Omlouvám se ale bohužel jsem musel zakázat psaní anonymům, protože nám tu nějaký sabotér vložil "hack" kvůli kterému nešlo přispívat nikomu. Nevím jestli to pomůže, ale snad nad tímto darebákem budeme mít větší kontrolu.
Srdečně zveme do tohoto klubu všechny, kteří se zajímají o zbraně, střelbu a všechno, co s tím souvisí a chtějí si o tom všem v přátelské atmosféře povídat, poradit druhým, nebo se naopak chtěji zeptat na radu.

Kdo chce vystupovat anonymně (tj. bez registrace na Lopuchu), musí si vymyslet nějaké jméno nebo přezdívku a psát ho do každého svého anonymního příspěvku.

Každého přece musíme v diskusi nějak oslovovat, aby bylo jasné, kdo na koho reaguje. Kdybychom měli odpovídat několika bezejmenným anonymům najednou, byla by diskuse značně nepřehledná. Takže, kdo neuvede jméno či přezdívku, ten jako by nebyl.

    Cobray Pocket Pal Revolver: Deep Dive, Detail Strip, Inner Workings. Twin-barrel, twin-caliber gun!

    Who doesn't want to see inside of the very unique and interesting Cobray Pocket Pal twin-barrel, twin-caliber "revolver?" It shoots .22 LR out of one cylinder and barrel, and .380 ACP out of the other cylinder and barrel. 5 rounds and 3 rounds, respectively. How odd!

    In this video the Pocket Pal is detail stripped, and its function is explained. Can't say I've seen anything else quite like it! It sure doesn't look like a revolver when it's closed up and ready to shoot. It's actually pretty comfortable in the hand and points naturally. Recoil in either caliber is extremely controllable. Accuracy stinks. Trigger pull is maybe 15 lbs or so... very heavy and very long, and not particularly smooth, either. There you have it... not really a review and no shooting in this video, but I think the inner workings are interesting!

    I suppose it would be effective at contact distances, but I have it as a novelty, really. If nothing else, it's a fun gun with a very unique design!

    East Germany's Secret Walther Clone: The Pistole 1001-0



    When the Allies occupied German at the end of World War Two, the Walther factory at Zella Mehlis was initially garrisoned by American soldiers (who did a pretty thorough job liberating all the guns they could find there) but eventually ended up in the Soviet occupation zone (and later East Germany). This was in Suhl, a major area of weapons production, and the DDR set up a large factory complex of its own there called the Ernst Thalmann Werke (named after a German communist martyr).

    In 1947 a team of engineers started to rebuild the production line for the Walther PP from the tooling and drawings that remained at the Walther plant. The government wants to use pistol for both military, police, and security service. The factory code was 1001, and the pistol was given the designation 1001-0. It took several years to fully reconstruct the production facilities, and once it did production ran from 1953 until 1957 (when the Makarov took over), with about 20,000 produced overall.

    Venezuelan FN49: The First FN49 Contract

    Venezuela was the First Nation to purchase the FN-49 rifle, before even the Belgian military. In fact, the Venezuelan contract was signed in 1948, before the "FN-49" designation was even in place. Venezuela bought a total of 8,012 rifles in two batches - 4,000 rifles plus 12 cutaway training examples delivered in 1949 and a further 4,000 more rifles delivered in June 1951. All of them included the integral muzzle brake and scope mounting cuts, although no scopes were ever procured. They were all semiautomatic models.

    Some of the rifles were issued and used, but some appear to have remained in depots their entire life. Venezuela was also an early adopter of the FAL, and the FN-49 was only used for a short time. In 1966, all of them (or virtually all) were sold as surplus to InterArms, and brought onto the US collector market.

    Neznáte někdo náhodou „Jardu Pulicara“, měl by být odborník (mj.) na vnitřní balistiku? Kdosi mne na něj odkázal, že prý „kontakt najdete na FB“, tam já v životě nebyl a bohdá nebudu... Kdybyste měl někdo na něj civilisovaný kontakt jako třeba e-mail, budu vděčný za odkaz. Dík.

    Ale jdu sem původně s jiným dotázkem: potřebuji testovat powder dispenser; nejde o prachování samotné, ale o řídicí a komunikační protokol toho zařízení.

    Nechce se mi úplně pořád bůhvíkolikrát dokola točit a zase vracet skutečný prach. Naprázdno to ale taky nejde, potřebuji něco, co když dispenser sype na misku, váha roste.

