Aselkon

Generic i guess, but what can be said boys?

Just picked an MX-10 up for a song at a local auction.

Good ones are very good.
There is a Aselkon group on Facebook that has a lot of info.

I bought my other half a used MX10 a couple of year's ago and now in hindsite I wish I had not bothered , The pressure regulator was all over the place settling at 120bar then 80bar ( I thought my chrono was bolloxed) even after I stripped it and hand smoothed/honed all of the spring washer's I even asked Robert Lane if he could do a custom regulator for it but no was the reply ,The only way I could get it to group in any way was to take the shroud of and the air chamber to shroud clamp of and then it would do maybe 25mm at 30 meter's but 250mm left and 300mm low from point of aim , In the end my other half sent it to Liquid Steel to sort it out but at an extra cost of £140 .
The Aselkon facebook page is now ok but in the beginning one of the moderator's was unknown at the time a senior member of staff at the Aselkon factory and would sternly dissagree with any negative comment's towards the Aselkon product's until complaint's were made and he was found to have removed (50+) negative comment's he could not argue against and then ban the person complaining from the page, So he was removed himself.

Yes, i´ve figured as much.
Wine n water kind of deal, sorts of.

I my particular case it doesn´t really matter which, i´ll get it sorted if out if so.



On that note i´ve for the first time actually run into a PCP rifle that´s got me up the proverbial wall, and that´s an Evanix (Duk Il) Hunting Master AR-6.
Barrel doesn´t carry any choke what so ever. Slugs out at 5,60mm (in other words large). Shoots perfectly fine as i shove the pills in there one by one by hand, spreads approx 30mm on target as soon as i use the "revolver" magazine it sports.
Chambers mic´s to 5.70mm.
To be aware of this type gun is known to BE accurate. Just not.. this one, for whatever reason.

Stock it carries like "an extra"/second chamber just downstream the cylinder, on the barrel. Something i made away with thinking that i really didn´t see the reason to.
To keep in mind here is that the common revolver, as most of us know it, sports a "swaging diameter" sorts of choke as the pills leave their chambers - before entering the barrel.- since when cartridges were introduced just about. Really REALLY old revolvers, as i cap n ball, amounts to about the same thing as you shove the pills down the mouths of each chamber, pill gets "swaged" to size in that case too. For them we always aim to have the chamber mouths an every so slight amount larger in diameter than the barrel.

On this one though the pills are dropped into the cylinder from the front, nothing of the sorts above going on what so ever.

Shot 5.52mm slugs and pellets first, doing reasonably well at 30 meters as long as i hand fed them to the barrel. Then pulled a few pills from 22lr ammo, taking the micrometer to these told 5.70mm diameter approx.
Iow a rather tight fit for the cyl. Fired away and indeed accuracy improved, slightly when using the cylinder as firing platform. At this point that added chamber was made away with and instead the thing at first just sported a more common leade.. to be increased/modified to a VERY "soft" leade... then back to using a 5.60mm chamber again (5,62).
Nothing seems to help and TBH i´m starting to arrive at wits end here.



Being unchoked it of course lends to slugs well too. Fact is, more so than pellets really. As fas as that cylinder tho...



Indexing? Oh.. trust me, been down that route as well. Barrel is theaded in and so called end shake for the cylinder is set by how far in the barrel is threaded. So i turned this little "tool" to be able to use a Teslong and visually inspect indexing. On a sidenote here i have to admit to being surprised on how tight this could be set and due that how well the thing sealed up after all, moderator and all installed. Thought that end shake would make for a loud piece of kit moderator or no, but.. my bad. Doesn´t really sound all that much different vs any other PCP out there IMO.



No dice. All six looks like that so.. nope. No issues on that count either.

As it shoots well if i hand feed the thing and it all goes to hell in a handbasket as i feed it from the cylinder i for a long time there thought this must be a matter of "bullet yaw". Starting to debate that too though, but that being said the issue here sure lies SOMEWHERE!

But.. where we´re at i´m starting to run out of ideas. Bore looks just fine (and as noted shoots just fine), cylinder looks fine, indexing is fine. Leade, have tried various takes as noted.

That "added" chamber though, factory such, was obviously there for a reason right. If we compare that take vs the early FX barrels that were smooth for the most part and then just used a short piece of rifling thereon last bit of the barrel..

A numbers game?
To an extent i guess, but i feel we´re are atop that too? Turned a literal mandrel to check chamber diameter. The now "re-cut" chamber is on 5.63mm (as the grooves of the rifling come in at 5.60mm).
I even made me a "bullet expander" of the same type i made for "El-Cheapo" just recently to expand them slugs to 5,62-5,63.. At that rate any chance of "yaw" should be eliminated in my book?
Although i´ve tried a plethora of different pills by now main fudder is H&N´s 34 and 40 grain slugs. 22 caliber, of course.

While the chambers indeed are on 5.70mm the entry for the air other side of each chamber comes in at 5.00mm flat. That hole, for each chamber, is centered as well, of course.

None the less.
SOMETHING here is making them pills go ape as they hit said leade. There´s no two ways about that and i NEED to find out what n why.

Oh.
About forgot.





Piece in case. Sellers pictures. Thing is NIB (or case more correctly).

This information came from someone who used to review firearms, including handguns for UK but mainly US magazines. In the case of a good review being required, usually for advertising revenue requirements, on a revolver first it was checked to make sure he didnt receive a lemon for testing and then when it came to accuracy tests he selected the most accurate chamber and fired all shots through that. Rarely could the same accuracy be acheived from a revolver using all chambers.
I know we are talking airguns but the same principles apply to any "revolver" type magazines unless cost is no object. I realise its a stick magazine but look at the cost of the Steyr ones, and not all those are spot on

I hear you, it´s just that other AR-6´s seems way more accurate using the cylinder than the one i´ve got here.
Hence my frustration with it.

On the MX-10 in turn.
Seems like our postal service are out for lunch or something? Stated it´ll take 8 friggin days to ship it from up north down here where i live. Bolloks, to use one of you Brits wordings.

[Racing]

Well guys, i´ve had this thing apart bumper to bumper.
Wine.. water.. i guess?
As it turns out though if there´s ONE thing this unit WILL do it´s shoot! Cause... daaayyyyuuuum...
Doesn´t really care if pellets or slugs, this is one ACCURATE POS.

I´m getting ahead of myself here though. Will rest on this a few days to collect pics enough (resize via Pixlr) to present the story to you.

(N yes. That´s two Mercedes Cosworth engines and a good ol´ Chevrolet bigblock sporting carbon fibre stacks on a genuine Hilborn. Go figure..)
