Finally got my 2200 up and running but...New valve and new cup but only shooting CPHP 14.3gr. at 450fps at 10 pumps! What should I do now, maybe a new hammer spring?

I have received a Notos CRK in a trade and wonder how hard is it to remove the factory muzzle brake as this one is toast from last owner.
Looking for repairing cheaply, big money an issue.
thanks

I started to see the fx pocket crono sale in the forum. I had seen some show how they had attached it to their barrel. I can't find anything in the search now. I thought I would start a thread. How do you attach your FX Pocket Crono V1 to your rifle?
I just ordered mine for my Gauntlet. Thanks RS

Testing

Here are three Daisy rifles. Two 753’s and one 853. The 853 stock is made of Elm. One of the 753’s is of Tiger Maple. The other is “I believe” made of Honey Locust. It’s a wood I am unfamiliar with. Heavy, bright in color, oily, and has a different grain pattern. Check out the end grain. (last picture in the center) Also, It appears to me that all three of these stocks came from different manufacturers. All machining is quite different. The Elm stock is by far the thickest. Followed by the Tiger Maple stock. Then the Honey Locust. Different in every way. Checkout the pictures. Any other opinions on the Honey Locust? I’m not settled on it yet.

Been playing with numbers for an impact. Kind of wish UA didn’t talk me into a 22 cal. I’ve owned a .25 cal marauder 50 fpe w/ 33.95 grain JSB pellets. Wanting to try the 33.95 slugs from JSB in .25 cal or should I still with what I have?

Because our laws restrict power to 12/6 fpe for rifles/pistols it means that 77grn .357 pellets go somewhere between 180-250fps. I 3d printed some pellets that then have a .22 pellet pushed into a recess in the front and these weigh about 19grn and travel at between 360-500fpe which is a vast improvement. Has anyone else tried this?

LRF thermal scope and non LRF thermal scope, how will you make a choice ?

Just want to share my vector continental 6-48x56 and vector sentinel x pro 10-40x50 scopes. For me the best bench rest scopes because of its fine reticles, and very small floating dot. Suitable for our br25m target paper here in the philippines with only 0.5mm center target. The 1/8 moa click value adds a huge advantage over others that offers 1/4 moa. Plus the glass clarity of vector scopes provides a really clear picture of the targets and less mirage on long range shooting. The vector continental has better glass over the sentinel though. But with sentinels low price the glass clarity is more than acceptable. Couldnt go wrong with these scopes specially when it comes to bench rest shooting. Here are the links incase anyone is interested.

Lots of great deals folks, have a look around!

Since I discovered PCPs (a decade ago) I have been interested in ways to increase their air efficiency.
I have so far used the SSS and BStaley because of their simplicity, and not having advanced mechanical skills and tools (lathe, drill press, etc).

This is an AI report summarizing them.

All experts and spectators are invited to comment

-----------------------------------------------------------------------------------------------------------------------

In PCP (pre-charged pneumatic) airguns, SSS, SSG, TSS, and BStaley are all tuning methods designed to increase air efficiency by minimizing or controlling "hammer bounce".
Hammer bounce occurs when the hammer strikes the valve, and the air pressure forces the hammer back, which then re-strikes the valve.
This wastes air and reduces shot-to-shot consistency. [1, 2, 3, 4, 5]

SSS (Short Stiff Spring)

* Mechanism: An SSS uses a shorter, stiffer hammer spring that provides a gap between the spring and the hammer when uncocked. This allows the hammer a short "free-flight" before it strikes the valve.
* How it works: When the hammer rebounds from the valve, the stiff spring resists being compressed a second time, preventing subsequent strikes and reducing air waste.
* Pros:
* Effective at reducing hammer bounce and conserving air.
* Cons:
* The stiffer spring significantly increases the cocking force required. [1]

SSG (Stopping Spring Guide)

