Okay, got it...yeah it sounds like our terminology is getting crossed up. People typically use the phrase “all the way in” to describe the hammer spring being maximally compressed. But since you have tried moving it the opposite direction and found the shot count to get even worse, it sounds like your original setting was indeed at the minimum.

What we don’t know is whether this minimum setting is optimal for the new regulated pressure. When it was unregulated, you indicated it was working well over a pressure range of 200 bar down to 100 bar. What this would mean is, unless the regulator is set quite high—something north of 150 bar—the hammer strike is now too much and it is wasting air. This is a trivial thing to see with a chronograph by making slight adjustments to the hammer spring tension and checking to see if the velocity rises, falls, or stays the same.

Then what you want to do is find the maximum attainable velocity, and finish by reducing the hammer spring tension until the velocity falls just a little to about 95-97% of the maximum you found. When adjusted in this manner, it will use air efficiently and produce a stable velocity.

In the event there is not a sufficient range of adjustment to either go high enough to reach the plateau (max velocity) or low enough to see the velocity begin to fall, it signals the decision will need to be made to either alter the hammer spring (add spacers to increase preload, or shorten the spring to reduce preload, respectively), or change the regulator setpoint.

Thank you for taking the time to break that down for me.
I guess I will make a chrono my next must have item.
Thanks again

Thank you! This is exactly what I was looking for. Too bad I just placed an order from Wes in Canada for some other parts. I can’t find them on eBay but I guess I will just make another order with Wes.

No problem. They might come from the same place, the one I ordered on eBay came from Canada as well and was about the same price.

JDR · Mar 21, 2025

Mike Baker has one for $40 shipped. Reasonable price close to eBay's price. Dennis Baker had only one left for $35.

Yes I watched the video from Target Forge about putting a battery on a CS2. I don't want to do it exactly the same way but I like the idea. I will use the superior Milwaukee batteries, however

Figured you saw it but wanted to make sure. I use Makita batteries so I just bought the battery powered GX CS2. i think you will find you will never need to hook it up to a car battery if you have milwaukee batteries. I would just get the battery powered CS2 and swap in a Milwaukee base plate and call it good.

It would be cool to see where those settings put you with a M4. It would have to be ballpark. It’s too late now and I hope it doesn’t bite you but if you truly had a sub MOA gun, you should have kept that liner.

My friend has my old M3 but has decided to use the 700mm sup heavy liner instead of the superior liner that i used, i found that superior liner to shoot alot of heavy slugs very well and he said i can have it back once my M4 arrives.

I think K&L makes an adjustable probe holder? Or just bump the barrel assembly forward a smidge.

This JTS "Standard" started as one of the original "Testers" from about 3 years ago.
The internals have been a work in progress now having a Cobra valve w/ peek poppet, SSG devise and regulated too.
Full Blue print job, Trigger work etc rounded out the action modifications.
Glass an old school Hawke Varmint 2.5-10x42 1/2 mil having short eye relief perfect with the shorter LOP stock has.
The fitting of the JTS into an RH vintage Diana 75 stock done a few years ago & it turned out looking and fitting as if a factory offering ... So nice

OEM barrel was ok, but wanted match grade accuracy as all the previous work had the mechanical functioning just stellar being smooth and very low vibration.
Was using a KARMA .22 test barrel in it last year and while much better, still lacked what I knew rifle was capable of ..... So In went a RAW .22 cut rifling barrel at @ 23" w/ air stripper and a tensioned shroud having barrel held Very stiff !
It shoots near hole in hole inside 40y and still stacks em out to @ 80y using JSB 15.9's at @ 940 fps. The transfer choke knob still allows throttling the output down to the mid 500 fps range or anyplace in between.
On a 200 bar fill we are getting 5 mags ( 50 shots ) under regulation so the efficiency is quite good. Noise on just a shroud is a modest pop, screw on a moderator it gets shockingly quiet.

Previous thread with 1st barrel trial:
Airacuda maximised
Some other internal tweaks since has found another mag ( 10 ) shots in efficiency.

you can make a de-pinger with a piece of foam rubber, a bristle brush or even a piece of rubber hose that fits somewhat snug inside the air tube about halfway inside, it only needs to about 1-2 inches long.

I went with the bottle brush method for de-ping. I got one with a slightly larger diameter than that of my air tube. I then cut about a 3 inch piece and inserted it to a little more than half way on mine, so as to not interfere with my regulator. Works superbly. Added benefit of using the bottle brush is that it isn't affected by the pressure changes. Foam rubber, Styrofoam and things of that nature expand and shrink with the pressure changes resulting in deterioration of the material. I do not have any experience in cleaning tiny pieces of foam rubber or Styrofoam out of my gun, but I am positive that its not as much fun as shooting it.

Just wanted to share my thoughts.

Highlux makes some repro type scopes that are similar but the ones I've used I was not impressed with and I don't know how close they focus.

I borrowed a friend's expensive vintage 1904 sniper system for Vintage Sniper comps and it was "all" a bit primitive in nature compared to modern stuff. Honestly I would have preferred using my cheapest modern scope instead by a massive margin if I were able to have that choice.

