HEVI-Shot®
Announces 2007 World Record Target Challenge
During
the 2007 National Wild Turkey Federation Still Target Championship
finals on 6 October in Edgefield, South Carolina, ENVIRON-Metal,
Inc., makers of HEVI-Shot® products – and particularly
makers of the World Record holder shotshell in every category, HEVI-13®
– will pay any person who shoots a new world record with a
HEVI-Shot® product in any class $10 per pellet for the target.
These classes will include 12-ga. Men’s Open., 20-ga. Men’s
Open., Lady Hunter 20-ga., Jake’s Hunter 20-ga., and Muzzleloader.
We
know that our new HEVI-13® shotshells will set many new world
records during the lead-in to the championships this year. Our many
days of development and testing have demonstrated this very clearly.
We wished we could afford to reward every shooter who posts a new
World Record at a sanctioned competition during the year.
But
in order to keep the lights on in the factory, and to keep producing
World Record shells, we’re going to raise the stakes for payouts
only to competitors in the final round at the biggest event of the
year.
We
appreciate the support of the many fine shooters who have posted
World Records during the past seven (my how time flies) years by
shooting HEVI-Shot® products when performance was on the line.
We will continue to support your efforts, individually and collectively,
during the coming year.
See
you in Edgefield,
Ralph Nauman
President

The
new Hevi-Shot 3-inch magnum load may change the way turkey hunters
view 20-gauge shotguns. Just how good are these loads? For pattern
density, I have never seen anything else make such an improvement.
While it is tough to get 20-gauge loads to beat 70-percent patterns,
in my test shooting, the new Hevi-Shot 3-inch magnum No. 6 turkey
loads averaged better than 90 percent with Full choke and extra-tight
turkey tubes.
Many shooters think a 20-gauge turkey gun performs the same as a
12-gauge, only with a smaller payload. Almost, but not quite.
A Full Choke shotgun in either gauge should put about 70 percent
of its pellets in a 30-inch circle at 40 yards. Because magnum loads
deliver more pellets, in theory, at least, the total number of pellets
hitting in the circle at 40 yards should go up proportionally. However,
magnum loads seldom provide so tight a pattern percentage as do
the lighter loads in express or high-brass loads, likely due to
more pellets squashing together during the trip down the barrel
and through the choke. When deformed pellets leave the muzzle and
encounter air resistance, they tend to spin away from the core of
the pattern.
Soft lead pellets deform the worst during firing, especially the
pellets at the bottom of the shot column that squish into the air
spaces between them. Plastic wad cups, copper and nickel plating,
and buffering material that takes up these air spaces all serve
to keep the pellets as round as possible, but plenty of badly out-of-round
lead pellets still leave the barrel.
The end result is apt to be a bit less improvement in hit count
than the extra pellets in a magnum load might seem to indicate.
Still, while the pattern percentage may suffer a bit, the many more
pellets in the 12-gauge magnum load more than overcomes the percentage
loss. But this isn’t always true with 20-gauge shotshells.
Regular 20-gauge shotshells barely reach the standard Full choke
pattern of 70 percent, and 20-gauge magnum shotshells almost always
turn even poorer pattern percentages. With a 3-inch magnum shell
adding but an extra 1/4-ounce of shot to the load, it sometimes
struggles to get even the same number of pellets in the 30-circle
as did the non-magnum load. Switching to magnum shotshells can actually
reduce a 20-gauge turkey gun’s effective range.
Hevi-Shot’s new 20 gauge, three-inch magnum turkey loads are
different. An attribute of Hevi-shot is that it does not deform
in its trip down the barrel, leaving it the same more or less round
shape. Detractors of the high-density pellets point out that they
are a bit out-of-round to begin with, and, yes, lead pellets are
more nicely round in the shotshell. But compare them after a trip
down the barrel, and Hevi-Shot wins the roundness contest by a wide
margin.
This seems to make a big difference in pattern density, especially
with tight turkey chokes in 20-gauge shotguns.
For my testing, I used a couple of fairly typical 20-gauge guns
I had on hand. One, a Mossberg 500 pump, is my wife’s rabbit
gun. I had the barrel cut and a Poly-Choke installed several years
ago, so for this testing, I borrowed a friend’s full-length
barrel that still had the threads for screw-in chokes. Mossberg
sent me two of their tight chokes, X-FULL and the vented X-FACTOR
turkey choke, both measuring .584.
The other shotgun was an older Winchester 1300 pump, also using
screw-in chokes that, interestingly, matched the same threading
as the Mossberg. The chokes fit in both shotguns. Winchester’s
regular Full Choke tube measured a tight .581 while the Winchester
bore dimension was just .002 tighter than Mossberg’s .618.
