The German hunting guns manufacturer Blaser Jagdwaffen GmbH started to manufacture combination guns already
in the late 1960. Blaser D99 -drilling was introduced to the market in 1999, in addition to the same construction
based on twin rifle barrel D99 Duo was introduced in March 2000 at the IWA Fair in Nuremberg. Later came the
model D99 Trio, with all three barrels, are rifled.
Drilling is a folding weapon for hunting, which usually has two shotgun and one rifled barrel. In general,
the rifle barrel is placed under the shotgun barrel, but in the Blaser D99 -drillings the rifle barrel is
placed on top of the shotgun barrels. When the rifle barrel is placed on top of the shotgun barrels, the
aiming line will not be unnecessarily high. The low aiming line, in turn, makes it easier to take the
elevation lead into the shooting distances of different lengths.
Blaser D99 -drilling have three barrels (length 57.5 cm), two of which are am improved cylinder choked
shotgun barrels with caliber 20/76 and one rifled rifle barrel with caliber .243 Win. For the rifle
barrel there are a number of different caliber options, including; .222 Rem, .243 Win, 6.5x55 SE,
.308 Win., 30-06, 5.6x52R, 7x57R, 7x65R ja 9,3x74R.
Blaser D99 -drilling has a so-called Jäger -breach block mechanism, which was patented in Suhl by the
rifle manufacturer Franz Jäger over a hundred years ago in 23.11.1906. On the breach block mechanism,
the end of the barrel is closed with a separate closing block (bottom part), which contains the firing
pins. This breach block at the same time reduces the recoil effect on the firing mechanism itself. The
Jäger -breach block is very strong and stable, allowing the use of lighter metals elsewhere in the lock
body, which in turn reduces the total weight of the gun.
The weapon has a double-trigger firing mechanism. The frontmost trigger releases, depending on the
position of the selector, either the rifled rifle barrel or the right-handed shotgun barrel. When the
selector is in the top position, releases the frontmost trigger of the rifle barrel. The rear trigger
releases, regardless of the position of the selector, always on the left-hand shotgun barrel. The barrel
selector is positioned to the right of the trigger guard and the other end is visible on the right side
of the folding latch.
There is no trigger pull tuner (snellar) in the weapon, because the trigger pull is really good. The
weapon has a so-called Double Lock System, which means that the weapon is cocked only when the shooter
cocks it by pushing the cocking slide to its front position. Usually drilling is cocked when the gun
is folded and then closed.
The Rifle barrel is free-floating (Thermo Stabil), which means that they have not been soldered onto
each other. The advantage of this is that the hit point will not change with the thermal expansion
of the barrels. Barrels and cartridge housings are manufactured by cold forging, of the toughest
possible steel quality. The lock frame is anodized and the surface of the barrel is nitrided to
ensure maximum protection against rust. The contact surfaces of the barrels and the lock are
The Drilling's shotgun barrel endures for steel and magnum cartridges firing. The weapons inspection
center has hit the proof markings at the gun, the German eagle under which the letter "V", and the
French Lily-sign. V = "Verstärkter Beschuss", i.e. freely translated, the weapon will withstand
magnum cartridges for greater gas pressure. In turn, the French Lily-sign means that the drilling's
shotgun barrel can be fired with steel-loaded cartridges.
In the Drilling, the barrels are aligned so, that when firing the gun all the three barrels
projectile hit points should be at the same or at least very close to each other at the
desirable distance. This should also be successful when using the optical sight device. At
least with D99 -drilling this distance is about 35 meters, apparently also with D99, when
the shotgun barrel is used with a Rottweil Exact 20/76 Slug cartridge. The Exact Slug cartridge
contains 26 grams of a Gualangi-type lead slug and plastic stopper with muzzle velocity of
455 m/s. When the Exact cartridges is used, the shotgun barrels slug hit points should be
located about five centimeters (5 cm) from the hit point of the rifle barrel.
Walnut wood, which is used in Blaser guns, is up to 300 years old and is imported from the Caucasus mountain range,
specifically Turkish from eastern Anatolia, Azerbaijan and Georgia. High in the mountains, in the most modern, arid
conditions, especially due to the long cold winters, trees grow very slowly. The slowly growing tree is harder and
thicker so the pattern of wood is beautiful. However, the wood which is used Blaser guns, is taken from the stump
part of the tree and its root trunk, which must be dug from the ground. Just root trunk cut into the so-called crude
blanks (a kind of planks). Blanks are treated to reduce the tannic acid contained in the tree, as well as to kill
mushrooms and potential insects. After treatment, blanks dry for months, particularly in ventilated storage areas.
After this, the blanks are cut and planned into their coarse shape. The blanks are dried further in a special drying
chamber where the blanks are kept for a maximum of five months, so that the moisture in the wood does not exceed 8
After the blanks have dried enough, the stock wood quality control is executed and the quality class of the wood is
determined. The blanks for the Blaser weapons are classified in nine grades (Grade 3 – 11). The more unusual is the
pattern of the wood, the greater the number that indicates the quality class and the more valuable it is.
The logs are cut to their rough shape by CNC machining, but the shape and surface finish is always handmade. The stock
is also available with a special, shiny "Super Finish" treatment. Wood parts of the gun is not recommended to be oiled
with weapon oil, but with a separate gun stock care oil/waxes.
Blaser BD14, presented in this article, all wood parts are Grade 7. The hand guard is a wider model with a darker,
ebony wood on its head part. The cheek deck is a Bavarian pattern and has an additional grooving, highlighting the
shape of a cheek set. Different engravings are available for the gun's wood parts.
There is possibility to have integrated recoil absorber (kickstop) inside the stock. Kickstop absorbs the weapon's
recoil by about 20%. The recoil absorber is a steel cylinder that is filled with granulated tungsten. The suppressor
adds a little bit of weapon weight, but as said to reduce the recoil and in addition stabilizes the weapon.
Blaser BD 880
The Blaser introduced in 1988 to the production of a new drilling model, based on the SLK -system (SLK =
Single Lock Action). The SLK -system was developed by Gerhard Blink and Meinrad Zeh. It was of one of the
most popular Blaser gun models and its production was continued until 1999 when the new gun model, Blaser
D99, replaced it in production. The Blaser D99 -drilling is still in production, 20 years of first introduction.
The Blaser D99 Trio and Duo models exited from the selection during 2018.
Blaser Jagdwaffen GmbH
The German gunsmith Horst Blaser founded the Blaser Jagdwaffen GmbH gun factory in 1957, in southern Germany, in the
Baden-Württemberg region, in the town of Isny im Allgäu. The first weapon models were the Blaser "Diplomat" combination
gun and the Blaser 60 BBF rifle-shotgun.
In 1997, Blaser merged with SIGARMS (current SIG Sauer Inc.) Group, but continued as an autonomous production and
development unit for the manufacture of hunting weapons. Today, Blaser Jagdwaffen GmbH is owned by German businessmen
Michael Lüke and Thomas Ortmeier. Their company L & O Holding GmbH & Co. KG also owns brands Mauser Jagdwaffen, J.P.
Sauer & Sohn, SIG Sauer Inc, SAN Swiss Arms AG, John Rigby & Co and German Sport Guns (GSG).
Today, the Blaser plant employs about 350 employees, producing R8 hunting rifles, BBF 95- and 97 rifle-shotguns,
D99- and BD14 drillings, and F3 and F16 shotguns.