Yeah these have nostalgia but it's just not my thing.

Right about 2-3/8” from the bottom of the turret housing to the top of the turret at the same elevation setting. Yeah, I guess I was thinking you could figure distance to centerline or distance to the bottom of the objective based on published data. In most of my setups the objective would be the limiting factor on how low a scope could sit, rather than the turret housing interfering with a magazine or mount. I didn’t think of how that could be useful when I took the other measurement.
View attachment 549047

Thanks a bunch. That does it.

Yes, for me, because I have to mount the scope rather high on the Crown because of the magazine, so far objective has not factored in--it is well above my barrel. Even mounting a 50 mm objective (the Ares ETR) did not matter.
On another note, perhaps I can lower the FX rings a bit to make up for this small distance.
You know, if FX made their cases a mere half-inch taller (or even 1/4 or 3/8), this conversation would not be necessary. Gee, they know people mount scopes, right? And for me, when traveling, at least, I like all the pieces in the case.

Thanks again. S7

Voice is the very first thing I deactivated, and the only other thing I change now and then is the dwell if I am pellet testing, which I haven't for a while now.

@RM.510bigbore Did you find any that you signed up for?

Not Yet.. I might just go and shoot some powder burner ground hog matchs out to 500 yards..There local within 2 hours...Im sure they will let me shoot me my Texan with all the Bench Rest Powder Burners...Im sure i cant compete with 2 inch goups 30 BRs at 500 yards,,,but i sure can have fun....And do it cheaply... I miss hanging out with the old guys in the Bench Rest crowd.... If the stars align maybe go to Utah Airguns Match...It seems to be the one... I like the idea of the desert..Nice for my arthritis...Flat driving from Ohio to Utah.... Im sure i have to find out ASAp and pre register and all that stuff..Im shooting somwhere this year for sure...

I'll tell you I've done this enough times that I should've learned... the last time I realized I had wasted an afternoon due to clipping I wanted to give myself a sound beating.

At least it only took you an afternoon, it took me effing 7 different types of ammo, and I was thinking, wow this sure is a picky gun

inconsistent velocities is not from a hammer spring problem that much is certain. I would be looking at the regulated pressure. If there’s no gauge , you’ll need to add one. If you have a regulator on an external source like on an SCBA tank use that to eliminate the onboard regulator. But if you’re saying your rifle used to put out X speed and now only puts out Y speed and is consistent it’s not a problem with the regulator per se. But it could be the reg has settled at a higher or lower pressure. Which would require hammer spring adjustment.

I have seen in a few instances on my own air rifles where I was hitting the valve too hard. This would cause the valve to bounce shut reducing velocities and swings in velocity.

That's good stuff.
I could make a dummy reg to seal the reference hole and fill the bottle to different readings.
Not exactly regulated but close enough for couple of shots.

I do believe it's all about the regulator. Unfortunately AGT didn't care for that stuff. It's not feasible at all to try and install reg gauge on a V3

Thanks

RM.510bigbore · Apr 13, 2025

I got another carrier tube and did a lil 200 yard shooting.. I need to get a bench built.. Shooting off ground hurts my neck..I'm gimped..I think I'll be able to extend range by 75 to 100 yards..So 300 yards range looks good for the future...Coldshot mil base works like a charm..

Anyone have this compressor?

I just purchased five "broken" units at a price worth taking the chance.

The water cooling circuit uses a clear plastic piece in the water jacket around the one cylinder - all five units this ring appeared to have stress fractured - either from heat or the coolant used (a bright pink/orange residue left in the tubes)

It seems to be a decent little compressor once repaired -

I have dimensions to make an aluminum replacement for the plastic part - takes a little effort to replace but not difficult - have three units running - need the same part plus a water pump for the other two.

Looks to have been offered by DMC here in California (who I bought the broken ones from)

Would like to find more information on the unit - would be great to find spec for the various o-rings and an exploded view but making do so far.

Thanks

While a "good" machine shop can "single point" the threads...
You'd better make SURE...he knows what he's doing !! If the threads are even just a little too deep, and the thread contact with the cap are too loose...filling the reservoir "could"...blow the cap right off !! No matter how tight you "think" it is.
See..."class 3" threads.

Be prepared to "spend".

Mike

That's why I asked here and not at a local machine shop haha. Figured someone here would know how to go about it.

Yes I did see a BSA Meteor Super GTR.22 made in Birmingham for around $170, but after researching it found out it had a Gamo trigger. I would think that it probably has a Gamo gas ram as well. Had a cold forged barrel. I watched some reviews and accuracy appeared only so so. I figured you can get a bone collector with similar wood stock and the Swarm system so passed on that one.

"BSA Meteor Super GTR.22 made in Birmingham for around $170"

That would be exactly $169.99 too much!
An Absolute DOG accuracy wise

Thanks so much for your answer. However I see I cannot order them to be delivered to Europe, where I live. Thats really unfortunate. I am looking for a good long distance ~100yard slug for my Vulcan 3 .22

I asked Krale to take a look at AVS and Silent Thunder Ordnance.

It wouldn't hurt to have more people asking about them.