The slightly tighter Winchester standard Full Choke didn’t
turn in quite so tight patterns in either gun as did the Mossberg
vented tube, which gave me 90, 92, 92, and 89 percentages in the
Mossberg and 86, 90, 91 and 96 percent in the Winchester.
The tight Winchester choke provided 89 and 82 percent in the Mossberg
and 86 and 84 percent in the Winchester. Mossberg’s X-FULL
shot 88 and 90 in the Mossberg and 82 and 87 percent in the Winchester.
Impressive numbers, but only part of the story.
That 30-inch pattern-measuring circle was settled on ages ago, as
a way to measure effectiveness for hitting moving game. Full choke,
or 70 percent of a load’s pellets in the circle, indicated
a very tight pattern for long shots at game birds or waterfowl.
Modern turkey chokes and shotshells are better than that. The goal
is to center a tight core pattern on a target that isn’t moving,
and the pattern from a good turkey gun and load (excluding the occasional
stray pellet) is often noticeably smaller than 30 inches at 40 yards.
Circle diameters from 6 to 20 inches are commonly used to appraise
the vital core of the pattern with turkey guns and loads; I prefer
15 inches because it is small enough to show the pattern’s
potential, but still large enough to reveal any unevenly dense or
thin spots. A hunter should be able to center a gobbler’s
head and neck in that size circle when he pulls the trigger.
My pattern checker is a Plexiglas doughnut, 30 inches in diameter
with a 15-inch diameter hole in the middle. I center this over the
pattern, draw both the 15- and 30-inch circles, and then start counting
pellet hits. The 30-inch circle gives me the standard measure for
pattern density, but the 15-inch circle is a better indicator of
a turkey pattern’s true long-range potential. While 90 percent
of the pellets in the 30-inch circle indicates a really tight pattern,
putting 50 percent of the load in the 15-inch core circle indicates
a terrific turkey load. A 15-inch circle has half the diameter but
only a quarter the area of a 30-inch circle.
And looking at those core patterns revealed even better performance
with the new 20-gauge magnum Hevi-Shot loads. The poorest core pattern
was a respectable 41 percent, with most scoring around 50 to 55
and a single high of 60 percent. That one best pattern put 154 No.
6 pellets in the 15-inch circle.
Since shotgun patterns always vary, and even good guns and loads
occasionally throw a low count, a hunter should probably discount
the best patterns and instead look at the worst patterns when determining
guaranteed effective range.
Just how many hits in a 15-inch core circle is needed to guarantee
lethality? Enough that there is no “hole” in the pattern
where a turkey’s head and neck might not be well-hit.
I’d not quite trust the 20-gauge at a full 40 yards, because
at that range there were a few holes in the average core patterns
where a turkey’s head and neck might not take enough lethal
hits. I’d likely set a limit of 35 yards. But that’s
not bad, and who knows? Your gun might pattern even better.
Shot size is the other limiting factor when considering 20-gauge
turkey loads. When asked the proper shot size for turkeys, the standard
industry response is to pattern the gun with shot in sizes 4, 5
and 6, then hunt with whichever patterns best, and set your maximum
range accordingly.
But what about impact energy?
A size 6 plated lead pellet hits with about 2 foot/pounds of energy
at 40 yards. It’s a small number, but enough to break into
a gobbler’s skull. If you want more range than that, you might
consider No. 5 shot. After all, a size 5 pellet still hits with
about 2 foot pounds at 60 yards.
The problem is that a 1-1/4 ounce load of No. 5 shot has fewer pellets
than the same weight load of smaller No. 6 shot. If there are 281
pellets in a No. 6 shell, there are but 212 in a No. 5. If 50 percent
of both hit in the 15-inch core, there will be 140 hits with the
No. 6 but only 106 with the No. 5, which is only marginally enough
to assure enough lethal hits. What good is an over abundance of
pellet energy if you can’t guarantee lethal hits?
It only gets worse with No. 4 shot. Despite their terrific energy,
there are never enough of them in the core of the pattern at 40
yards. In fact, 40 yards may be out of range to guarantee enough
lethal hits on a gobbler. All else being equal, loading a tightly
choked 20-gauge with No. 6 shot should get more effective range
than loading the same gun with No. 4 shot.
And
all of this penetration data is for lead pellets. Hevi-Shot No.
6 is lethal at considerably farther distances because of its higher
density. There is absolutely no question that these pellets are
lethal beyond 40 yards—that is, if the load patterns tightly
enough. The only way to tell that is to test the gun at the range.
Two other manufacturers have introduced 20-gauge magnum shotshells
with heavier-than-lead pellets, but these shells are offered only
with No. 5 shot. Maybe next year they’ll bring out the No.
6.
