9mm how far can it shoot

It's from NASA, so it has to be good, right? It doesn't really change the max height. Maybe the problem is with the drag coefficient. Here is a plot of the drag coefficient C as a function of speed. It looks "blocky" because I am just using data from that wikipedia table.

But maybe this is the problem. Actually, maybe the problem is that the drag coefficient table doesn't work very well at low very low speeds. Now that I think about it, the MythBuster's said they simulated the. Who knows how long it took. They did know the time for the 9mm bullets, they heard them hit the ground. Let me run my calculations with the 9mm info. Using mass of 7.

Which seems much closer to what they MythBusters had. And I just realized another mistake on the. I calculated the area with the diameter instead of the radius. That is better. I hope this is a lesson to all you kids out there. Mind your factor of 2's. Of course if I get this to work, now my terminal velocity is much higher than what they measured. Oh well. My next step is to look at the final speed of the bullet if you shoot it not straight up.

I suspect this is the how people get killed. Here is what Adam said about the bullets: A. The plan. Rhett Allain is an associate professor of physics at Southeastern Louisiana University.

Also, consider that there is no limit for any safe and out of bounds area. I mean that fluke shots are still lethal although the target is far away and the shot unintended. Other factors that make a shot lethal include, point of entry, impact angle, and area of entry.

There are a whole lot of things that could make a shot lethal or not. Sometimes at close range, a bullet may pass through flesh missing vital organs and therefore inflicting only flesh wounds instead of fatality.

Therefore, despite all the arguments of the lethal range, the first rule of gun handling is to ensure that firearms are always pointed downwards.

Always practice safe use to ensure your safety and the safety of others around you. There are some variables that we must consider before we give a blanket answer. First, is based on the type of 9mm round. Some ammo is loaded at a higher pressure and will leave the gun faster than others. Other bullet shapes will cause less drag than others. Also, the type of firearm will determine the velocity of a bullet. Longer barrels allow the bullet to reach higher initial velocities than a short barrel handgun.

If you already know the velocity at which the bullet will fall, then all we need to do is calculate how fast it travels when it leaves the barrel. For example, a standard grain bullet leaves the 4.

When calculating velocity, it is essential to know that all guns fire bullets at a small upward angle. For handguns, the distance is about 25 yards. When you fire a bullet it travels through a medium. In this case it is air. The bullet slows down because of the friction caused by the medium. It is what we refer to as drag. Drag varies with the ballistic coefficient of the bullet as this is determined by the shape of the bullet. A 9mm handgun bullet, having a round, as opposed to a spire nose will not have a very good ballistic coefficient.

Everywhere you go, wisdom dictates that shot placement is more important than the caliber you use to shoot. Small rounds may not penetrate bones or breastplate when hunting. Caliber does matter. However, the emphasis on shot placement is to remind you that when you miss it is the same as shooting a zero caliber bullet. Therefore, shot placement is not necessarily king but rather it is the proficiency of the firearm you will use.

It is why the cost of the ammo matters. For example, if a 9mm costs about 14 cents a round. And a. There is only a 5 cent difference. Eventually, it all adds up though.

Regardless of your budget, if you shoot the 9mm you will get more training for your money, and therefore become more proficient with your gun. In effect, you will have a better-shot placement. Because it is a heavy round, the. I see the debate of how far out to put the target almost every time I go to a range during public hours. Six feet is about as close as you can get to a hanging paper target without the muzzle blast from normal self-defense rounds moving the paper too much.

Drilling holes flat footed at the six- to foot range is an indication that you can align the muzzle properly and press the trigger without disturbing muzzle alignment. Any flyers or problems that show up here will be magnified with distance, stress, speed, and movement. Grip, stance, breathing, and follow-through all help, but muzzle alignment and trigger press are the only two things that are vital.

Work that you do here gets incredibly high leverage results and will impact all shooting that you do, regardless of the gun, distance, or speed. But the goal should always be to make precise hits faster, fast strings of fire more accurate, and do it under more and more challenging conditions.

As we cover in Praxis , this will optimize learning speed and give you the most bang-for-the-buck for your training time and training dollars.
