You and the 12-Yard
Bird
Part I
Taking pointed birds at 12 to 20
yards.
"Those methods, like the knowledge
so derived, is arcane beyond belief." From THE IRON
LANCE by Stephen R. Lawhead
Short range targets -- and pen raised quail, grouse,
woodcock and skeet stations #1 low house, #7 high house and
#8 high and low houses come immediately to mind -- present a
different kind of challenge. They come closest to typifying
the kind of hunting we get today with more preserve shooting
and with better trained, closer working dogs. We are all
seeing -- and taking -- more close range shots.
In a nutshell...
Your IMPROVED CYLINDER choke pattern (and all gauges throw
the same size pattern, remember) is only about 17 or 18
inches in diameter at 12 yards. With 409 #8 pellets (or 585
#9's) in an ounce of shot, the best you can hope for on game
birds is a near miss; because if you are right on at 12
yards, sardines for dinner had better be Plan B.

At the dawn of shotgun
history -- long before the invention of screw-in or
adjustable chokes and plastic wads with hard shot or
close working dogs -- everybody's shotgun had long
barrels and tight chokes optimistically designed for 50-
or 60-yard targets. What was needed was a way in which to
give these guns 25-yard capabilities.
The knowledge so derived...
And so in 1892, a Parisian gunmaker named Galand,
patented and manufactured a cartridge intended for
short-range shooting. It consisted of a paper cartridge
with a thin brass lining that was rifled so as to impart
a spin to spread the shot when fired. It was made in two
sizes. The first had a twist of about 12 inches and
according to Gough Thomas in his book, SHOTGUN SHOOTING
FACTS, published by Winchester Press, gave a spread of 50
inches at 22 yards. The second had a twist of 25 inches
and gave a spread of 35 inches at 22 yards. The spin
imparted by the twist was able to overcome the influence
of tight chokes.
It is obvious that European experimenters have been onto
something big with the idea of rifling in shotgun barrels
for the purpose of increasing pattern size. Recently a
reader in Canada wrote to say that a French gunsmith was
rifling barrels with one turn in 60" and claiming spread
patterns "at 5 yards an 18" pattern, at 10 yards a 36"
pattern, at 15 yards a 55" pattern and 20 yards a 74"
pattern."
In this country, Briley (800/331-5718) is advertising a
new Diffusion(TM) screw-in tube they are doing for some
12 gauge shooters and 20 gauge shooters. The way it was
explained to me is that they take a Skeet choke and cut
rifling grooves in it. They report that produces a
pattern "about 5% wider than CYLINDER." This translates,
if my calculations are right, into a 23 or 24" pattern
instead of the 17 or 18" that IC throws at 12 yards.
FABARMS introduced the new Lion Paradox at the SHOT Show
in 2002 -- an over/under with 12 or 20 gauge 24" barrels,
the top barrel of which is a TriBore(TM) System barrel
with screw-in chokes, while the bottom barrel has
one-turn-in-14" rifling in the last six inches of the
barrel at the muzzle. I have seen the 15-yard test
patterns comparing this Paradox barrel to straight
cylinder bore. It provides a dense, even pattern superior
in every way to CYLINDER!. For short-range targets -- and
grouse, woodcock, bobwhites plus some skeet and sporting
clays targets come to mind -- this new Lion Paradox is
going to be as popular in here as it already is in
Europe. The suggested retail price of $1,199 guarantees
it.
Arcane beyond belief
Time passes and parallel lines of inquiry and
experimentation continue. A variety of scatter, spreader
and brush loads ideas are created. Some involve
intentionally deformed shot -- one disc-like (flattened
shot); another cubic in shape. Another technique for shot
dispersion involved roughening the choke area of the
barrel walls near the muzzle to abrade the shot as it
left the barrel.
Brush loads have a plain uncushioned piston-like wad that
deforms shot pellets in the bottom 20% of the shot column
at ignition, with additional pellets developing a flat
side by passing down the length of the barrel,
unprotected by the wad. Spreader loads usually feature a
plastic fixture in, on or under the shot to encourage
shot to spread as it exits the muzzle.
Mail order catalogue houses that cater to the shooting
trade often offer spreader loads in 12 and 20 gauge and
reloaders can have all sorts of fun experimenting with
spreader or brush loads. Ballistic Products
(800/273-5623) and Precision Reloading (800/233-0900) are
reloading resources that can supply you with a wealth of
experience and the specialized products needed to get the
job done.
As you can see, research on enlarging short-range
patterns by influencing the behavior of shot pellets
proceeds on several levels: (1) modifying the barrel; (2)
modifying the choke; (3) deforming the shot pellets and
(4) deflecting the shot -- all aimed at enhancing pattern
size. The question isn't "will some form of pattern
enhancement make a FULL choke shoot like a MODIFIED
choke?" It will. The question is: "how do we apply this
technology for 12-yard targets?"
Rudy Etchen Jr., an All-American Champion trap and skeet
shooter and longtime friend, told me once that when he
was watching the Russian skeet team warming up for the
Olympics, he noticed that every shell in the box was
marked for the position it was to be shot at! Imagine
that. A game where the maximum range is 21 yards -- shot
with open skeet chokes -- and they still had special
shells, presumably with different patterning
characteristics, for each position on the skeet field.
"Those methods, like the knowledge so derived, is arcane
beyond belief." And the devil is, sure enough, as always,
in the details.
