30-06 Springfield Cartridge:
 The 30-06 Springfield centerfire rifle cartridge is a .30" caliber, rimless, bottleneck cartridge case design and reloadable.

30-06 Springfield History:
The very popular 30-06 Springfield was created by the U.S. military and commissioned into use in 1906. The 30-06 springfield's official military name "Caliber.30, Model 1906, Mark 1". The 30-06 was used in the bolt-action M1903 Springfield rifle, the bolt-action M1917 Enfield rifle, the semi-automatic M1 Garand rifle and machine guns. Instantly the 30-06 cartridge was adopted into civilian use for sporting purposes and rapidly expanded into the world wide shooting community and in which it was accepted with open arms. The 30-06 is one of the most widely accepted cartridges in the world. The reason for such popularity is the availability of bullets which range in weight from 100 grains to 220 grains. The 30-06 brass cartridge case lends itself well to be altered into other calibers and cartridges, the list is long and most of the cartridges that were developed are some of the best we have today.

 The 30-06 with the power it offers down range will recoil somewhat to the shooters shoulder with heavier bullets in the 180 grain range, the recoil is at the peak of what most shooters will tolerate. However with achievements of the ammunition manufacturers in the past ten years, recoil has been reduced dramatically and this has moved the 30-06 cartridge into a stand alone position of the most versatile rifle cartridge in all of North American hunting. With lighter weight bullets suited for varmints and heavy bullets suited for large bears, elk and moose, the 30-06 Springfield is capable of handling all of the game animals in North America.

 While those that handload their own ammunition for the 30-06 have been nearly duplicating 300 H&H Magnum ballistics for years with their 30-06 handloads, the ammunition manufacturers have picked up the pace with high performance loads for the 30-06 as well. Remington's 55-grain Accelerator load with its 55-grain saboted bullet at 4080 fps for the 30-06 is quite an achievement, Hornady's Superformance loadings offer standard loadings with an average of 200 feet per second velocity gains over standard 30-06 loads of equal bullet weights with the use of specialized gun powders.

External Ballistics:
 External ballistics pertains to bullet velocity, energy and trajectory down-range. Bullet trajectory is the flight path of the bullet relative to some known and fixed points.

Bullet Trajectory And Sighting Plane:
 1. Point blank range when sighting in a rifle is the first point at which the line of sight intersects with the bullets path in the bullets trajectory.
 2. Mid-range rise when sighting in a rifle is the highest point in the bullets trajectory between the point blank range and true zero.
 3. True zero when sighting in a rifle is the second point at which the line of sight intersects with the bullets path in the bullets trajectory.
 4. Maximum point blank range when sighting in a rifle is the height of the mid-range rise and the bullet drop beyond true zero, both are equal in measure.

30-06 Springfield Rifles:
 Common barrel lengths for the 30-06 Springfield are;
20, 22", 24" and 26", all of which will show a variance in the ballistics of the 30-06 Springfield.
 Variables such as riflescope choices, riflescope mounts and properly mounting your riflescope affect the line of sight above the bore centerline, which contribute to ballistic variances as well.
 To achieve maximum accuracy from your 30-06 Springfield rifle for proper ballistic evaluation you need to, break-in your rifle barrel and then accurately sight-in your rifle.

Rifle Sight Height And Bullet Trajectory:
 To properly sight-in a hunting rifle a person needs to know a little bit about their scope mount height of their rifle as this affects the sight plane that intersects with the bullet's trajectory.
Rifle Sight Height to Bore Center Line:
Open Sights = 1 inch sight height.
Rifle Scope Center Line to Bore Center Line:
Standard 1 Inch Diameter Scope Tube.
Low Scope Mount And Rings = 1.5 inch sight height.
Medium Scope Mount And Rings = 1.8 inch sight height.
High Scope Mount And Rings = 2.0 inch sight height.

Rifle Barrel Length, Bullet Velocity And Energy:
 Bullet velocity readings are generally taken from a rifle barrel length of 24 inches and using the following formula the bullets energy is determined; velocity x velocity x bullet weight = _ divided by 450,340 = bullet kinetic energy in foot pounds. If your rifle barrel length is not 24 inches then you have to recalculate the bullet velocity and bullet energy, bullet velocity deviation by barrel length;
Rifle Barrel Length Shorter Than 24 Inch You Subtract Velocity.
Rifle Barrel Length Longer Than 24 Inch You Add Velocity.
2,500 to 3,000 feet per second advertised velocity, adjust at 20 feet per second per inch from standard of 24 inch rifle barrel.
3,000 to 3,500 feet per second advertised velocity, adjust at 30 feet per second per inch from standard of 24 inch rifle barrel.
3,500 to 4,000 feet per second advertised velocity, adjust at 40 feet per second per inch from standard of 24 inch rifle barrel.

Bullet Ballistic Coefficient:
 The bullet ballistic coefficient, higher B.C.s mean flatter trajectories and higher retained energy down-range on target. A ballistic coefficient is the measure of a bullet's relative ability to overcome air resistance. Each bullet is assigned a numerical value expressing this efficiency. Ballistic coefficient calculations combine both shape and sectional density factors.

Bullet Energy (Terminal Ballistics):
 Before the bullet is down-range and on target, you have to know whether the bullet will have enough energy retention to cleanly harvest the animal. A bullet's kinetic energy is measured in foot pounds, and this is a proxy for what's generally termed stopping-power. The higher a bullet's energy at the point of impact, the greater its stopping-power.

Target Size (External Ballistics):
 Just as important is the size of target that a game animal that your hunting presents to you, typically standing broadside, exposing heart and lung area. Below are several hunting ballistics and sight-in charts for 30-06 Springfield ammunition that categorize this ammunition to its practical use on various game animals for hunting at various distances.

For this size animal, I prefer 2,000 foot pounds of bullet energy.
