. from Pyramyd air, man, I'm telling you people, this is a serious groundhog killer. Paired with an Athlon Argos Gen. 2 and various types of pellets and slugs (H&N .25 gr. HP slugs, H&N Hunter, and JSB UltraShoks)... On one neighbors property I have taken down 11 groundhogs, all headshots. I got a twelfth one with a .22lr. On another neighbors property I knocked out five of 'em, using JSB 18.13's, H&N Hunter, and H&N Hornets. Seriously, this gun can take out some stuff, I have also dropped 3 crows (they will no longer come anywhere near my property sadly, plus I have taken a rat, and numerous rabbits (using JSB Hades Monsters, these guys shoot unstably out of my gun, and a few other rounds including JSB Monster Lights, and Monster Deeps). This was done with no tuning, so out of the box, this thing is a sniper. Umarex doesn't ship the gun with baffles (even though it has the space in the shroud) which is very disappointing. This thing need a moderator, it would be a good idea to pair it with the internal baffles and a moderator, but you don't need to worry about follow up shots (you can make the thing shoot like a machine gun with how smooth the lever is, but...) because it shoots one hole groups all day long at 45yds. Once you do put a moderator (I used, very successfully, a $1 beach ball hand pump, to quiet it down, then bought a real one) it is quiet, but it needs a depinger since the valve is quite loud. I bet that the .25 is just as good. I'll see if I can post some pictures for y'all.

Mine came with one but it would not work on my compressor whip line ( looked the same but wasn't).
I had to add another coupler to make it work so, I ended up just purchasing a whole new deeper disconnect with the correct fitting.

If it was the one with the threads there is a difference in threads with NPT and BSP anyways if it was the one with threads you do need another coupler I think. Most compressors us BSP threads as it is global standard and NPT is north American standard. So since most compressors are not made in America it seems to be BSP for threads. But I just ordered the one posted here above and avoided threads and extra couplers altogether.

Definitely 3600. Or 250 BAR

Reg leak i think. Needs to be reselaed

Yes, my dwell will raise or reduce speed easily. Mine is a sniper, .25, pneumatic hammer, latest version. Reg is around 130 bar, shooting AEA 29.5g pellets at 975-ish. Dwell will change speed 1000 - 950 moving it 1-2 holes.

Thanks! Hmmm I guess I gotta take a closer look at valve then…

I use this scale. It has a two digits to left of the decimal point when units is set to grains.

NICE

I would be interested in lower profile mags . Even if they are 10 or less in capacity. .25 cal .
One thing that has prevented me from buying rifles in the past has been mag size sticking out way too high over the action.

Thanks for letting me know, I'll work on a mini version

Funny you say that. I accidentally pulled the throttle cable a bit on a new build drz and oil starved it with a cold rev start and burned the cam journals out of a head. I bought a used head and it dropped a valve at about 9k rpm. Just bought a whole new engine and got a new gearbox too for less than I spent farting around with head 1 and 2. It's all about roi.

Thank you very much. I have all of their videos save to a playlist; even though I don’t have the RAW. YET!!!

Thank you. I will get one.

O yeah, no matter what your " gauge " say, shoot whatever speed your rifle do best at, i see speeds as only a general pointer.
My Two i some times shoot at just 96? fps but the day after 990 might be better for me, even if using same chrono and tin of ammo.

Also my nate chrono do not completely agree with FX, but even with FX old chrono and smalle V2 one i see differences in the speeds they will log.

It is like a steering wheel, you do not steer all the time, most often you are just in the middle making minute adjustments to go strait down that HWY

EDIT: often if i have been shooting 10 gr pellets and so been on a way low REG pressure, transitioning back to shoot 13 gr slugs, i on purpose set off on a low pressure i know will not give me the speed i need, and then i slowly work my way up from there to make sure i am not missing some secret " gem " speed. so often probe speeds between 880 - 1000 fps for the 13 gr slugs that is my general stuff.

I remember earlier in the season i found a speed way lover than the target, but things flew pretty dang good there, so i shot like 3-400 shots there before i moved on.
I think the reason might have been a freshly cleaned barrel, CUZ i have revisited that speed since then but not had the same " that’s interesting " feeling.

It could of course also just have been the weather, some times it mess with me, and i swear i shoot the best in wind VS the days where there are almost no wind or there is a little wind but it switch a lot.
Give me a fairly constant wind from 1 direction and i feel the best.

Well, I tried clocking in different spots, that moved the POI around generally, however the grouping was close to 3 inches at best from 10 yards. Without it under 1/2 inch. I think I'll stick without it.

