THE BARREL
The company has close to a century’s worth of tradition and
knowledge in the production of gun barrels. For the best per-
formance, accuracy and consistency, we drill the barrels from
a solid steel blank.
We believe that the use of a special steel, combined with a tradi-
tional method of deep drilling ensures superior performance in
terms of distance and shot-pattern distribution. Important im-
provements were introduced in 1997 and again in 2008, with the
introduction of a certified quality control system that documents
the various phases of production.
One of the first and most important requirements was the esta-
blishment of a technical specification for the steel used in our
gun barrels.
After a study carried out in collaboration with a team of me-
tallurgical engineers, Marocchi opted to use a steel with specific
high-tensile strength. This specification matches the properties of
gun barrel blanks known in French as “Saint Etienne”. Currently
Marocchi only buys blanks that are within the parameters nee-
ded to become “ Steel Saint Etienne.”
The combined use of steel designed to be worked when bored from
solid, also allows for better concentricity while being machined.
This results in impressive performance at greater distances, and
the reason we still mark our barrels “Steel Saint Etienne.”
The barrels undergo very strict control over this long process in-
cluding the final technique of welding-in the barrel rib. The choi-
ce of steel is only a part of our success though: as throughout the
manufacturing process, which lasts about a month, every stage,
test, and check is carried out by two engineers: both of whom
have ten-year’s experience in the use of sophisticated measuring
equipment (although this does not in any way substitute for tra-
ditional care and attention we give to all our products.)
Other notes: the weight of the blank before drilling is 4.5 kilos
for a 71 cm length. After the barrel is drilled and finished, it will
weigh just 0.8 kilos.
This method of drilling a barrel from a blank doesn’t alter the
composition of the material and the elasticity of the completed
barrel, whilst the alternative more usual method of hammering
the barrel can affect the structure and will compromise perfor-
mance.
Special care is required in the position of the stacked barrels,
where we use a special tool to guarantee the alignment of the
double barrels with the sighting rib. Allowing excellent results in
terms of mounting and precision.
Our attention to detail ensures constant improvements; - all
part of our trade secrets which makes the brand “Marocchi” so-
mething unique.