* Mechanism: An SSG evolved from the SSS by adding a spring guide that stops the spring from moving forward just before the hammer strikes the valve. This creates a controlled "free-flight" for the hammer.
* How it works: When the valve closes and throws the hammer back, the hammer collides with the preloaded spring guide, which absorbs the energy and prevents the spring from relaunching the hammer.
* Pros:
* Combines the anti-bounce benefits of the SSS with a much lighter cocking effort.
* Reduces the "ping" sound often heard during the shot cycle.
* Cons:
* Installation may require some modification of the airgun. [1, 2, 3, 6]

TSS (Twin Spring System)

* Mechanism: The TSS uses two springs, typically in a coaxial or nested arrangement, to minimize hammer bounce.
* How it works: The springs work together to provide the necessary striking force while dampening the rebound of the hammer. This effectively prevents multiple valve openings.
* Pros:
* Provides excellent control over hammer bounce and can improve shot count.
* Installation is often simpler than an SSG and may not require permanent modifications.
* Allows for lighter hammer weights while maintaining power, which can smooth out the firing cycle.
* Cons:
* Performance can vary depending on the quality of the specific TSS kit. [7, 8, 9, 10, 11]

BStaley (O-ring buffer mod)

* Mechanism: The BStaley mod is a simple, low-cost tune that involves placing one or more O-rings directly in front of the valve face.
* How it works: The O-rings act as a soft buffer for the hammer, dampening its impact and preventing it from bouncing and re-opening the valve.
* Pros:
* Inexpensive and easy to perform.
* Can significantly increase shot count and shot-to-shot consistency, especially on unregulated PCPs.
* Cons:
* Most effective when tuning for a lower to moderate power level.
* Can alter the power curve and may not be suitable for maximum velocity setups.
* Requires proper placement and selection of O-rings to avoid affecting valve operation. [12, 13, 14, 15, 16]

Choosing the right system
The best system for you depends on your priorities:

* For the lowest cocking effort with top-tier efficiency: The SSG is often the preferred choice, assuming you are comfortable with a more involved installation process.
* For maximum ease and simplicity with excellent results: The TSS is the best "bang for the buck" for many platforms, offering great efficiency with a very simple, often tool-free, adjustment system.
* For a budget-friendly fix: The BStaley mod is a simple and cheap way to gain a large improvement in shot count and consistency on many models, particularly when tuning for moderate power.
* For a straightforward but less-forgiving mod: The SSS provides an effective solution but comes with a trade-off of higher cocking force due to the stiffer spring. [1, 2, 7, 13, 14]

Building off of the great work that @DaystateRebel and others brought in the original homebrew fx chrono display thread here:
https://www.airgunnation.com/threads/homebrew-fx-chrony-display.1278760/

I've been working on a new display for the FX Chrono v1 (the one thats on sale now at UA) so I didn't have to use my phone during range days. I wanted something that was larger, visible in sunlight and could export my data after a session. I ended up finding a newer 7.5 epaper (eink) display from Seeed Studio and using that as the base with a built-in esp32c3.



The built-in microcontroller has both BLE and wifi capabilities so its able to connect to the FX Chrono as well as host a basic webserver for setting configuration:



And heres a quick look at the exported csv:


Besides looking for a quick way to reference session data and SD, I wanted the ability to quickly switch between gun and projectile profiles while at the range and see FPE calculations in real time beside the FPS.

Next Steps:
- clean up code and fix a few ble bugs that I've encountered with higher shot counts
- store readings to local disk instead of memory so they are not lost on restart
- reconfigure webserver hosting to utilize its own wifi hot spot
- clean up webui
- clean up code base
- and of course do some more testing at the range!

After I get through the above changes I am happy to post up the code and installation process to get your own v2 display up and running. I am also happy to provide a service to flash the epaper devices with the open source code if it becomes too difficult of a task.

My ask to the community (especially members that have more experience utilizing chrono devices and tuning) is, are there any other features or abilities of your FX chrono that you would like to see implemented or would help in your tuning?

