m3 .25 700m ..barrel tensioner yes or no?

do you tune with harmonic balencer or do you use it just for supression on barrel tenisoner , I think that is what you are saying about ring you made, can you show me where how it is on gun...but dont do that if it opens up for re-tune, messing with it causes re-tune I got that...man thanks for chatting and helping....I live In Arkansas , but was born and raised in San Joaquin valley Hanford Ca
I do use the balancer to bring groups in tighter, and the shroud helps quiet it. If your tune is pretty good now there won't be a need for a retune but you may have to re zero after the poi change. I don't have a ton of pictures but basically make the hole in the back of the shroud big enough to go over the tensioner with an oring or 2 in it. You need a lathe or somebody who has one.

Air Arms  TX200 MkIII FAC Plus at 50-Feet

750 sounds a little slow.
time for a rebuild?
Actually with the Vortek 12fb spring I put in last week I am getting 760 with no spacer and 10.3 AA. Yesterday the spring must have got setteled in as all of a sudden it started feeling really smooth and was shooting small groups at 20 meters.

Umarex  Notos with STX superior liner?

Finally. Got the 600 kit on and shooting. 1850apx psi. Getting 842 avg on 18.13 JTS a bit higher with JSB at 850-855.

With the .218 LDC 17gr averaging 880fps.
I already knew the superior liner shot these slugs very well. At 2200 Out of the 380mm liner I was getting great accuracy and could get 845fps if I shimmed the hammer spring, if I screwed all the way in a bit more. But it was loud and violent at 2200psi.

With JTS 16.08 I'm right at 899- 900 dead on.

A little higher with cuda 15 but the accuracy isn't anywhere near what AEA/JTS give.

CPHPs high 930s to low 940s.


It looks a little long. And that's ok. It's really the tiny receiver that makes the bottle and barrel look so insanely long.

I'm happy. I've achieved what I wanted, it's capable of 35fpe if I want. I was able to lower the reg pressure 350psi to get these numbers. So there is plenty left.
I've ordered the huben reg/block (dream) which is taken God forsaken long to get here from China. This will help with the blockiness and marred plenum. Wish I knew about the domestic source before I ordered this.
Minnesota is a good bit closer than PRC

Airgun Technologies  Looking for a compatible regulator for Aselkon Ravello RX5 ( 52 joules)

Messure the diameter end length of your original regulator. Then write to huma-air asking which of their regulators is closer to such dimensions.

If there's no one, exactly the same size buy the thicker closer and take it to machine it.
Thank you for the suggestion, but such an approach feels like a large industrial project given the limited local means and expertise available here. In the worst case, a local gunsmith could import the original regulator from Aselkon, just as they imported the rifle. However, this process might take 6 to 8 months.

Thanks again for your advice!

Skout  Skout epoch

Love my epoch !! Just a note here in case someone has a similar experience to mine. I got my epoch originally in .25 cal with a 25” barrel. It has always been spot on money. Great shooter. I bought components for.30 cal. In .30 I couldn’t get it to shoot for 💩. I mean it was utter 💩. Tried all kinds of settings. Then Scott (Motörhead on here ) pointed out that Skout had changed the .30 cal probe length, making it longer from the very original. I ordered a new pellet probe, which is longer and low and behold it shoots now. So if you have or end up in .30 with no accuracy see if you have a very short pellet probe.

FX  Impact M3 Tuning Advice (inconsistency)

Don’t I need to be at the “knee”? If I up the 2nd reg to say 110 and then dialed the hammer spring back, aren’t I not tuning to peak efficiency? Aren’t you supposed to almost max out the hammer and then dial back with the valve adjuster and that is what limits the valve open time?
Put the valve at 4 and leave it there until IF/AND WHEN you need some fine tuning.
You put the 2nd reg at 100 or whatever and slowly increase the hammer until your fps starts going up. I'd start the hammer micro at around 2.5 or a bit more. If FPS stop going up and you aren't at your desired speed you raise the 2nd reg, put the hammer back at 2. 5 or so and do it again. When your speed maxes out with the hammer adjustment about 5-10% higher than your goal lower the hammer back down until your at your desired speed. Some may do that until your about 10 fps above your desired speed and then turn the valve in a tiny bit at a time until the speed drops to what they're looking for.

Results  N50 & USARB Results 11/16 & 17 Open Grove

You did good Perry. A few more things worth mentioning, Keith had a Birthday so Happy Birthday, and a sad note our Champion shooter Bob S suffered health concerns and was not able to participate and hopeful the docs can get a handle on it. Prayers always help if you can, thanks.

Joe
Looking forward to the next match and to see our missing shooters.

N/A  Webley Hurricane vs Daisy 777

I have 717 and 777 , like the 777 much better even though it has the same bolt action feel .
I think all the 7x7 pistols use the same bolt. 777 has a Walther Lothar, (Lothar Walther?) barrel, adjustable trigger, wood target stocks, forged steel piston lever, higher front sight and steel rear sight with adjustable width notch.

