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.
