    On here we usually talk about bullet weights in grains. When he says 37 g, he means grams not grains. A 37 grain bullet is only 0.085 ounces but a 37 gram bullet weighs 1.3 ounces. Huge difference. Just trying to clarify.

    What you are attempting has already been achieved, albeit on a much larger scale, in the main guns used on several main battle tanks in use today. Attempting to 'scale down' this technology is admirable but I seen no existing commercial market to justify the time and expense involved.

    You have clearly noticed: “zoom out”. That's right, for a good stabilization of the feathered projectile in flight or is increased the length of him , where there are still problems with the separation of the metal pallet ..

    ... or increases the area of the stabilizing plates . That's what I did in my design, it turned out compact and efficient. So what? Do you think hunters, athletes and tourists in nature will not want to have a good product?

    If you raised the topic of weapons, I will continue. Have you ever shot long distances from a rifled barrel? After each shot, the shooters will advise you to cool the barrel for 3-6 minutes, otherwise your activity will become useless. As a rule, automatic artillery guns with a caliber of 25-45mm with a rifled barrel, and after 50 — 60 shots in the automatic mode doesn't get to a tank target on 500 m any more. Here, the smooth trunk and compact projectile are a big plus.

    So what can you tell us rifled versus smooth bore with your product?

    Velocity improvements?
    Distance comparisons?
    Maximum range?
    Consumer cost?

    And finally, why would anyone want or need your product?

    I made the structure well stable in flight, and what pressure to create in the barrel (the amount of powder charge) for a shot depends on the thickness of the barrel and the steel grade from which it is made. The initial velocity of the projectile depends on these values, respectively, and the distance in meters. Cartridge drawing IWS 2000

    In the beginning I already wrote that there is an Austrian sniper gun of the company "Steyr", caliber 15.2 mm. I would make shells for this caliber. There is a barrel, there are shells for it, or maybe the forum participants had such a gun lying around somewhere?
    Anyone connected with CNC machines will answer this question about the cost of the product. Let him see the picture, the approximate dimensions are clear there. Prices are different everywhere, but not expensive anyway. And if you order all this from Chinese comrades, the price will delight you even more.
    Of course, there are still minor secrets of charging a cartridge, but this is not for lighting in public places.

    Q. Do you think hunters, athletes and tourists in nature will not want to have a good product?

    A. I do not believe this product will strike the fancy of, nor do I believe it is fitting for, any of the above.

    Q. Have you ever shot long distances from a rifled barrel?

    A. I have, and do, regularly. 'Long range' (1000 meters, or further) is not a rapid fire proposition.


    Your projectile may be of some interest to the militaries of several countries.

    Although interesting (?), I feel you are barking up the wrong tree.

    After the last successful tests, I searched the Internet for similar existing samples. Grenade-gun Barrett XM109 is very good in terms of the declared parameters, but he never became a serial weapon and was not accepted into service in the army. I began to analyze this sample. One of the reasons for culling is that the recoil from the shot is very large, which is nosurprising when the shell is heavy and unwound in a rifled barrel.[Only registered and activated users can see links. ]

    XM109 acquired all the diseases of the rifled barrel, the first shot is accurate, subsequent when cooling the barrel, if you want accuracy. Moreover, the shooter gets hit by a horse's hoof in the shoulder in the form of recoil from the shot. Let me remind you that it was called Objective Sniper Weapon, today it is known as Anti-Material Payload Rifle.

    To have in the army weapons for infantry at 1.5 - 2 km that affects all lightly armored targets, up to a medium-armored tank, as well as clearing territories, is probably the dream of many countries. I know that corporations from many countries are working on this topic, and China too is not lagging behind: [Only registered and activated users can see links. ]

    If you equip the system like an M1 with a smooth barrel and take a new-design shell, the indicators will improve dramatically. Caliber - 30mm, the shell is equipped with a tracer compound visible in ultra violet light. Another big plus is shells with a cumulative charge, which when executed in a smooth barrel gives a greater effect. The cumulative effect is the same when reaching the goal, and at 200m, and 2 km. The shooter no gets hit by a horse's hoof in the shoulder in the form of recoil from the shot. The smooth barrel works softer.
    Who got acquainted the patent, there is also a rifled version for such medium (25 - 40 mm) calibers. The projectile on the runners in the barrel receives angular velocity (rotation). video below:
