NUMBERS OF SIZES OF SHOT. 



In the above diagram are shown at a glance the relations 

 between the 1 oz. measure full of shot of different sizes and their 

 respective weights. The sizes of shot are given on the horizontal 

 line and the weight on the left-hand vertical line. Each division of 

 the vertical scale equals one grain in weight. It will be observed 

 that the weight of the ounce measure full of shot increases with the 

 smallness of the pellet. The irregularities from a smooth curve 

 observed belonging to shot of the sizes 3, 5, 8, and II, are due 

 to the fact that the diameters of the pellets of these sizes are such 

 that they do not chamber in the measure as closely as those of the 

 other sizes. 



This is at once seen in making the comparison of the chambering 

 in the bottom of the measure of one layer of 2 and 3, 4 and 5, or 7 

 and 8. 



This particular shot-measure gives too much weight for all the 

 lizes. A measure of No. 1 shot is about 10 grains in excess of the 

 ounce of 437^ grains, while a measure of No. 12 is 54 grains too 

 heavy. The difference in the weights of a measure full of No. 1 

 and No. 12 is 44 grains; in other words, a measure of No. 12 shot 

 weighs a little more than ,V of an ounce more than a measure of 

 No. 1, while the difference in weight of a measure of No. 7 and 

 No. 1 2 shot equals about 3V of an ounce.
