    Hello.

    I am opening a new thread on bullets for K1. As many of you probably know, I designed a mold for K1 that MP molds is now offering. So far, many molds have been sold. Casting is a very fast and efficient way of making bullets but it is not the most accurate. This has nothing to do with the quality mold, it has to do with the procedure of casting itself. Casting involves high temperature fluctuations and temperature diference causes material to change form and dimensions when transiting form liquid to solid state, that is why cast bullets are never as accurate and uniform as swagged. Swagging is a cold procedure that involves swagging die that shapes cold (solid state lead) bullet into shape of the die using high pressure. Swagging is however a much slower process…
    I have been using Huben swagging kit for about two weeks now. The process is (as I already mentioned) slow but the result very rewarding. The bullets are extremely uniform (35,7 to 36,9 grain with my alloy) and perfect dimensions. The bullet design is a round nose, bore riding, boat tail. This shape ensures minimum friction in the barrel and best BC possible. With pressure set to about 180 bars, Huben spits them out at 300 m/s (just under 1000 fps) :). I did not have a chance to shoot them at longer ranges yet (bad weather) but they show great potential if they will be stable (I am confident that they will be). At 25 meters (27 yards) I consistently get groups smaller than 5 mm CTC. This promises under 1 MoA accuracy.
    The kit includes a guillotine for cutting the lead wire and swagging die. Because it is quite hard to get a 5 – 5,5 mm lead wire in EU, MP mold made me a mold so I can cast the slugs that I then swagge. This allows me to have any alloy I want. If there will be interest, MP mold can offer these mold in the future… I use a workshop 12 ton hydraulic press for swagging. This is an overkill but it is the press I have… The bullets can be swagged with hammer as well but I definitely recommend using the press as the wight uniformity is much better this way.
    Because swagging process is relatively slow and K1 is a semi auto arigun, I will probably only use there bullets when shooting form extreme accuracy. For plinking, MP mold is a good enough option and it is much less time consuming.
    I do not have any confirmation yet but I am hoping that Huben will also make these bullets available as an end product as I realize that many K1 user are not too thrilled to have to make the bullet them self :)

    I will share more details in this thread and I also intend to make a video on YouTube.

    Can you share some BCs and drop charts for long range.

    Of course, but I have to be able to get to my range… :) I assume the BC will be about 0,2…

    One thing you didn’t mention about poured bullets is hollowing. There are a lot of causes (cold molds for one), but think about the surprise you get, when you weigh one, and it is half of what it should be!

    Exactly! But that can be avoided with experience and propeler preparation.
    Thanks for the add-on.

    Gregor is there some restriction on bullets sales/import? Huben should be selling the bullets not a tool

    They are not the same but they are similar in design. I had some of those when I was making videos (244 yard shot), they are also the same as the ones Matt used used in his video…

    $320 ?? 

    That’s disgraceful.

    What is it with these airgun manufacturers that they think they can charge rip off prices etc ?

    Yeah I felt the price was expensive I was shocked tbh, a mould is cheaper and from my understanding not far off quality either. Still debating

    Yeah got the same email at first then tried locating 5mm wire, only found 2.5mm max so it’s really putting me off

    I do not know the price yet, seems that a lot of you already inquired about it.
    I cannot say if these are better than Huben bullets so far, the accuracy seem to be about the same, they might prove to be more accurate then Huben bullets at long ranges are they are more accurate in weight and shape than Huben bullets were (I don’t have any more, unfortunately).

    The actual mold for pellets (not from huben) seems a far better option financially and generally over all

    Too be honest I am getting rather confused by Huben and other members.

    Which bullets are made by Huben, the ones Matt showed from AirgunHuntingSA, the ones marked Huben sold by AirgunHeaven or something else ?

    Also, is the Huben K1 v2 barrel .22lr or a custom LW airgun barrel. As LW don’t make a 1:16 twist for Airguns. Is this special made and supplied by someone else etc ?

    Huben have a great product but the marketing and sales pitch is woefully below what we come to expect from Airgun manufacturer’s these days.

    Personally, there is no way I am spending $310 on a cutting device and sizer for bullets which may or may not work depending on what barrel is supplied with the K1 you ordered from supplier XYZ.

    IF / WHEN I order one, then I want to know which version it is, which barrel it has and what bullet/pellet should I be ordering or moulding/swaging myself etc.

    Huben, get a grip and sort your company/product out for early 2018 otherwise you run the risk of failing before you properly enter the Airgun world.
