  • Diana 75 zerlegen?????

    Hallo Freunde,

    habe ein Diana 75 erstanden aber meine anfängliche Freude währte nicht lange.
    Zwar war das System von einem Waffensammler mit reichlich Öl in eine Tüte verpackt worden und sieht nun aus wie aus dem Laden aber es schießt nicht :cry: .
    Statt Druck kommen nur Lederbrössel aus dem Lauf.
    Nun klar was da kaputt ist.
    Jetzt meine Frage:
    Durch das Doppelkolbenprinzip bin ich nun verunsichert was das Demontieren angeht.
    Wer von euch hat sie schonmal auseinandergenommen und kann mir ein paar Tips geben? :huldige:
    Ich habe bereits das Diana 35 zerlegt und wieder zusammengebaut und bin handwerklich versiert.

  • Wir teilen uns ein Vo-Messgerät

    Hallo Freunde,

    vielleicht geht es euch ja auch so wie mir:
    Ich würde allzugerne mal die Vo meiner div. Bleipuster nachmessen finde die Infestition in ein entsprechendes Gerät für die paar mal messen aber zu hoch.
    Gut, dieses klein Vo-Meter zum an die Mündung basteln ist nicht so wahnsinnig teuer, soll aber nicht sonderlich zuverlässig sein.
    Nun gibt es bei Frankonia ein Gerät zum "Durchschissen" für glaube ich 289 DM.
    Wenn das was taugt könnte ich mir vorstellen, dass sich vielleicht 10 von uns zusammen tun um ein solches gemeinsam zu erwerben und wir schicken es dann Wochenweise im Ring rum, bis wir uns gemeinsam entschliessen es wieder zu verkaufen oder weiter zu verleihen.
    Vielleicht ist das jetzt etwas blauäugig von mir, da ich keinen von euch perönlich kenne aber in Zeiten von eBay hat man ja gelernt wieder eine gehörige Portion Vertrauensvorschuss zu investieren.

    Also was haltet ihr von dem Vorschlag oder gibt es dieses Vo-Meter-Shearing ( auserhalb der Vereine) schon?
    Bin auch für andere Ideen zu haben.

  • Kleiner Test der Durchschlagskraft

    oh je,

    was ist nur aus dem thread geworden? :cc
    Mein Vorschlag war durchaus ernst gemeint!
    Getränkedosen eignen sich m.M. nicht da sie viel zu dünnwandig sind.
    Katzendosen deshalb, weil sie egal von welchem Hersteller die gleiche Wandstärke haben.
    Vielleicht hat ja jemand Langeweile und beschiesst mal eine Reihe!

  • aufgemotztes Crosman 1077

    So ein Zufall!!!

    ich habe soeben vom Umbauer der Crosman und dem rührigen FTS Pionier Volker Blüm die Beschreibung des Umbaues erhalten.

    VB-CUSTOM CO2-POWERED ”RATHUNTER RIFLE”

    (CROSMAN 1077 Repeat AirÒ-based CO2 Pellet Rifle)

    Caliber: 0.177 pellet.

    Magazine: rotating cylinder clip 12 shots.

    Action mode: semi-automatic action, trigger repeater (as fast as trigger can be pulled).

    Power Plant: 12 g CO2 bulb.

    Stock: original with the following modifications: lightly sand-blasted, butt filled with lead pellets in epoxide resin, additional length-adjustable hard rubber buttplate fixed with stainless steel cylinders. Foreend, pistol grip and left butt piece covered with special micro-checkered neoprene rubber.

    Further modifications: trigger and magazine-moving parts honed for ultra-smooth action (trigger pull weight approx. 900 g), CO2 tank cover screw modified as stainless steel receiver for MINI MAGLITEÒ AA. (Caution: in Germany: it is prohibited by law to mount any source of target illumination on any gun; violations may be charged with heavy penalty.) For utilization within Germany use recommended PVC/lead dummy with the same weight as the MINI MAGLITEÒ. The rifle may be equipped with an easy-to-install PVC bar at the stock foreend to “guide” a hand-held MINI MAG-LITEÒ. Original iron sights removed. Adjustable stainless steel muzzle weight. Two internal TEFLONÒ “floating” barrel supports for increased barrel stability. The magazine bottom carries a split plastic weight to allow faster magazine exchange or removal.

