I do most of my big bore airgun hunting with  
DAQs (in .308, .457, and .50 calibers), and
more recently the Career Dragonslayer. I like all
these guns; and while the DAQ .457 has
become my primary big game gun, I have found
the Dragonslayer a fantastic shooter and a great
medium game gun. The Dragonslayer did come
up to its limit on some big pigs I shot a while
back, but was all I could want when hunting
smaller antelope. Many people have asked me
what gun I’d recommend in addition to the
DAQs for larger animals, and I’ve been
shooting all the big bores I can get my hands on
so that I can offer and informed opinion.

The Sam Yang Big Bore 909 .45 caliber air rifle
is one of the powerful production guns out of
Korea. I recently ordered one to take out deer
hunting to see how it would perform on larger
game. I’ve now had a chance to use it quite
a bit for target shooting and in the field for

The Big bore 909 is a single shot .45 caliber
rifle, loaded via a port in the receiver that is
accessed by a sliding cover that is slipped
forward to open, then slid back to close after
the bullet is loaded. Cocking is achieved using a
separate bolt action, making this a two step
procedure to cock and load. The 21� barrel
has an internal diameter of 0.454 inches and is
threaded at the muzzle for accessories.

This gun is a real handful with an overall Length
of 42 inches and weighs in at a bit over seven
pounds. The two piece stock and forestock are
a nice Asian hardwood with decent checkering,
and for me at least, a fairly good ergonomic fit.
The length of pull is a little short for me, but I
intend to add a slip on butt pad. The gun comes
equipped with sling swivels mounted

The Big Bore 909 has a double tube reservoir
that fills to 3000 PSI using a male probe
(included with the gun) for charging. Unlike
many of the other Korean guns the 909 does
not have an onboard pressure gauge, which is
too bad as I find this a useful feature. My gun is
set up to deliver 5 full power shots in the 670
fps range with 180gr cast lead pellets.  This
yields a power output near 200 fpe, which
makes it a viable large game gun.

There is a varied selection of bullet weights and
shapes available. Pyramyd Airguns, the store I
ordered my gun through, makes pellets to order
for this gun; I tried the 170, 180, 190, and 200
grain versions but settled on the 170 grain pellet.
This pellet produced velocities of around 700
fps and proved to be fairly flat shooting.

The 909 is a fairly ergonomic package, though the
length of pull is a little short for me. Still, the gun
points well and I found it pretty accurate under
field conditions.
This big bodied eight point buck was hit further
back than I'd have wished, but was dead when I
walked up.
There is a variety of bullet styles and weights
available, to cover a range of applications. I
have found that round ball also is an
accurate and hard hitting projectile, that
penetrates suprisingly well.
While not really a tack driver, this gun is more than accurate enough to be considered an excellent
medium and large game gun. This fifty yard three shot group was easily in the kill zone of a
woodchuck sized animal.
