The Dragon .50 caliber rifle is
large. A handsome walnut stock is thin but deep, especially at
the forearm, where the two reservoir tubes must pass. Leaper's
5th generation compact scope is a nice compliment to the rifle.
Pyramyd Air adds another big bore to
their lineup, the new Dragon
.50 from Shin Sung. Shin
Sung is the Korean airgun maker who gave us the powerful and
accurate Career 707. They also gave us several variations on the
Career rifle, in the form of a standard carbine and the Tanker
Carbine that has a removable reservoir.
In the big bore realm, Shin Sung created the Fire 201
.25-caliber air shotgun that was the most powerful air shotgun
ever offered. That gun was eventually rebarrelled with a 9mm
rifle barrel to become the first big bore rifle from Korea, and
it's still very successful today. Later, they came out with the
9mm Ultra, a lever action repeater capable of several fast shots
in succession.
Now, they have the Dragon, and it's an exclusive from Pyramyd
Air. The big rifle is a single shot bolt action in a
conventional one-piece walnut stock. Pyramyd Air also special
.50-caliber lead bullets from Pelletman, and the bullets are
just as exciting as the rifle, as you will see.
The gun measures 40-3/4 inches overall, which is not too long,
but the weight of almost ten pounds without a scope is a handful.
The cross section of the gun is thin but very tall and it feels
like a big gun when you hold it up to your shoulder. The barrel
is a trifle under 23 inches in length and the line of the
buttstock is very straight, due to a tall cheekpiece.
The rifle comes without sights, so I mounted a Leapers compact
6-power scope in a set of B-Square fixed scope mounts. The
mounts clamp right on to the 11mm dovetail base that comes with
the rifle.

Leapers compact scope is a small,
lightweight hunting scope with 6 power and a 40mm objective lens.
Fifth-generation emerald-coated lenses throughout give it extra
brightness.
At the range, I started at 25 yards and was on the
paper target with the first shot. Because of the way this gun is designed,
you can't boresight it without a collimator, so to skip that step, the
closer you can get to your first target, the better. I mounted my paper
targets on a 4-foot by 6-foot sheet of cardboard in case I didn't hit the
target paper right away, but that proved unnecessary.
Before I describe how the rifle shoots, let me show you the three new
bullets Pelletman makes for this rifle. They are all swaged from pure lead
and they are some of the prettiest airgun projectiles you'll ever see.
They're packed in custom Styrofoam trays, 50 bullets to a box. Don't even
think of not using these bullets because I believe they are partly
responsible for the great accuracy the rifle delivers
From left to right the standing bullets
are 225-, 250- and 275-grains, respectively. Each has a hollow cup in
the base, like the bullet lying down on the left. Made by Pelletman
and sold exclusively by Pyramyd Air.
The bullets are all shaped the same and come
in 225, 250 and 275-grain weights. The principal difference other than
weight, therefore, is length. Each bullet is finished mirror-smooth, which
is a characteristic of swaged lead. There are no sprue marks anywhere on
the bullets and they look like they will shoot quite well, which they do.
One problem with solid bullets in an airgun is getting them into the
breech. Airgunners who have tried to load smallbore caliber solid "pellets,"
which are actually bullets by another name, know how hard they are to
stuff into the barrel. That's because the bullet is being engraved by the
rifling as it enters the bore. Think of a muzzleloading rifle and you have
an airgun being loaded with solid bullets, only in reverse. With a
muzzleloader, you use a short starter, which is a wooden dowel that can be
struck with a hammer to ease the bullet into the rifling. In a
breechloading airgun there is no short starter, so you are trying to start
the bullet with your thumb as a substitute. You will only load a few solid
pellets this way before you give up with a sore thumb
|
The Dragon has plenty of room for
all three bullet lengths. A loading ramp aligns the bullet with
the rifling as it enters the breech. All bullets fed smoothly
during the test, as the breech is properly relieved to accept
them.
|
Shin Sung has done the proper thing and counterbored their breech, so the
Pelletman bullets are easy as pie to insert. Even the longest 275-grain
bullet goes in with ease. And there is plenty of room in the loading
trough for the longest of the three conical bullets. I found the 225-grain
bullet to be the best performer on target. It grouped the best, which I
believe is due to its short length that stabilizes better at the
velocities the Dragon achieves. The 250-grainer was almost as accurate as
the 225, but in my tests, the 275-grain bullet lagged behind the other two.
The Dragon operates from a 3,000 psi fill of air. You fill it from a scuba
tank or a hand pump, though I caution you that because of the enormous
amount of air this rifle uses, you won't want to pump it. There are a
great many shots available, but I limited the total to five, with were in
pretty tight range of one another. I see no reason why 12 or even 15 shots
are not possible, though the first five will give the best accuracy at
ranges beyond 25 yards. I topped off after each five shots for best
performance.
I started shooting at 25 yards and moved back to 50 when the zero was
established. The Leaper's scope was a perfect compliment to the rifle's
intended hunting use and it was on paper with the first shot, which means
the scope rail is aligned with the bore.
Accuracy was okay, until I stopped resting the rifle on the lower
reservoir tube and rested it on the forearm instead. Then it went from
okay to superb! Take a look at those groups!
 
At 25 yards, five 225-grain bullets
cut a beautiful one-hole group.

At 50 yards, the 225-grain bullets
begin to spread apart, but still offer fine hunting accuracy.
At 50 yards there is some drop to
the bullet, but you compensate by sighting in at 40 yards, then
you're on from the muzzle out to perhaps 75 yards. A rifle like
this has a limited range, after all. Within that range, though,
it puts those bullets right where you tell it to, as long as you
do your part.
The power of the rifle I tested was a tight band from 185 to 192
foot-pounds, with the heaviest bullets getting the higher power,
as you would expect. I tested a brand-new rifle and it has been
my experience that after many shots the firing mechanism will
wear smoother and the power will increase a bit.
Velocity of the 225-grain Pelletman bullets ranged between a
high of 613 f.p.s. and a low of 581 f.p.s. for five shots on a
fresh 3,000 psi fill. The average for a five-shot string was 601
f.p.s., but the average for the first three shots was a healthy
609 f.p.s. That velocity gives an energy of 185.34 foot-pounds
of energy. The start screen of the chronograph was set five feet
from the muzzle and the day was 72 degrees F, with a humidity of
80 percent.
The 250-grain bullet gave an average velocity of 584 f.p.s. for
five shots and 589 f.p.s. for the first three. The higher number
works out to an energy of 192.63 foot-pounds. The 275-grain
bullet averaged 555 f.p.s. for five with the first three going
559 f.p.s. That's an energy of 190.86 foot-pounds. I give the
energy and averages for the first three shots because hunters
will either make the shot or not with those. Shots four and five
are for finishers, if required.
On paper the 250-grain bullet looks slightly better than the
225, but I'm staying with my pick because of what I saw on
targets.
There are other models in the Dragon's general price range and
they deliver similar power, so there is a choice of big bore
rifles from which the shooter may choose. Of the Korean airguns,
the Dragon is possibly the most accurate and it has the most
contemporary lines. It's also the largest caliber, which may be
a plus for hunters. It's a fine big bore that's worth the
attention of serious airgunners.