    Muzzle energy: approx. 9 J in the U. S. (in Germany acc to firearms legislation 7.5 J).

    Muzzle velocity: 182 m/sec with 7.5 J version (CROSMAN PREMIERÒ 7,9 grs).

    Sight: 6 x 32 GD6321 MINIÒ pointed crosshair.

    Overall length: 105 cm (max buttplate adjust).

    Weight: 3.6 kg.

    Accuracy: less than 1 inch diameter for group of 12 shots 20 m distance (fixed rifle, U.S. version).

    Description: The VB CUSTOM RATHUNTER CO2 rifle is based on the extremely low-priced (approx. U. S. $ 90.-) CROSMAN 1077 Repeat AirÒ CO2-powered rifle. It is especially designed for pest control under difficult light conditions or in darkness. The original plastic stock backpiece is filled with (used) lead pellets embedded in epoxide resin. The original buttplate is fitted with 2 tubular stainless steel receivers in which the stainless steel carriers of the 28 mm hard rubber buttplate are inserted. The latter may be adjusted continuously to distances from 0 to 5 cm. The whole stock is lightly sandblasted and the forepiece, the pistol grip and a part of the left side (for right-handed shooters) of the butt are covered with physiological inert neoprene rubber sheets with micro-checkered surface to allow a sure grip. The cap screw of the CO2 tank is modified as a receiver for an AA MINI MAGLITEÒ which provides a good target illumination on distances up to 10 to 12 m which is the maximum to be used in pest control with low-powered air- or CO2-rifles. The latest development is designed to carry a SURE FIREÒ Combat flashlight. (ATTENTION: it must be pointed out clearly that German firearm legislation strictly prohibits the mechanical combination of any target-illumination light source with any type of gun.) So, for utilization within Germany a weight-identical MINI-MAGLITEÒ dummy (plastic with lead core) may be inserted. The lamp then can be used by pressing it to the rubber -covered left stock foreend side with the thumb of the left hand of a right-handed shooter. In this case it is recommended to fix a PVC adjustment bar with the short black screws into pre-drilled holes near the barrel. This is a legal procedure for pest control and the lamp direction is guided to the target without a mechanical coupling of gun and light source.) The original barrel housed in a relatively thin-walled steel tube was supported at the muzzle by a plastic cylinder carrying the front sight. This was removed and the inner barrel now is supported by 2 ”floating” TEFLONÒ cylinders, i. e. these do not fit exactly into the diameter of the barrel housing. One of those reaches under the barrel band and the other is under the muzzle weight. Both are about 0.5 hundreds of an inch smaller than the barrel housing diameter and they are fixed each with an about 0.01 inch tolerance by 2 removable steel pins inserted into the barrel housing and which are held in place by a PVC support block inserted into the stock foreend and the muzzle weight, resp.. The latter is made of stainless steel and adjusted in a way to keep the rifle in a perfect balance when held at the trigger guard. It may be modified to fit individual demands of the shooter (some like a heavier muzzle end). The rifle was tested fixed in a “shooting machine” and gave excellent 12 shot-groupings of less than 2,5 cm (1 inch) at a distance of 20 m at an ambient temperature of 20°C with the U.S. version. Lower temperatures result in a altered vertical trajectory shooting about a little bit more than 1 inch (about 3 cm) lower at 12°C. Ultra-rapid fire of a whole magazine will also result in a drastically altered bullet trajectory. Finally, the mounted 6x32 GD6321 MINIÒ pointed crosshair scope was adjusted to 12 m which corresponds to the adequate hunting distance for, e. g., rats. The 6-fold magnification of the scope is the highest which can be recommended and should be used only by experienced shooters. Beginners should start with a 3-fold magnification. In case of using no light source a larger scope diameter (40 - 50 mm) should be chosen for pest control under weak light conditions. Variable scopes are not recommended for the close distances because they may create difficulties with parallax compensation. One CO2 bulb is good for approx. 3 magazines (36 shots). Larger CO2 and compressed air containers replacing the lamp adapter are commercially available (German and British providers; must be imported to the U.S.) but do not pay off in my experience. The customized VB RATHUNTER RIFLE is not commercially available but advice can be provided how to make or where to obtain muzzle weight and lamp receiver and how to construct the adjustable butt plate.. Tuning of the trigger mechanism should only be done by an experienced gunsmith (addresses available in the U.S. and Germany). Even when done totally by oneself the VB-RATHUNTER modifications are not cheap (approx. U.S. 200.- for the MAGLITEÒ version, the SURE-FIRE flashlight including mount demands additionally U.S.$ 110.-) but result in a totally novel and exciting rifle with an excellent performance for the designated purpose. It is also great for 5 shot-rapid fire silhouette shooting on 15 or 20 m distance (allow 30 seconds for a 5 target series or take 15 seconds for ram, 20 seconds for pig, 25 for turkey and 30 seconds for chicken). This procedure is especially great for Field Target Club competitions to increase the challenge and fun!

