    I think everything is possible, but Huben stock is hard to beat – perfect shouldering and cheek weld. There are cooler looking stocks, but few are as practical.

    Not convinced that Umarex Hammer is any good unless I see dead elephant. Period. Dead elephant or Hammer does not exist!

    Does anyone have a recommendation for adding a picatinny rail using the sling hole in the front of the K1? I was looking at: https://www.amazon.com/dp/B01B6S8IOY but am not sure about the curve of the stock. Does anyone have a recommendation for a tripod and cradle?

    Thanks!

    @wyliecoyote – did you buy this in the end – I am looking at this but it is a bit expensive? did this fit ok? did you explore other options?

    not only link. Huben website is down for awhile

    Is everything related to Umarex Hammer complete BS? Really the more I see the less I believe anything about it.

    "his ranch of more than 7 thousand acres in the cal foothills,"

    7 thousand acres in CA?! 💫 That's enough real estate for good canon or even some air to ground toys. I think notion of "back yard friendly" changes somehow 💥

    I have spent so much money on air gun stuff and had a bunch of problems. I could have a couple top shelf firearms that would last a lifetime for the money I've spent.

    I wanted to get a Huben for a while but it poses a bunch of problems. How to service ? My other much cheaper air guns all came with plastic cleaning rods and more instructions. On my Maruader the end just unscrews and you can take the baffles out. The end on the Huben doesn't seem to unscrew. The rep at AOA said you might need to use some heat on it. ? you mean like a blow torch ??? no

    My first impression ….my .22 cleaning probe won't go past the baffle so the pellet is most likely jammed there. This would lead me to believe there is damage inside the gun.

    Air guns are over priced and overly flimsy and finiky. Money wasted in most of cases.

    that said, all guns jam and you have to know how to deal with that. Huben is not that hard to take apart – please do that and enjoy your purchase.

    Huben is about 80fpe .22 gun out of the box and will send any known pellet supersonic. Most people detune Huben  to upper 60’s fpe to send  33g beasts at subsonic velocities of about 970fps.

    Looks like your barrel gets dirty and slug get stuck so 3k psi of air can not move slug anymore. So pressurized air rips that plate.

     

    You’re lucky as that plate is less than inch away from your neck.

     

    I had similar issues with brass jacketed bullets with my preproduction Huben but in my case air escaped via mag air gap – not pleasant feeling to neck either.

     

    Looks like after 3 years of development they never tested stuck projectile – very basic test for any gun manufacturer.

    Huben will go supersonic with pretty much any off the shelf pellets and you will hear sonic crack. No silencer will affect sonic crack. You will need to tune it subsonic to reduce noise.

    You need machine rest and remote trigger. Not big investment. Pretty much any machine rest will hold air rifle POI.

     

    Any other way will have human factor  in it.

    FFP scopes traditionally considered sniper scopes for about 100 years now. Reason – shooter can do pretty accurate rangefinding using mil dots.

     

    as of past decade laser rangefinding equipment advanced very well. 

     

    For example defacto standard sniper cartridge lapua 338 will drop 303in at 990 yards and 312in at 1000 yards.

     

    So 10 yard error in range causes 10in difference in POI.

     

    it is pretty much impossible to establish 10yard range accuracy using mil dot at 1000 yards. All modern long distance shooting totally depends on rangefinders.

     

    all of that that said – ffp and mil dot is thing of the past for precision shooting.

     

    But if you are preparing for SHTF ffp is preferred cause when SHTF your rangefinder battery will be dead.Military uses ffp for that reason. 

     

    PCP air rifle is defacto not SHTF weapon cause your Chinese compressor will be dead and you will be eaten by zombies while hand pumping. So all of that said there’s no use for ffp on pcp air rifle.

    Please note that all factory Airgun pellets have different head and skirt size.
    head is sized for barrel bore and skirt has larger diameter than groove.

    Internal ballistic of airgun:
    head slides tight in to the bore and conical skirt assures straight fit. Once barrel is pressurized head keeps sliding  and skirt is expanded to engage rifling and provide tight seal.

    when using cylindrical sizer 
    1. You are pretty much assured that your pellet will get misaligned – head will wobble in sizer and enter it under angle.
    2. You are reducing skirt diameter. Your skirt will not engage rifling as good as factory one and air seal will not be as tight. Air will pass pellet and will create turbulence in front of pellet at barrel exit.

    none of above adds to accuracy.

     Alejandro thanks for posting. From your video here’s list of velocities:

    975, 943, 960, 962, 962 ft/sec

    this spread of velocities ideally should give you about 0.30” vertical group (per ChairGun  or StrelokPro) st 50 yards. Looking at almost closed shooting  range – wind can be ignored. 

    So air system can do 0.30” group at 50yards.  Your “all over” result is caused by barrel and/or projectile. 

    looking at pics NSA bullets have rear biased center of gravity. Some of target holes do not look round which may indicate keyholing caused by bullets loosing stability and wobble.

    Few years ago I machined Huben profile barrel from .22 match grade subsonic 1:10 barrel blank. I posted pics somewhere in one of k1 threads. It is sub 2moa using Beasts. 

    I’m less familiar with airgun’s but firearms use 1:7 and faster for subsonic ammo . 1:16 is way too weak for subsonic. External ballistics is same for firearms and airgun’s. It needs to be understood that twist by itself does not stabilize bullet. RPM is what produces stability and RPM is product of speed and twist rate. Subsonic speed is not that fast fast.

    Everybody is welcome to do your googling/reading on subsonic accuracy and twists. That topic is very well covered outside of air gun community. 

    I think you you guys are in search for mysterios super bullet that does not exists :)

    Time given my next barrel will will be out of 1:6 blank.  I’ll post once I do that.

    PS. From general physics – rain drop shape is most optimal for subsonic exterior ballistics,

    35 g hornady v-max works. You will need to cut off plastic tip and size it. You’ll also will need non choked barrel.

    Brass jacketed boat tail has no advantage for near sonic velocities:

    internal ballistics – needs too much air to engage rifling, hard to control exit velocity.
    exthermal ballistics – hevy butt makes it unstable, need a lot of rpm.
    terminal ballistics – no deformation or explosion, just nice round hole.

    If you live in US pcp airgunning is waste of money. It is slow, finicky,  awkward, very imprecise and unreal over priced compared to real thing. Unless you have excess of money and way too many real things.

    In many other parts of the world pcp airgunning is as close as you can get to the real thing.

    So, it depends on geography.

    Mine is #85, 10:1 subsonic match barrel. Got rid of my other air rifles, cause nothing gets close.

    It all depends of where the target is. If there’s neighbor window 10 yards from the muzzle – there are better places. 

    photo shows that you admire existence of your instrument but not functionality. 

    All of of that said, I imagine 150 yards of open space in front of muzzle and almost agree on subject.
    Almost because I think about  50 cal Barrett rifle and 3000 yards in front of muzzle.