    Co byste doporučili za jiný (inertní) materiál, který by měl fysikální vlastnosti co nejbližší skutečným prachům, samozřejmě dispenseru nijak neublíží, bude se z něj snadno vyndavat, a byl by pro takové testování vhodný? Dík!

    To bohužel bezpochyby. Maxima jsem ještě nikdy nikde na prodej neviděl; občas se ale objeví Gatling, a prasecky drahé bývají dokonce i moderní kopie (jež jsou v USA legální, u nás by asi nebyly) :(

    Argentine Brass Maxim: A Machine Gun of the Steampunk Age

    The Maxim Gun was the first successful true machine gun, and it became extremely popular worldwide. Maxim sent his first two working models to Enfield for testing in 1887, and by 1889 he had what he termed the "World Standard" model. No two contracts were quite identical, as the gun was constantly being tweaked and improved, but the 200 guns sold to Argentina in 1895 (50), 1898 (130) and 1902 (20) are a great time capsule into the configuration of the early Maxim guns in military service.

    The Argentine Maxims had gorgeous brass jackets, along with ball grips, triggers, feed blocks, and fusee spring covers. The have the early 1889 pattern lock, complete with a walnut roller to assist belt feeding into the action. These guns were in Argentine military service until 1929 (which included a retrofit at DWM in 1909 to use the new Spitzer 7.65mm Mauser cartridge). They then passed into police use until 1956, and 91 were sold to Sam Cummings of InterArms in 1960. Of those, 8 were exported out of the US, 28 went to government agencies and museums, and the remaining 55 were sold onto the US collector market. They are the single largest group of early Maxims in the country today, and make fantastic collectors' pieces.

    Hotchkiss Portative: Clunky But Durable

    The Portative was an attempt by the Hotchkiss company to make a light machine gun companion to their heavy model (which had found significant commercial success). The Portative used the same feed strips, albeit loaded upside down, and the same gas piston operation, but a very different locking system. Instead of a tiling locking block the Portative had a "fermeture nut" that rotated to lock onto the bolt with three sets of interrupted thread locking lugs. In addition, many of the traditionally internal parts were mounted externally on the Portative, and it was quite the awkward gun to use.

    The Portative was adopted by the American Army as the Model 1909 Benet-Mercié, and by the British early in World War One as a cavalry and tank-mounted gun. The remainder of Portative contracts were relatively small from second-tier military forces, including several South American countries.

    Ballard .41 Rimfire Derringer: An Old West Boot Gun

    Charles H. Ballard is much better known for his single shot rifle design, but he also designed, patented, and produced a .41 rimfire caliber derringer. These were popular concealed weapons during the 19th century, and remain in production even today (though no longer in .41 rimfire...). Production began circa 1870, and a few thousand of Ballard's derringers were made.

    FN Model 30: The First Belgian BAR

    FN played a role in the production of Polish wz.28 BARs, and in the process obtained a copy of the technical package for the weapon, and converted it to metric measurements. Under the supervision of Dieudonne Saive, this was used as the basis for FN's own BAR production, called the Modelé 30. Production was done with a license from Colt, who owned the rights to Browning's patents on the BAR.

    The Model 30 was basically a Colt R75 (Model 1925), but incorporated a few improvements. Most significantly, the male and female parts of the gas system were swapped, which prevented carbon from building up and eventually jamming the gas piston. In addition, the bolt removal latch was improved form he US pattern, and the Polish wz.28 style rear sight was used. Lastly, a rate-reduction mechanism oil the fire control group gave the gun "slow" and "fast" settings, of roughly 350rpm and 600 rpm instead of the traditional semi and full auto settings.

    Production began in 7.65mm, and the Belgian Army adopted the weapon, taking deliveries form 1930 until occupation in 1940. The Model 30 was also made in 8mm Mauser, and exported to China and Ethiopia. The design was fairly quickly supplanted in 1932 by the FN Modelé D, which added a quick-change barrel mechanism to the design, and this pattern sold more widely.

    The Gun Science Says Can't Work: Madsen LMG Mechanics


    The Madsen LMG is generally considered an extremely complex and confusing system - but is it really? Today we are taking one apart to see just how it actually works. Because in fact, it's a very unusual system, but not really any more complicated than any other easy self-loading action.

    Aha! To je zajímavá informace!
