wadding and makes the hard hitting, uniform pattern for 
which Winchester shot shells are world famous. 
Fish Tail Flash, All Winchester smokeless shells are made 
with the new Winchester Primer—the quickest and most powerful 
shot shell primer made. Its broad fish tail flash gives even and thor¬ 
ough ignition. Every grain of powder is completely burned up before 
the shot charge leaves the muzzle. 
The Crimp, The required degree of pressure necessary in seat¬ 
ing the driving wads is worked out in combination with the hardness 
or the softness of the crimping required for any particular shell. 
Waterproofing and lubrication. In the cold damp air of the 
marshes, or under the blazing sun at the traps, Winchester shells will 
always play true. Winchester waterproofing process prevents them 
from swelling from dampness. Special lubrication of the paper fibres 
prevents brittleness and splitting in dry weather. 
Uniform shells. From primer to crimp, Winchester shells are 
constructed to insure the maximum pattern possible from any load and 
under all conditions. $100,000 is spent annually in the inspection 
and testing of finished shot shells. 25,000,000 rounds of ammunition 
are fired every year in testing guns and ammunition. 
Glean hits and more of them 
To insure more hits and cleaner hits in the field or at the traps 
be sure your shells are Winchester Leader and Repeater for Smoke¬ 
less; Nublack and New Rival for Black Powder. Write for our

M ost hunters agree that three shot pellets or more arc 
essential to a kill. Less than three may mean a cripple^ 
no matter what the size of shot or its velocity. 
Hence uniform pattern, i. e., an even spread of shot is 
essential to successful shooting, in the field or at the traps. 
The secret of good patterns is in the control of the pow¬ 
der explosion. Good, evenly distributed patterns are the 
direct results of a correct system of wadding scientifically 
adjusted to the bore of the gun and the load. The wad¬ 
ding, like the piston head of a gas engine, must give the 
explosion something solid to work against, so that the shot 
may be pushed out evenly. 
It must expand and fill the tube of the barrel, completely 
sealing in the gas behind it. No gas must escape to 
scatter the shot. 
It must offer just the right amount of resistance to the 
explosion so as to develop uniform pressure and high velo¬ 
city without danger of jamming the pellets out of shape at 
the ‘‘choke” or muzzle constriction. 
The Winchester system 
Winchester Wadding is the result of repeated experi¬ 
ments to determine the most efficient control of the gas blast. 
The special construction of the Winchester Base JVad 
gives what is known as Progressive Combustion to the 
powder charge. 
Combustion spreads instantly through the powder 
charge. By the time the top grains of powder beconie 
ignited the full energy of the burning powder behind is 
at work. 
Though the explosion is almost instantaneous, it is none 
the less Progressive, the final energy and maximum velocity of 
the completely burned powder being developed at the 
muzzle where it is most needed. 
Meanwhile, under the heat and pressure of combustion, 
the tough, springy, Winchester Driving Wad has expanded 
to fill the barrel snugly all around. No gas escapes. It is 
completely sealed in. The wadding pushes the shot evenly. 
At the muzzle the shot pellets slip out without jamming 
while the wadding is checked for a brief interval by the 
constriction of the muzzle. It follows some distance behind 
the shot pattern. 
The shot cluster travels on unbroken by gas blast or