Yeah, great shooting. I only got 17 groundhogs this year.

I doubt that's a defect. Likely just two of several iterations of the "same" thing.

Do they both perform equally well?

One on the right keeps blowing orings idk why.

Nice collection, congrats.

The last production versions had the slim stock like yours. Serial numbers were omitted by then, but should have "Mod. 114" at left rear of tube. Maybe its covered slightly by the stock.

Thank you, took the stock off to start cleaning it and found the Mod 114 right where you said.

Likely cause is that the design has a LOT of hammer spring tension placing a high static pressure against poppet stem. As pressure within gun reduces so does the force holding poppet closed. Get near the tipping point of air pressure holding valve closed and the mechanical pressure of wanting to open it .... Air in tank goes woosh !!! Or you start to get heavy hammer bounce.

Tho said, this is in play as well,
Now a worn poppet that needs a lot of pressure to seal up well will start weeping as pressure falls away ( Tank dump at some point ) where as a good poppet that seals well even upon filling may bounce at low pressure but does seal up when the stutter of a bounce event diminishes.

I have had several jams with the BinTac T9, I have found that by securing the magazine (I used a temporary electrical cable tie) you never get any more jams.View attachment 592849

The magazine fits loose. I put a few layers of clear gorilla tape on the back of my aea magazines to make them thicker.

thank you jps2486

I’d be tickled to death with that wind. Our norms are triple that.

BTW, the flag at the target tells you little about what your projectile will do during its flight. You might consider another flag 10’ from your muzzle. The close flag will help you a LOT more.

So my friend got the Himicro Alpex lite, and i just picked up the LRF for my oneleaf NV500 scope.

BUT !

We both run into problems with the damn thing actually working.
We can of course enter all the needed parameters, Checked and triple checked, but outside ( further out ) the zero distance we are both shooting too high VS what the scope suggest.

My friend shoot the 13.43gr KO slugs, and i have been giving the JSB Heavy a spin in lack of Hades pellets.
In my friends case the BC is right there on the tin, but i had to dig a little around in the interweb to find a BC for the JSB pellets ( 0.031 )

I have to admit this is a bit confusing for me, and for my not at all technically inclined M8 more than that.

So we can Zero for 30 M and everything is dandy, but then ranging and shooting to 50 - 55 - 62 M and suddenly our shots land 2 to +5 CM too high.
We have not tried shooting shorter than the zero distance.

PS: We are of course not ranging for something behind our targets, they are all large enough that we are not doing that mistake.
Ands we have verified distances with leupold range finder.

The way i see it my only option are to " tune " the BC until it fit CUZ clearly the scope think my shots drop a lot more than they actually do.


Thoughts ? Hints ?? Wisdom,,,,, much welcome.

If you zero at 30m and your shots go hight at 50m+, your BC coefficient value is incorrect. I know you entered the manufacturer’s published value. Over the years I’ve realized those values are often “approximately” correct. Furthermore, nearly all ballistic calculators are for faster bullets. So you have to adjust your settings to compensate.

To setup my scopes, I zero my scope, adjust the scope height for distances shorter than my zero, and then adjust my BC coefficient for distances longer than my zero. Below is how…

After zeroing the scope (yours is 30m), I would take a shot at 25m and check the difference between my aim and hit point. If the pellet hit higher than my aim point, I’ll decrease the scope height a bit. If the hit point is lower, I’ll increase the scope height a bit. I’ll take another shot and do the whole thing again until the hit and the aim points are the same.

I’ll repeat the whole process at 20m, 15m, 10m. I know it sounds weird but, I often end up up to 1” off of what I measure as the scope height.

Once that is done, you have to adjust your BC coefficient.

In your case, the pellets hit higher at 50m. That means the pellet does not drop as much as your calculator thinks it should. The reason is simple; your BC coefficient is too low. So increase your BC coefficient a bit and take a test shot at 35m. If the hit point is lower than your aim point, you’ve increased your BC coefficient too high, decrease it a bit. Repeat the testing until the hit point and the aim points match.

Then repeat the same process at 45m, 55m, 65m, …

You are done!

In my backyard, using ATN, I can hit sub-moa up to 74yards.

would this be good shooting rabbits and field targets?

The point of my previous post - which you just quoted - was that only YOU can really answer that.

Any sight will be good for anything at SOME distance. It's your ability with a given setup that determines what that distance is, and whether it's sufficient to be of practical use to you.

Somethings fishy with that estimate .... don't be shocked when they state it being a LOT more than that ... Hope not, but experience says otherwise.
