IMHO, a plenum helps the most when directly inline with the valve. Granted, we see shrinking ES and better shot counts with many plenum locations but our desire is to feed all the air the valve requires at the time of opening.

From what I see, this means greater efficiency, less wear, better balance mechanically and even a better overall sound to the gun as it fires.

Normally, we see the above benefits as well as ease of tuning, better accuracy and less pellet picky.

Of course, YMMV

I understand the benefits of a plenum. My concern was where that specific plenum mounted. I can't see how a plenum feeding through the gauge hole would be more than a very minor improvement.

I completely agree they need to be inline. I have multiple Huben Power regulators with inline plenum. Dream, as you know, has a 20CC and Max-ATH has 50CC.

I've got a couple g1/2 to g1/2 tubes that have about 15CC I've added to regulators without plenum. That was a very minimal improvement and the added length just didn't make it worth leaving in.

BRK Ghost is very similar to Impact M4 as far as i can see. Huma air plenum as well and simple tuning mechanism.But I don’t have any knowledge about BRK.

Hi all, i m pretty new here so appology if i miss some etique. I ve got 700mm panthera(.22, 34g hammer,slug pin, humma 1st stage reg set to 200bar, lot of weights on chassi...nothing special). I tried several reg setting(150-160-170-180), seems best results around 165 bar(166-167 on digital gauge), it give you 290-300 m/s depend on weather/altitude, 295 seems best for me thus i got no POI during day, i have mag(18+2-3 purge shots, 290 bar/360cc bottle) that s my experience from 4000 slug shooted already. I posted some of my groups upper here, if it is under moa,I can live with that, never shooted altaros tbh even o got them at home...too expensive for purpose i shoot(even for me who pay distributor prize)

I vote for for the irons.. but I prefer irons..I have a American tactical liberty Nova 22 caliber and it shoots very well. back when I could still shoot long distance,100 yards 3" groups with it on out to 160 at 170 I couldn't hit a 24" backstop.. just literally scattered everywhere..I got my Henry Golden boy and tried them side by side just to see if I was having a bad day..
nope pushed it on out to the end of my drive 1/4 mile and still hit good..
I came to the conclusion that the liberty Nova was just out of steam past 160.. I don't remember what it chronograph at .
hopefully someday I'll be able to try pushing my airforce Condor 22 out to a 1/4 mile.. assuming I stop shaking someday..
the Condor is the most powerful and simple air gun that I have shot..

Your approach is a good way to get into airguns - learn how things work and then make an informed decision on what/where you want to buy into.

I also believe that good quality equipment is worth while investing in and buy the best I can afford.

Just a comment on SD and ES numbers, I agree that they are an excellent indicator of (power plant) performance but there are other factors (like harmonics) that determine overall performance. Look at the whole picture.

Cheers!

Ive been shooting air rifles since i was just a little guy but recently i picked up these two for good prices on Pyramyd air around christmas so ive been just digging deeper into it since and glad i did! Quality will always beat quality, but sometimes my wallet feels otherwise haha working with what i got! Next is shooting groups and just letting the gun tell me what it wants to get the tightest groups i can! trigger work, harmonics if needed, clean/maintained barrel and crown and the most important ME! every shot, the same breathing, movments, timing, trigger pull, rest etc.

Had to find this topic again to ease @blackdog899 mind even further. Was testing mods last night with a .30. Was jumping between 75 and 100 yards. Came back to 75 yards to test the one mod a final time. Squeezed the trigger and poof, complete darkness out there. I left my scope set for 100 and shot the light to pieces at 75. Done for the night. Repairs made this evening.

FX - Impact m4 sling attachment

I've been working on a sling set up for my new m4. I tried a couple diffrent configurations but didnt like either of them. So this is the newest idea and I must say, it's excellent. I like it alot and it's gonna work just fine. If you need help or the hardware to do it, message me and I'll set...

Nice job. It's too bad that the Saber Tactical mount doesn't fit on the M4.

No worries bud! You can imagine what a pain in the ass it was to find it as the first person to build the setup

Please give a big thanks also to Justin Jacobson the next time you see him. I think he had his hands on getting this adapter designed or atleast to give the nudge to do it/getting it done.

They have the screw also.

Besides being an avid Airgun collector I also dabble in pocket knives and watches, all of which fall into this conversation. When it comes to quality in China, you choose whether or not you want something to be made cheaply or well. Your costs change accordingly this becomes very evident with pocket knives where you can get a Chinese pocket Knife for $10 which is a piece of junk or one for $500 which is made exquisitely.
Keep in mind that that same $500 Chinese knife would cost anywhere between 800 and $1200 if it was made in the US. Many of us in the US think that because it’s made in China it’s cheap and it’s junk. This is not the case. If you want something high-quality made in China they are very capable of doing so but it is reflected in the manufacturing price. A good example is the iPhone, it is made in China, but admittedly a very high-quality piece of engineering. You also have the additional cost of the vendor profit.
If the Hubens were made in the United States, they would be much more expensive. Keep in mind these guns are engineered to hold and work under 5000 psi of pressure. This takes tremendous skill, high-quality materials and very exacting standards. I have both the K-1 and the GK one and find that even though there are things that I would change or improve the quality of both is extremely high and they are both very reliable if used properly.
The days of everything from China being cheap junk are long over.

