    Airgun Technologies VULCAN 3 HP sprung a leak. Advice needed.

    what is the right direction on the HP version? i tried pulling the regulator out with a long 4M screw that was screwed into the brass set screw, that would be in muzzle/bottle direction. to spread the extra lube that i have applied i was able to turn it and i guess that broke the o-rings (on...

    Airgun Technologies VULCAN 3 HP sprung a leak. Advice needed.

    This is what i think must have happened, not by the threads, but by sharp edges of the borehole inside the tube. because before i tried to pull it out, but was only able to turn it in the tube. so i guess, as others have said here as well, that the external o-rings were damaged. damn, that is a...

    Airgun Technologies VULCAN 3 HP sprung a leak. Advice needed.

    Hi everybody, my AGT VULCAN 3 HP sprung a leak, after degassing and while refilling. air slowly, but audibly escapes from one of a little boreholes on the plenum tube. there are three boreholes, the leaking one is on the height of the regulator, the one in the middle. has anybody a clue what...

    How to calibrate the YONG HENG 300bar auto-shut-off gauge?

    Hello everybody, in my compressor the gauge does not return to zero when there is no pressure on the line. So it is a bit off (it shows 80bar, when there is no pressure), which of course leads to an early shut off, below 300bar. (which i can see from several tank as well as gun gauges.) since i...

    Huben The most economical modification of HUBEN GK1 pistol Picatinny solution

    i did it like this on my GK1 quite a while ago and the off center drilling is to create a cavity for the slightly protruding degassing(?) on top of the block.

    Casting ammo from lead-acid batteries?

    That sounds like the reasonable and sane thing to do. =)

    Airgun Technologies Testing slugs with the VULCAN 3 HP .30

    thanks, i have no way to test it, so it might all be just glitches. got even higher numbers on a few shots recently...so maybe the chronograph is junk.

    Taipan The Saharan Mutant

    this is interesting. and let me state, this is not in any way a judgement, but i am really curious what the appeal to this color is? what are the associations?

    Airgun Technologies Vulcan 3 HP .25 max fpe?

    would you please explain how you do that, i have no reg. tester and so far have been flying pretty bling with it, and still am trying to find a reasonable tune for the ammo i want to use. sorry to read, that you are still struggling with the rifle. i do not think anything i can say would be...

    1st time slug casting went very well and was fun too.

    thanks, i've been trying to inform myself about casting routines and what to watch out for and also what causes what problems, so it was too much of an trial and error process for myself. with the hollowpoints i was actually quite surprized that they dropped so easy. i was expecting worse. for...

    1st time slug casting went very well and was fun too.

    hi @sonnysan, thanks for the comment and tip. yes, i am aware of the 'finned' projectile, i realized too late that there was tiny lead splinter in between the molds sealing surface and so the whole lot of 8 slugs were lost. i later sorted them out, but wanted to show my true results. i've not...

    1st time slug casting went very well and was fun too.

    when sized to .252 with the MP sizer they are a perfect fit for the mag. but i have just shot one mag for testing 'the feel', without any measures and only with a red dot on 15-20m distance with a stock, seemed similar than my results with other projectiles, but i will make better tests in the...

    Airgun Technologies Testing slugs with the VULCAN 3 HP .30

    casted slugs for the first time. i've used a recommended NOE boattail and ended up with 66.6gr. they fit tightly, so cocking is a bit harder than usual, but i got much better results power-wise, but not i have to tune the gun properly for these. besides getting my ears ringing (supersonic!) i...
