The most important reason to select a larger bullet is energy at the target, which improves “terminal ballistics.” Basically, if you want better expansion and penetration you will likely want to choose a heavier bullet. A 180-grain bullet from a .300 Weatherby Magnum exits the muzzle of a 26-inch barrel about 1 1/4 milliseconds after it starts to move. Thanks for using the external ballistic calculator from that accurately details all aspects of the bullets trajectory the millisecond it leaves the guns barrel. The point is that even when you purchase a given firearm to shoot a specific cartridge, you still have options for bullet size.

For example, 9mm rounds may be listed as “115 gr FMJ.” This tells us that the cartridge is loaded with full metal jacket bullets that weigh 115 grains. All the ballistics from all manufacturers, finally... in one place. hardness of a cast bullet and the velocity at which said bullet can be safely propelled. At 200 yards there is perhaps 4 to 5 inches of bullet drop. But, the implications on energy into the target are significant. A typical question might be how much does a .308 bullet drop at the 500 yard distance. So it would be fair to say that around 900 yards as an average is the effective range of the .308 Winchester, where the rounds can reliably be placed on the target. (Both expansion and penetration are affected by bullet shape, material, and other factors as well, but weight plays a role.). Developed form the military, Winchester brought the .308 round onto the market in 1952. We know it requires more energy to move a heavier bullet than a lighter bullet, right? The five shot average muzzle velocity for the heavier 147 grain bullet was just under 940 feet per second. Here’s what we can say: a lighter bullet generally has greater speed, which means it can often maintain a straighter trajectory at a greater distance.

Effective range is always a tricky question to answer as it’s dependent on so many factors. Many calibers has a standard bullet weight, such as the .223 Remington with a 55-grain bullet. Velocity is classified as low (<1000 fps), medium (1000 to 2000 fps), and high (>2000 fps).

If you do not have a Shooting Chronograph, I strongly suggest you purchase one. 0000017013 00000 n

For such scenarios, Few suggests that for the specific measure (expenses) we reverse the direction in which the bar extends as well as the quantitative scale. 0000005570 00000 n Your information will never be shared and you can unsubscribe with one click at anytime. The bullet is on its way.

It will a produce a line graph showing the bullet drop and flight path of the bullet. I want this to be the best ballistic trajectory calculator out there.

0000029077 00000 n For example, the 9mm Luger is most commonly found with 115-grain, so this is likely your best starting point. In data visualization, we are often faced with situations where we have to feature a single measure, compare it to a target value and also indicate if it is good, bad or ugly, and all this in a limited space. xref Nevertheless, the data table shows consistency with the pictorial graph shown for the trajectory.
