about 60 ft. per second. Therefore, in the time saved by 
No. 3 shot, as compared with No. 6, the amount would be 
(60 X 12 = 720 ins.) X '0049 sec, or —

3*5280 ins. 
which is just 3 J ins. 
To give No. 6 this 3|- ins. of extra forward allowance, 
the muzzle of the gun would only require a fraction of an 
inch of additional lateral movement — an amount too insignifi- 
cant to consider, and beyond calculation on the part of the 
shooter. 
As the forward edge of the pattern of the gun with No. 6 
shot is only ins. behind the forward edge of the pattern as 
made by No. 3, the difference is trivial as far as game-shooting 
is concerned, as a variation of 3^ ins. could not influence a kill 
or a miss at a crossing pheasant. 
The difference in time, for instance, between the arrival 
of No. 4 and No. 7 shot at a bird as much as 40 yds. distant, is 
so small that it need not be considered, and at ordinary ranges 
of about 25 yds., the time of arrival of the two sizes is 
practically the same. 
That large shot, as No. 4, travels much faster than a 
smaller size, as No. 6 or No. 7, and that for this reason 
the aim need not be taken nearly so far in front of a 
crossing bird, is a fallacy that is often accepted as a fact 
by shooters.