Not to long but this could be a viable option.

I checked the baffles again and may have found a mark on one so I reamed them all out about .008 larger. I also scrubbed the barrel which I usually don't do on airguns and then used a washer in the barrel band as suggested. It now shoots pellet on pellet at 10yrds! Can't wait for warmer weather so I can shoot longer distances. Now I'm going to tone it down a little to improve my shot count. Thanks guys!!!

One thing, I guess I did not mention. The barrel stripper also has an O-ring on it that fits into the ID of the shroud (#9 in PL). Make sure that is a good fit and in place on the stripper. If the O-ring is a sloppy fit on the ID the barrel and shroud may not stay consistently aligned.

There are no airgun restrictions in the Philippines. The customers I have in the Philippines follow the wrabf rules. There is no limit on pellet weight or the use of slugs.

The limits you speak of must be imposed by whoever is putting on the matches you choose to attend. You should go shoot with the other guys. Those that make rules to purposely limit advancement to support their own equipment never go far outside their own little bubble. Stop supporting them. It will stunt your growth.

Completely true! I think I am alone in our province that wants WRABF rules to be enforced. All the rest want tailored games suited for whatever equipment and ammo they have.

Anyway, I foresee a better future since shooters (in our province and region) slowly opening their eyes and minds to world standard competition but it will take some time. For the meantime I’me stuck with their rules except for BR25 HV using WRABF rules.

Thanks for the input Mike.

Huben Power has a new U regulator, ostensibly for Airforce.

300mm or shorter bottle (0.5L)
M18-1.5 on both ends

120CC plenum, oh my.

Now I wonder can I put this on a gun with a tank in the front? Incredibly ugly but 120CC of plenum...

I started to buy the parts end of last year to do this very thing. Now I just need the 120cc plenum tube n they make the complete unit. Would like to finish what I started but this might be the way I have to go

looks like O-ring 20 in the diagram above.

Click to expand...

Thanks. I found that diagram but I am pretty bad at figuring out which one was

Thanks for the help

Last week I was just in deep dive with firelapping my 6 liners and toke me a lifetime to finish the entire polishing process on these . This excercise a money cannot buy...
What I learned that the land-groove ratio is playing rough games with speeds and ES/SD. Because each can have their own loose or tight spots - independently.
Adding to the drama - the choke amount.
And I don't want to forget about HN or FX or ZAN lead compound - softer or harder.
So in my eyes - if you would push in a slug but half way only, and retract back, a couple from each Brand,
and measure with micrometer...
compare a blank slug with one that you recovered back from the barrel,
that can give some better answers.
Also a high power jewellery lupe for closer look on shiny faces will give some insights.

You are correct, there sure are! Thank you to all who responded!

No way to test so just trusting manufacturer but recently have used this product with good result: https://www.amazon.com/Airsoft-Sili...-1-spons&sp_csd=d2lkZ2V0TmFtZT1zcF9hdGY&psc=1 For o-rings I use Trident silicone grease from any dive shop.

I have a 25 cal taipan vet compact shooting about 45 fpe. Always one shot and done headshots at 35yds. I make a kissing noise and they look at me without moving for about 3-5 seconds. Gives you plenty of time to line up a good shot. I imagine a X from ears to eyes and aim at the center of the X if that makes sense. Helps if they are looking down slightly. I also find that domed pellets penetrate the skull best.

Hi everyone

did anybody tuned their zeus 72 for more energy?

are there any tricks like shimming the spring or after market tuning parts available for the zeus?

or heavier hammer weights?

any procedures allowing the valve to stay open longer to dump more air on the shot?

thanks

In my continued hot take on the subject I think it can be said that at greater distances (l
& leaving out external effects like wind, temp, etc) ballistic flaws will probably become more apparent.

My personal experience w this was w a bullet that looked great at 10, but was tumbling at 50. The slug was too small for the bore...pretty simple explanation even for my tiny brain.

Leupold.....

Does that brand have ANY scopes that has 10y parallax and a holdoff reticle with exposed turrets?

I can't find any.....

6.5-20 x 40...................no hold over reticle. Parallax range 10 yards to infinity. Target turrets. It is an excellent scope.

How many usable shots per tank are you getting? They say you can do 10, but wondering how usable those 10 are.

Click to expand...

The first 3- 5 are the best usable pressure range from 4500 - 3000
