Have spent a few days working on this thing, or more to the point figuring it out.
In doing so i believe i´ve got it to a point where i´ll hopefully see more reasonable muzzle energy. Where it´ll boil down is anybodys guess as of current but...
What i would really like to get across is the build quality of this thing cause it´s nothing short of insane. Really.
Whatever you bring the tools to, the thing is just "there" for lack of better words. Yes. Color me impressed.
Now. Idea here, from a practical POW, is to be able to toss regular Knockouts @ 25,4 grains. Out of a few different reasons really, so.. please bare with me here...
Again. No. This is not an exercise in creating yet another "fire breather". However, i do feel that the stonewall 40J from these things is selling it short.
Know well enough that if i can push them 25,4´s well into the thousands i´ll be content right there.
Yes.
Aware that the mags are "really" thought to work with pellets, but truth be told having tried them out with modern day slugs of the right diameter.. seems to work too all said.
A while back i came to fool around with an Evanix Hunting Master 6.
Yes.
The "revolver" gun. This holds pills in a similar fashion, just the mag is a revolver drum. Thus the pills are to the letter shot out of the drum in case, and there´s a lead up vs the rifling, and this is where it all went to hell in a handbasket.
Point being that i expect absolute accuracy out of my pcp´s, there´s no two ways about that. Trust me when i state that i really really flipped the coin in case every way you can think of, but.. result the same.
I even got to using a Teslong to observe the action doing its thing as you worked the hammer.. no ills. None the less, i couldn´t get that unit to hand me better than around 15mm at 30 meters.
If i on the other hand inserted the pills into the actual rifling, presented it as such.. one ragged hole and truth be told i never figured out why that was.
Is the Steyr in case different?
Remains to be seen i guess, but these days there´s at least a handful and then some pcp´s that "shoots" the pills right out of the mag where they sit and do so well.
Never figured that Hunting Master out as far as that.
It´s been said that the Steyr is a "pellet only" gun. Might be, have had that said to me before and apart from that Hunting Master those that have claimed all have had one thing in common.
They´ve all been wrong.
Rifling twist?
Yes. Of course, hence why a shorter 25,4 grain slug (for the caliber) might be the trick for starters.
Last couple of days have been loads about details. Have fooled around with the different "puzzles" as far as the belleville setup on the reg, and in turn have learned what that adjustment on the reg can and will hand. It´s in all honesty a rather well designed piece of kit in my book, again.. build quality whatever you touch on this thing is right up there.
What might present an issue, if any, is hammer stroke. Hammer is REAL short n light and is limited in both directions by them "bars" bolted to it that runs in tracks cut into the outside of the receiver. Cause no matter what spring tension is needed aaaand... again. That is a REALLY short stroke for the hammer to travel.
The poppet in turn, as i´ve replaced that, is supported in two places really (stock).
First up the bearing mid ways within the actual valve housing (which btw is NOT out of stainless but brass) and then this very hardened "top hat" that is sealed vs a bore with an o-ring. That o-ring strikes at least me as semi stiff, and thus (i guess) it becomes semi imperative to see to that it has lubricant at all times. Minute amounts does it i´d say but none the less for the sake of that o-ring it needs to be there at least.
So. This "top hat" registers vs a bore on the valve body, and thus the poppet is supported from a bearing point of view in two places really.
That top hat sets maximum stroke at that, and there´s ample amounts of it for what i´m asking at least (approx 5mm).
One thing that´s still a question mark is how it´ll react as far as its semi auto functioning seeing its new power level. Mind you, the hammer is "cushioned" at both ends via set in o-rings. Ie; no metal to metal contact possible even.
What DOES appear to take to some adjustment though is the spring preload on the actual sear. To little and the hammer won´t hook up. To much and nothing happens as you depress the trigger.
A matter of adjusting for the new found power too i hope. If not, back to the drawing board on that one.
Nah.
We´re there i´d say. Going to spend a few hrs tomorrow finishing that valve assy and hope to be able to assemble and try as that´s done.
As i presume most have never worked on a Steyr, i can´t but take my hat off for the engineering that´s gone into these. This is no doubt a quality piece from the absolute top tier and done deal. Hence their cost.
Worth it?
Well. That´ll be something to answer later on. Cause as i get the power out of it i want the next thing up is the accuracy to go with it and as there´s noone to ask as far as slug use (which would be semi detrimental at 800+fps i guess) i´ll ask for a raincheck on that one. Lastly the semi auto function on it as explained above.
Stoked? Anticipating?
Yeah, for once i actually believe i am.
In short tomorrow can´t come soon enough lads....

Today, you guys lucky and happy....you can buy upgrade parts off the shelfs.
Not back in early days, we had to fabricate diy:
I have couple "custom FX" parts from EuropeAirguns that nobody else selling.
This makes me think this is a EA own design and fabrication.
For example the one on right:

Understood @357calYou dont need FB to make it operate, you just need to be able to follow the directions. https://dntoptics.com/ and it's my two cents.

On souping these things up.
For the 25cal be aware that as you start getting into more serious porting on them for a 25cal you´ll sooner or later "break into water".
Ie; the transfer will end up running into the sealing "shelf" for the o-ring on the valve body.
As i wanted the hole dia for what i had in mind there was no turning back. So what i did was turn a semi thin steel shim to support the o-ring and we were good to go.
Now.
The P-15/35 and the M-16 in essence share innards.
As you´ve already found out the main culprit getting these to breathe is plenum volume.
At the time i had a M-16 i fooled around with, and i ended up fabbing a stand alone plenum on approx 140cc´s. Massive? You bet, but then on the other hand it sure delivered.
Being lazy i opted to use the reg pressure gauge hole for entry. Worked a million bux and in the end, even on that short a barrel, i was pushing an easy 125J and there was room to spare.
Idea was for a longer barrel, of course, but.. that kind of went nowhere for different reasons.
None the less.
The ticket to making these puffs stand tall is no doubt ample plenum volume. Them smaller bolt on ones simply don´t cut it if you really want to get things moving.

FX Crown hammer weight question
- By NAProf
- PCP Airguns
- 5 Replies
Hi bchannell,
Depending on the original caliber and barrel length, your new Crown Mk II could have come with two different hammer systems. The difference is in the spring carrier and whether or not an additional hammer weight was included. Be aware that the stock hammer (Part # 19039, called "Hammer V7") weighs 16.3 grams. In the .177 and .22 versions the rifle often came with the Spring Holder ( Part # 19902) shown below. That spring holder has a long cylindrical shaped protrusion which fits inside the spring to prevent spring binding under compression.
In this case no additional hammer weight was included.
One can buy a "Slug Power Kit" upgrade (shown below) which includes a different spring carrier (without the protrusion and indented for the spring to go inside slightly), a Tungsten hammer weight, and a pin prob with adjustable pin length. While the tungsten hammer weight is really only useful for the large caliber, higher powered slug shooters, the spring carrier allows one to add any of the hammer weights available for the Wildcat, Dreamline, Maverick, Panthera/Dynamic., and DRS to work with the Crown. I also believe that the .25 and .3 caliber Mk II's came with the newer spring carrier and one of the lighter hammer weights.
Below is a screen shot from a 3D model I made of the Crowns action. It shows the newer spting carrier with an additional hammer weight. Shown in the uncocked position. Also it only shows the cam on the backside of the Power Wheel.
Hope this helps.
Cheers,
Greg
