No birds get through his shot patterns 
T he successful sportsman 
knows that his bag de- 
pends almost as much upon 
the shot pattern, or evenness with 
which the shot spreads out and 
covers the game, as it does upon 
his gun handling. 
The secret of uniform game- 
getting patterns is in the control 
of the gas blast from the exploding 
powder. This in turn depends 
upon the iK'adding in the shell. 
The Winchester gas 
control system 
The \\ inche^tcr S y s t e m of 
Wadding and Loading is the re- 
sult of repeated experiments to 
determine the most effective con- 
trol of the gas blast. 
The base wads of Winchester 
shells are constructed to give 
what is known as progressive 
combustion to the powder charge. 
The ignition spreads to the 
sides, in all directions as well as 
forward. 
Lmder the heat and pressure of 
this rapid combustion the tough, 
springy driving 
w a d expands 
and fills the 
bore snugly 
completely seal- 
ing in the gas 
behind. In be- 
ing driven 
through the bore this wad offers just 
enough resistance to the gas blast to 
insure complete combustion of every 
grain of powder, so that the full en- 
ergy of the whole powder charge is 
developed at the muzzle. Thus none 
of the shot charge leaves the gun until

The hard-hitting 
ll'inchester p a t- 
tern is evenly dis- 
tributed. Xo game 
gets through, and 
no game is muti- 
lated 
it is being driven by the maximum 
energj- and velocity possible from the 
load. 
At the muzzle the expanded snug- 
fitting driving wad is slightly checked 
by the muzzle choke or constriction, 
while the shot cluster travels on un- 
broken by gas blast or wadding, mak- 
ing the hard-hitting uniform pattern 
for which Winchester shells are world- 
famous. 
Lnifoim shells. From primer to 
crimp, Winchester shells are so bal- 
anced in construction as to insure the 
maximum pattern possible from any 
load. The broad fish-tail flash from 
the primer gives even and thorough 
ignition ; the driving wads completely 
seal in the gas behind the shot ; the 
stiffness of the crimp or turnover at the 
shell head is varied exactly according 
to different loads, great care being 
taken never to stiffen it to such a de- 
gree that it offers undue resistance 
to the powder explosion. 
In addition V\'inchester shells are, of 
course, thoroughly waterproof, insuring 
true shooting in damp saturating salt 
air or drenching rains, and a special 
lubrication of the paper fibre prevents 
brittleness and splitting in dry weather. 
Clean hits and more 
of them 
To insure more hits and cleaner hits 
in the field or at the traps be sure your 
shells are ^\'inchester Leader and Re-

Rival for black powder. Leading hard- 
ware and sporting goods dealers in every 
community carry f\’inchester Arms and

The ll'inchester system of wadding. The wadding expands evenly, sealing in the 
gas blast all the way to the musxle, where the wadding is checked by the "choke" 
or constriction. The shot cluster travels on ahead unbroken. Actual test target
