Dedal stalker cleaning

I've got a Dedal Stalker disassembled that's needs cleaning and resealing with inert gas I guess.
Would there be any company who would do that. Preferably in the EU but with all that's going on sending to RU will be difficult.

Or selling a Dedal disassembled would be difficult I guess.
Should see the one just listed on eBay for $50. Can’t be legit but if it is, it’s a gift.

Outshooting the Gun?

Its easy to see if you are imparting negative actions on your rifle, and you only need 10m and a 24x scope. I put my rifles on a lead sled and watch how different cheek pressure, grip, etc relate to the crosshair moving. Different stocks and rifle design have different results. It has also helped me identify a lightly loose screw between the action and the stock.

FX  Hunting pallet weight 25 cal

For squirrels, even 20 grain H&N FTTs work well. I took 18 squirrels with them and lost none. Rabbits go down easier so I would expect the same on them. Coyotes, on the other hand, require more penetration. 1-2 lb animals need less penetration than 10-40 lb animals, in other words. I would use the 34 grain on coyotes or a larger caliber. You could use the 34 on squirrels and rabbits but it is going to go through about 100% of the time. No big problem as long as it's OK to hit what is behind the animal.

Diana  Can HW30 main spring fit Diana 240 ?

Unless I missed it, the most important dimension is missing in the op. The outside or inside diameter. Either will work when the wire diameter is known.

Length and coil count isn’t that important. Springs can be cut and reclosed. Length changes preload but doesn't necessarily indicate strength.

Comparing OD, wire size and coil count gets you in the ball park. Even then coil pitch/spacing and material can affect strength.

Ideally you need to know all of those dimensions and spring rate to know for sure if springs are interchangeable. Or you could just try it.

BTW I wouldn't worry about a broken spring until it breaks. Some go a long time.

Exterior cleaning of SCBA?

The typical construction today is the aluminum liner, the structural carbon and it's resin, a protective layer of glass and it's resin, a waist wrap and the a final protective outer coating of resin that can get chipped etc if memory serves. If no strands of any type are compromised there are no worries. I've back filled chips with 5 minute hardware store resin and buffed it out.

I'm the old head now and remember when wrapped hpa was 3k psi for paintball 😁 I still have a bulldog cylinder because it was so pretty.
There are fiberglass automotive repair kits that I bet would be a excellent thing to put on one of those tanks as a base for a nice paint job.

N/A  Muzzle energy varies with pellet weight, WHY?

For those that want some serious night-time reading, that only needs "high school maths", these three are good starting points:

https://airgunwarriors.com/resource..._Failure_in_Spring_Piston_Airguns_Tavella.pdf


https://www.researchgate.net/public...Spring_Piston_Airguns_-_A_Conceptual_Analysis

Bottom line is that spring guns are complicated because they are extremely dynamic systems with multiple interconnections between variables.
Change one thing and everything else changes.

In this case, the MSP rifle in question has a simple limit: the energy STORED in the reservoir. The barrel is long enough to transfer most of it to the pellets tested, so, since the small reservoir is limited, then all the ME's are also limited.

Gas spring'ed rifles may have two different paths, and it mostly depends on the design of the leade/chamber/barrel and the material of the pellet:
They will quickly accelerate a pellet but still help the pellet retain its shape, OR they will blow out the skirt.
Contrary to common perception, Tin (Sn atomic symbol) pellets are NOT soft. They are somewhat harder than lead pellets, even those that have substantial amounts of antimonium (Sb) in the lead alloy. Tin Pellet retain their shape better than lead pellets when shot from a spring gun and therefore, may exhibit better internal and external ballistics than lead (and this does not refer to Velocity).

Steel spring'ed rifles tend to shoot under smoother curves of pressure/barrel travel, because the STARTING pressure of a steel spring'ed rifle will be lower the the equivalent one in gas spring.

On top of all the normal complications, VERY FEW shooters are REALLY limiting their experimets to the "pop gun" regime (as defined by the Cardews). There is a LOT of dieseling (controlled or otherwise) going on in 98% of the springers (all those that use tars/greases for the tunes with hydrocarbon bases). You would need to use ONLY Teflon based lubes and or DRY lubes (Hexagonal Boron Nitride or Molybdenum Bisulphyde WITHOUT carriers) to actually be able to claim that you have "zero dieseling".

We are barely scratching/beginning to understand REALLY how spring-piston airguns work. That is what makes them interesting and challenging.

Keep well and shoot straight!

For fruit phone users asking about Strelok, a Q:
Why don't you buy a used older larger screen droid phone or tablet and have a peace in mind.
For a range time I have a Samsung Tablet-A (8") using probably for some 5-6 years. I don't know maybe $100-150 you can get one, maybe even cheaper.
Everything my outdoor activities are loaded there, including FX radar, Labradar, Strelok, Weathermeter, X-reload, and a lot more.
It has a large screen no need to scroll to see the full app, also a SIM card.

Is Stoeger's new PCP compressor a hidden gem?

What I have learned - with scopes also with compressors - in recent several years so many Brands surfaced, and after some 2-3 years most of these new Brands disappeared for whatever that could be reasons. Cloned, copied, rebranded products when came to the end of warranty claim there was just not enough business case to keep these alive.
For a long run, me personally I would stick with a Brand that was on the market in 2020 and still sells today.
Like YH as one example, but you can and shall do your own research.

My Basic Homemade Wind Indicator/Flag

I no longer compete in any form of shooting competition. But, I still wanted a single wind indicator flag for my home 50yd range. My Bench is setup in my gun/fly tying room and I only need slide-open the window to shoot my air rifles.

I will leave the tripod on the range but will keep the flag in the house and only put it out when I go out to put-up a target. That way the wooden portions of the flag will not warp and swell excessively. Bye the way, the pivot of the Indicator is a pointed steel pin resting against a flat steel rod inside the dowel.

The tripod is leveled on 2-axis and the balance of the Indicator/flag is very slightly heavy on the vane side of the pivot pin.

I like the Indicator vane to point the direction the wind is blowing.



If you would like to view my Indicator flag in action you can download the video at the link below. I don't have a YouTube channel so the vid. is stored on my free 'cloud' storage.

FX  Crown/Dreamline magazine questions

I have tried magazines from this maker/seller for my Royales, Streamline and Boss.
They work very smoothly and are well made
He also makes mags for Crowns, which I have not tried
Have any of you?

Umarex  Gauntlet 2 SL in .22 cal

I sold my Gen 1 Gauntlet. But when I had it H&N Barracuda Match were my pellet. Ended up tuning it down to 1800PSI using Huben Power Max-ATH. The 50cc plenum was perfect for a .22. Put a 0.7L bottle on. Had to remove the fore stock but that was easy. Don't remember how many shots I got but it was basically an hour of making holes in paper.

Hajimoto supertune kit is recommended. Better hammer spring and the Noring for the breech seal is an absolute must.

Extended magazines, like Hajimoto, are very useful. Easier to load and hold a lot more pellets.
Thanks for the reply I did not think anyone would lol. I did not know about the extended mags , but I don't really want the super tune kit I got this actually to not mess with it , so I could have something to punch paper with while I was modding my Zelos. See there you go pushing me down the rabbit hole as extended mags are not a mod. I ordered 4 more reg ones already. I got some Gold , and Chrome rust oleum , and a bottle of the 2K you pictured up. Going to bling it out all the way. The Zelos.
