A QUICK eye and a good shot pattern, that’s the 
game-getting combination. Given an old-timer 
with a reliable gun in his hand and the rest of 
the story is up to the shot pattern. 
Now the secret of good patterns is in the control 
of the gas blast from the exploding powder. This in 
turn depends upon the wadding in the shell. 
The wadding, 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 pres¬ 
sure and high-velocity without danger of jamming the pellets out of 
snape at the ‘ choke” or muzzle constriction. 
1 The Winchester System 
IVinchestef JVaddinS is the result of repeated experiments to 
determine the most efficient control of the gas blast. 
The special construction of the gives what is known 
■^s_Progressive Combustion to the powder charge. 
Combustion spreads instantly | through the powder charge. By 
the time the top grains of powder become 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 de¬ 
veloped at the rnuzzle where it is’most needed. 
Meanwhile, under the heat and pressure of combustion, the 
tough, springy Driving Wad hdiS 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 wadding and 
makes the hard-hitting, uniform pattern for which Winchester shot ' 
shells are world famous. 
• 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 thorough 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 seating 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. 25,000,000 rounds of ammunition are fired every 
year in testing Winchester guns and ammunition. $100,000 is spent 
annually in the inspection and testing of finished shot shells' alone.
