Shotgun Shell Loading Cost

The Shotgun Shell Loading Costs calculator computes cost to load shotgun shells (hulls) that require shot, powder, and wads.  It assumes new hulls with primers.

INSTRUCTIONS: Choose units and enter the following:

• (wtLDS) Reload Shot Weight per Shell
• (wtLDP) Reload Powder Weight per Shell
• (nRL) Number of Shells to Loaded
• (cBP) Ball Powder Cost per Can
• (wBP) Ball Powder Weight per Can
• (cWd) Cost of Wads Package
• (nWd) Number of Wads in Package
• (cSht) Cost of Shot Package
• (wtSht) Weight of Shot Package
• (cHL) Cost of Hulls Package
• (nHL) Hulls per Package

Shotgun Reloading Costs (SRC): The cost is returned in U.S. dollars. However, this can be automatically converted to compatible units via the pull-down menu.

• (SRC) Total Cost to Load or Reload Shells
• (PdC) Powder Cost
• (HC) Hull Cost
• (ShtC) Shot Cost
• (WdC) Wad Cost
• (CpS) Cost per Shell

The Math / Science

The Shotgun Reloading Costs function computes a cost per shell (load) for reloading your own gunshot ammunition.

Firearm Calculators

• Sectional Density: Computes the factor used in the computation of the ballistic coefficient called sectional density.
• Bullet Ballistic Coefficient: Computes factor that represents a bullet's ability to overcome air resistance in flight.
• Ballistic Coefficient from Bullet's Mass, Diameter and Form Factor: Estimates the ballistic coefficient from the mass, diameter and form factor
• Miller Twist Rule: Computes the optimal barrel twist rate for stabilizing a bullet's flight given the bullet's diameter, length and mass.
• Taylor Knock-out Factor: Calculates a factor indicating the power of a round,.
• Greenhill Formula for Optimal Rifling Twist Rate: calculate the optimal barrel twist rate for stabilizing a bullet's flight given the bullet's diameter, length, specific gravity and velocity. 
• Bullet Flight Range: Computes the maximum range (horizontal distance) traveled by a bullet based on the muzzle velocity, elevation angle and shooter height.
• Muzzle Energy of a Projectile: Calculates the kinetic energy in a bullet immediately after leaving the barrel given the bullet's mass and velocity.
• Recoil Velocity of a Gun: Computes the velocity at which a gun will move in the opposite direction in relation to the projectile that it fired.
• Cost per Round: Computes cost per round of ammunition based on the cost of a container of cartridges and the number of rounds in the container.
• Rifle Sight Correction Angles: Computes the Minutes of Angle corrections for rifle sights.
• Shotgun Shell Reloading Cost: Computes the cost to reload used shotgun shells (hulls) with powder, shot, wads and primers.
• Shotgun Shell Loading Cost: Computes the cost to load new pre-primed shells (hulls) with power, shot and wads. 
• Metal Ball Weight: Computes the mass (weight) of a spherical metal (e.g., steel) ball based on the size (diameter).
• Metal Cylinder Weight: Computes the mass (weight) of a metal cylinder based on the size (diameter and length).