Does anyone know where to get rainson pcps in the US? I would really love a Rainson Sky Blue.

I have 3 PCPs that just have all the O-rings replaced and I need to set the regulator pressure and hammer spring. May I know what the correct process is ?

I haven't bored you guys with any old-fart collector trivia in a while. So...here ya go: a Weihrauch brochure from the late 1950's:

1. Note the "Received" stamp on the front cover. HP White Laboratories did the very first published airgun velocity data for WHB Smith's landmark 1957 book, Gas, Air, and Spring Guns of the World. (HP White is still around...and still doing specialized velocity testing.)


2. HW's range in those days was only three models--the HW 35, 50, and 55, though there are multiple variations of each. All the guns shown here have the "long block" threaded rear section, thus dating the previous "short block" HW rifles to before 1959. The 55 and 35 variants all have Rekord triggers, but not yet the 50. In other words, the long-block action predates the modular Rekord Perfekt.

3. The HW 35 page describes the classic trio of plain, Luxus, and Export finger-groove stock options that were used for many years.


4. The HW 55 TF version - a modified HW 50 action with no locking lever - is illustrated on this page. The other 55 versions listed include the S with plain beech stock, MM, and MF. Also note a detail in transition--the 55 T on the front cover has a finger-groove fore end, while the 55 TF is shown with checkering. It seems odd that no "F" version of the least expensive HW 55 S is listed.


5. There are four versions of the model 50: base; M with adjustable trigger; S adding a fully adjustable rear sight; and SD with both open and diopter rear sight. Note the bottom line on this sheet, describing an optional deluxe stock with checkered grip and buttplate.


6. The detailed technical desriptions and drawings are outstanding. The trigger designs, the HW 55's tilting breech adjustment, and various other details are clearly shown.




7. This sheet also shows a variety of sights and accessories, including some items in transition. The 35 and 50 target versions have an older type front sight with milled posts Inserts. The HW 55 had previously used this sight, but now has a modern tunnel sight with flat metal inserts. Both sights have the same element shapes - bead, straight post, tapered post, and aperture.

8. The older solid steel "turret" style diopter sight ("Mikrometerdiopter") is optional for the 35 and 50. Again the HW 55 has moved on, to an improved "square" pattern diopter ("Mikro-Prazisions-Diopter!"). The optional Siebert adjustable magnifying iris eyepiece fits both sights.

Well, the cats out of the bag now lol, you can now see the new Marauder GEN3 at this year‘s pyramid air cup at the Benjamin booth. The Benjamin team is also competing with it. Should be fun and good luck to team Iconic.

Comes with 90 day Kraz Cool warranty. $1290 includes everything in the 1st picture. All new parts internally. $1150 for everything in the second pic.

I was reading around AGN and stumbled upon some opinions about which PCP manufacturer has been more innovative and is ahead in the field right now.

I don't follow the news and what has changed overtime., would like to hear from those of you who have been following all the changes.

Hi all,
I am starting to sight in my talon 177 and was wondering what power level would be best for around 20 foot pounds energy. I do not have a chronograph. I am sighting it in with 11.5 grain pellets but also have 16 grain pellets. Any advice would be helpful. I have it set at 5 power setting right now and it seems it drops from 3000 psi to 2000 with around twenty shots maybe less.
Any pointers would be great.

Just received my HW50S from AirgunDepot. After unboxing I noticed this line going around the action area. Almost looks like a tooling mark.

The only other Weihrauch I have is an HW98 and it is immaculate. Curious if this is normal for the HW50S? Thoughts?

I’m probably being a bit critical it’s just going to be a squirrel gun! But still…

Hey guys, just thought Id post a few picks of my new mountain camo stock for my HW97 from Craftsman vit custom stocks , pictures don't really do It justice looks awesome against the silver anodized action . Fit and finish are top-notch can't wait to try It out ( when It stops raining ) .
