Writing as B.B. Pelletier
This report covers:
- Today’s discussion
- Round balls
- Conical bullets
- Smokeless powder
- A big point
- Round balls — again
- The bottom line
I’ve taken 11 months to return to this subject of ballistic coefficients (BC). That was in spite of some tremendous interest in Part 1 of this report last May.
I’m purposely avoiding all discussion of mathematics, which is difficult, since ballistics is a discipline that heavily employs mathematics. But I’m not qualified to write about the math; and, more importantly, I know that 99 percent of my readers would be turned off if I were to write the report that way.
Last time we learned that the BC of a pellet:
• Is an extremely small decimal fraction compared to the BC of a conical bullet.
• Varies with the velocity of the pellet.
• Varies with the shape (form) of the pellet.