    Special remarks for pest control: The ”Rathunter Rifle” was developed especially by reasons of an intolerable high and aggressive rat population in my home area in Florida. Some pests, especially rats, are more intelligent than the controller might believe. They recognize rapidly the connection between the death of a species companion and a human being carrying a rifle and will not longer accept baits if they recognize the latter. The only way for successful hunting is therefore to offer baits at a suitable place short before dawn and to hide and to wait with the aimed rifle with patience until they appear to take them. Then, switch on the flashlight and the animals mostly ”freeze” in the light beam. The SURE FIREÒ is the optimal solution for this procedure. Then immediately start rapid fire.


    VB’s permanent advice:

    EVER FOLLOW STRICTLY THE SAFETY RULES WHEN TOUCHING AND USING A GUN!! NOBODY IS ABLE TO BRING A BULLET BACK WHEN ONCE FIRED! EVEN A LOW-POWERED AIRGUN IS NO TOY AND MAY CAUSE SERIOUS INJURY!

  • Kleiner Test der Durchschlagskraft

    Hi Gemeinde,

    ich habe zum vergleich meiner Gewehre einen einfachen Test entwickelt:

    Man nehme drei Katzenfutterdosen ( 425g) und stelle sie hintereinander auf eine Fläche ( ich habe dazu einen Unterstellbock.
    Nun auf 10 m die Dosen mit einem 4,5 mm Flachkopf-Diabolo beschiessen und schauen wie viele Dosenwände gelocht wurden.

    Meine Erfahrung sagt, dass dieser Test fast 100 %-ige Reproduzierbarkeit hat!
    Mein FWB locht immer zwei Wände und beult die nächste Dose gleich weit ein.
    mein Diana locht noch eifriger .

    Probierts aus und postet eure Ergebnisse!

  • ZF auf Matchgewehr FWB c60

    Hi folks,

    ich möchte mein FWB c60 Matchgewehr :n1: mit einem grossen ZF :crazy2: ausrüsten und habe nun einige Fragen an das geneigte Expertenfolk :o: :

    - Gibt es eine Umrüstsatz damit die Ladeklappe nicht gegen das ZF stößt und ein laden damit unmöglich gemacht wird?
    - Ist denn die kurze Prismenschiene nicht zu weut hinten und wenn ja, wie kann man sich dann behelfen?
    Wäre nett wenn jemand dazu was wüsste und ich dieses Wunderwerk an Präzision mal anders nutzen könnte.

  • Entscheidungshilfe !

    Hallo Alfi,

    wieso willst du das HW 77 verkaufen?
    Ich habe gerade ein solches @ 5,5 mm angeboten bekommen.
    Für 160 Euro.
    Wie ist die genauigkeit auf 25 m mit dem Kaliber?

    Wäre nett wenn du dazu was sagen könntest.
