Firearms

With pellet rifles, strongest is not always best. There are rifles such as the Air Force Condor that claim velocities of 1400 FPS from compressed air- others that inject a drop of oil that is burned (dieseling) and get higher velocities (technically those are a firearm, just like a .22 rim fire) HOWEVER-

When a pellet is driven faster than 1100 fps, it is supersonic. It WILL slow down, and drop below the speed of sound. As it drops back through the shock wave at the speed of sound, the pellet will be disturbed, and accuracy will suffer badly.

Yes, there are aftermarket polymer frames available for the Beretta 92FS pistol. These frames can be swapped out for the original metal frame to reduce weight and offer a different feel for the shooter.

That is sort of like asking how many miles per hour does 100 horsepower equal. Ft lbs is energy, and FPS is speed. There IS a formula to calculate the energy (in foot lbs) of a bullet, but to use that, you need to know SPEED in FPS, and WEIGHT (in grains) of the bullet. A 40 grain bullet at 1000 fps is pretty weak. A 400 gr bullet at 1000 fps can drop a moose.

A 9mm Parabellum cartridge loaded with a standard bullet and only a primer will normally not be able to drive the bullet out of the barrel. It will usually lodge in the barrel (this is known as a squib load). If a second normal cartridge is fired behind this, it stands a very good chance of blowing up the gun.

When a gun is fired, the gunpowder ignites and expands rapidly, pushing the bullet out of the barrel in one direction. According to Newton's third law of motion, for every action, there is an equal and opposite reaction. So, when the bullet is pushed out of the barrel, an equal force is applied in the opposite direction, causing the gun to recoil backwards.

Yes, touching a gun can potentially contribute to rusting if the gun is not properly cleaned and maintained afterwards. The oils and salts from skin contact can transfer onto the gun's surface, leading to corrosion over time. It's important to regularly clean and oil your firearm to prevent rust.

There is no one definition of strongest, and NOTHING is "bullet proof"- materials are "bullet resistant". Bullet resistance is defined in regard to specific weapons and ammunition, such as a 9mm handgun, 30-06 rifle firing M2 ball ammo, etc. The "strongest" material I have worked with was lexan polycarbonate, as glazing for the artillery fire adjustment bunker at the Ft. Benning GA range complex. THAT material was 12 layers, each 1.5 inches thick, and intended to protect the occupants of the bunker from repeated hits from 105mm howitzers firing high explosive shells. In some uses, multiple layers of glass are bonded with a high strength plastic.

Rifling marks, the marks etched into a bullet as it travels through a gun's barrel, are to a gun as fingerprints are to a person. To see if a fired round came from a particular gun, the gun is test fired into a pool of water (to stop the bullet without changing its shape) then the marks on the test fired bullet and the bullet in question are compared.

Knowing the trajectory of a bullet points you in the direction of its origination.

There are also some clues that will help you determine from how far a shot was fired, such as approximate speed on impact and the presence of burnt gunpowder.

Because the electron, in effect has no (or very little atomic) mass and is travelling at near light speed, while the molecule of water (H20) has a relatively large atomic mass and is traveling at a much lower velocity (5 to 10 meters per second). This of course, as postulated in the question, relates only to gravitational affect and neglects drag caused by air resistence.

An easy gun bluing formula can be made by mixing copper sulfate, sodium hydroxide, and distilled water in specific proportions. The metal parts are immersed in the solution to create a corrosion-resistant blue-black finish. It's important to follow safety precautions and proper ventilation when working with these chemicals.

DO NOT DO THIS!!!!!!!!!!!!!!!!!!!!!!!!

DANGER, DANGER, DANGER!!!!!!!!!!!!!!!!!!!!!!!!!

You run the risk of causing the brass to weaken.

If you want to clean brass, tumble it with crushed corn cobs or crushed walnut hulls.

it uses a thingy to make it go fasters

It really doesn't speed up reloading. For instance: you have a six-shot revolver and you are tired of loading one cartrige at a time into the cylinder so you get a speed loader that will insert all six cartriges into the cylinder at once...Sure, that was quick but you are ignoring the time it took to load the six cartriges into the speed loader to begin with.

KNO3 (potassium nitrate) is used in gun powder as an oxidizing agent. When gun powder is ignited in a confined space, it rapidly decomposes to release gases that build pressure, propelling a projectile like a bullet out of a firearm. Potassium nitrate supplies oxygen for this reaction to occur.

The value of a Tanfoglio Giuseppe 38 9mm can vary depending on its condition, age, and any additional features. However, a rough estimate would be between $300 to $500 for a used model in good condition. It's always best to have a professional gun appraiser evaluate the firearm for an accurate assessment.

When a bullet is fired, hot gases are released behind the bullet, pushing it forward. According to Newton's third law of motion, for every action, there is an equal and opposite reaction. So, the gun barrel recoils upward due to the equal and opposite reaction to the forward motion of the bullet.

No such thing as an "average gun". The .45 ACP fires a bullet at ABOUT 830 fps. A .220 Swift is over 4000 fps. A .22 pistol and .22 rifle will fire the same ammo, with greatly different velocities.

No, cell towers are not used as weapons. Cell towers are used for transmitting and receiving signals to enable mobile communication. They are not designed or used for any type of weaponization.

Some stainless steel alloys can be slightly magnetic, allowing them to attract magnets. This is often due to the presence of certain elements like iron in the alloy composition. However, stainless steel as a whole is considered non-magnetic and the degree of magnetism can vary based on the specific type of stainless steel used.

There have been more than 2 dozen DIFFERENT 20mm cannon (search 20mm Wikipedia for examples). These used different shells, and had different barrel lengths, and so have different muzzle velocities. The 20mm used by the US and Allies during WW II had a muzzle velocity of ABOUT 2800 feet per second.

About 2900 feet per second, or 1,977 miles per hour.

Bullet diameter of a 9mm is .355; for a 38 it is .357. 38 case is longer. Additionally, a 9mm is designed to be used in a semi-automatic pistol, and a .38 is designed to be used in a revolver, although, there are a couple of revolvers that will chamber 9mm.

Improving the accuracy of observations can be achieved by increasing sample size, using precise measurement tools, minimizing biases in data collection, and conducting repeated measurements for validation. Through these methods, the reliability and credibility of observations can be enhanced to provide more accurate results.

The M1 Carbine is a lightweight semi-automatic rifle used by the United States military during World War II and the Korean War. It has a distinctive profile with a short barrel, wooden stock, and a curved magazine that holds 15-30 rounds of .30 caliber ammunition. The overall length is about 36 inches and it weighs around 5 pounds without ammunition.

There are environmentally friendly explosives, such as green explosives that are designed to minimize environmental impact during detonation. One example is the use of ammonium nitrate-based explosives, which can be formulated to reduce toxic emissions and residue. However, all explosives have the potential to harm the environment if not properly handled, used, and disposed of.
