Enter the velocity of the projectile as it leaves the barrel (FPS) into the Calculator. The calculator will evaluate the MPBR. MPBR stands for maximum point-blank range.

MPBR Formula

The following two example problems outline the steps and information needed to calculate the MPBR.

MPBR = PV / 10
  • MPBR is the MPBR (yards)
  • PV is the velocity of the projectile as it leaves the barrel (FPS) 

To calculate maximum point-blank range (MPBR) in yards, divide the projectile velocity in FPS by 10.

How to Calculate MPBR?

The following steps outline how to calculate the MPBR.


  1. First, determine the velocity of the projectile as it leaves the barrel (FPS). 
  2. Next, gather the formula from above = MPBR = PV / 10.
  3. Finally, calculate the MPBR.
  4. After inserting the variables and calculating the result, check your answer with the calculator above.

Example Problem : 

Use the following variables as an example problem to test your knowledge.

velocity of the projectile as it leaves the barrel (FPS) = 300

MPBR = PV / 10 = ?
