CHECK OUT SOME PARAGRAPHS FROM MY BOOK.

HERE ARE A FEW PARAGRAPHS FROM MY BOOK:
EXCERPT 1:  
     There are many skills you can learn to help you become very good at hunting with a rifle.  You have to practice these skills, which I’ll discuss in detail in this chapter.  You have to practice shooting your rifle until everything becomes a reaction………. you don’t think, you just Do It.  Practice until ice flows in your veins and never lose your focus. You'll have to learn to snap shoot if you hunt the Jack Fir of the Pacific Northwest.

EXCERPT 2:
     First, you must consider your bullet’s B.C. and S.D.  As I’ve mentioned before in this book, the bullet’s B.C. is its form factor in relationship to its length and drag. . . .  The bullet’s S.D. is its weight (in grains) in relationship to its diameter (caliber), divided by itself, which determines the mass of the bullet's S.D.  Thus, the formula for S.D (for a 175 gr bullet) is: 175÷7000÷.284 (caliber)÷.284 = .309958341, which is rounded up to .310.    Second, you must consider the wind.  Wind can and will blow all bullets off course, more and more as the range gets longer and longer.  Third, uphill and downhill shots will be affected depending on the angle in degrees.

      A bullet’s B.C. is the most important factor in what determines your rifle’s effective range.  An example is that a round nose bullet (it has low B.C.) will not hold its velocity or have the effective range that a bullet of the same caliber and weight with a high B.C., will have.  This is because . . . . .

EXCERPT 3:
     In the nano second that it takes for the primer to explode, pressure starts to build within the chamber.  When the powder in the case explodes, pressure takes a dramatic jump.  The case then expands within the chamber walls.  The violent explosion of powder rips the bullet from the case and shoots it down the barrel.  This is interior ballistics.  The firing pin has struck the primer, and the primer has exploded, sending fire through the flash hole, igniting the powder in the case.  The case powder explodes.  Pressure in the chamber as the powder explodes is so dramatic that it slams the case back against the bolt face, taking up the head space, and expanding in the case to fill the chamber, which stretches the case neck forward.