Benjamin  My other first PCP - Donated Gen 1 Maruader .25

The best thing you can do for a Gen 1 to knock off weight and improve balance is to get with AGR, and if he will agree and your air tube has no corrosion, have AGR cut your tube and make into a hybrid. Hybrid meaning it retains the steel section in the valve and back section but forward of that it is aluminum. If you do this, you cannot regulate the rifle and the truth is that regulation is not the greatest thing since sliced bread for a hunting rifle.

Look close in this photo and you can see that my Gen 2 SL M-Rod .25 (The Beast) and my little Gen 1 M-Rod .25 have AGR hybrid tubes. Neither are regulated of course and they are strong shooting rifles. And accurate. And kill squirrels, rabbits and vermin dead.



My other two M-Rod .25s have JSAR full aluminum tubes and Huma regs and all the mess that goes with that but are very light sub 7 pounds rifles outfitted with the synthetic stock, my Cobra, JSAR alloy tube, Huma, Cobra valve, AGR lightweight SSG, Tim Hill short shroud:



Which is another thing that can be done, either purchase the Tim Hill shroud which I did or cut your own shroud and have it squared and threaded, which I did also to get the rifle shorter, about 39 inches. Maneuvers in the woods much easier and works well in blind. It is 39 inches long, 7.5 pounds with scope and a Limbsaver branded bipod attached, under 7 pounds with scope only. I did the hydrodip myself, Veil Camo from Dip Demon and One Shot Wonder base coats.
Awesome. Thank you!

HW/Weihrauch  HW95 rebuild

So I put a full tin of H&N's through it today. It shoots great.

The rifle really spits them out there with authority. It's smooth but it's potent. It's harder to tame than when it was shooting 600 fps for sure. Its no toy. It will knock a shotgun shell 30 yards if you get a good bite on it. It barely penetrated a shotgun shell before. Now it rips the brass right off the plastic.

By the time the sun set the pivot tension needed tightening and I could feel a little rub at the bottom of the stroke. It wasn't bad but it wasn't glassy smooth either. The trigger spring screw kept walking out and I had to keep turning it back in. The mounting screws needed retorquing twice.

I adjusted the pivot tension and took it out of the stock. You could see where the cocking shoe was touching the spring guide a little. I smeared a little more moly lube on it and dusted it down with some moly powder. It's as smooth as a baby's backside now. The trigger screw got a coat of hot pink nail polish. I think it's perfect.

I wiped out all the mounting point threads with acetone and torqued them over some blue loctite. Then mounted my old Airmax scope on it. Tomorrow I'll sight in the scope and see what the chrono says. Another 250 shots should determine if things are going to be groovin'.

If it will stack them at 690 fps like it did at 590 I'll be a happy man. We'll see...

Snowpeak  Power-up for a M60B .35cal (+ found factory faults)

do you think the shorter barrel has something to do with the louder report as well? i somehow thought that also has an effect in that way.

mine is not too loud, compared to a GK1 without moderator or what i experienced with the VULCAN 3 HP today (my one ear is still ringing!), it is still quiet. =)
Yeah the barrel length was also a factor.

Shoebox Tubing Replacement

OK, that helps . . . but it is still not correct, at least as I see it. And even though you did not "include" tank size in the math, it is inherent in the results as all the data (and thus the rate) is for a specific tank size, with filter . . .

700 psi in 66 minutes is 10.6 psi per minute (you had the inverse of that), and I like that unit - psi/min - but it is for a 74 cuft tank with an input filter that leads to higher volume than just the tank.

Mine was 7.6 psi per minute, but the tank was bigger and the input pressure was a little lower. Adjusting for those two factors I get:

7.6 x 88/73 x 110/105 = 9.6 psi per minute, so about 90% of what you were getting, but that does not take into account the volume of the filter, which we don't know but could guess is 1 or 2 cuft at pressure. One would lower the result to 9.5 and two would lower it to 9.3 . . .

Pretty close in value between the 13 and 15 tooth cogs - about what the math would predict which is 87% (if we assume 2 cuft for the filter, the estimated ratio of our two compressors would be 88%). I don't think that difference in speed either way would be worth a swap, if one had either one installed . . . I'm sticking with the 13 cog drives in mine.

Hope all is well, and have a great day!

N/A  Eastern European Curiosity

So, it's interesting to me that AGT offers Uragan and Vulcan - what are the differences between those two models of same manufacturer?
Someone already mentioned valving difference. There is one more thing that is different between Vulcan and Uragan - Vulcan is more top heavy than Uragan. Distance from grip to top is lower on Uragan and taller on Vulcan.
And AGT came out with Uragan 3.
