TO FIND WEIGHT

D-1. Multiply the quantity of expended cartridge cases by the weight. Using the example, brass, short, expended-rounds, .22 caliber, work the formula as shown below.

FORMULA

D-2. Quantity of the item     x     Weight     =     Weight of expended cartridge cases.

COMPUTATION

D-3. 39,875 rounds     x     .0008 lbs     =     31.9 lbs.
Work to one decimal place and round down: 31 pounds expended.

TO FIND QUANTITY

D-4. Divide the weight of the expended cartridge cases by the weight. Using the example, brass, expended-cartridges weight of .38 caliber, work the formula as follows:

FORMULA

D-5. Total Weight     ÷     Weight of the item     =     Quantity of expended cartridge cases.

COMPUTATION

D-6. 82.0 pounds     ÷     .009 pounds     =     9,111.1 rounds.
Work to one decimal place and round down: 9,111 rounds.
