MRR System – Sabatti shooting rifle barrels
All the barrels of our rifles are made with our unique Multi Radial Riﬂing MRR® System
Precision and consistency of our with MRR shooting rifle barrels are second to none designed and introduced by Sabatti
- HIGHER BULLET SPEED
- IMPROVED GROUP CONCENTRATION
- REDUCED NUMBER OF FLIERS
- LESS COPPER DEPOSITS
- LESS CLEANING REQUIRED
- EASIER CLEANING WHEN NEEDED
- LESS BARREL WEAR
Comparison between conventional rifling and Multi-Radial Rifling (MRR®)
With Multi – Radial Barrels two different radiuses alternate in order to positively grip the bullet geometrically without submitting it to extreme stress.
Group concentration is substantially improved due to the extremely tight manufacturing tolerances that can be kept while manufacturing Multi-Radial barrels. As a matter of fact the MRR® lends itself perfectly to our cold hammer forging. The resulting riﬂing proﬁle consistency is excellent and the overall quality of the barrels of our shooting rifles is increased.
The speciﬁc riﬂing geometry of the forcing cone in Multi Radial shooting rifle barrels makes it possible for the chamber neck and freebore to guide the bullets into the riﬂing more precisely and steadly than with the traditional riﬂing system – the bullet matches the barrel axis in the best possible way thus reducing the ﬂiers.
Under similar circumstances – less copper deposits inside Multi Radial barrels and, therefore, less cleaning is required. Also, when needed, cleaning is much easier to do than with traditional riﬂing.
Shooter can improve Multi-Radial barrel performance of Sabatti rifles by simply lapping the bores with abrasive paste pads with no fear of ruining the riﬂing edges like with traditional riﬂing.
