Precision and consistency of our shooting rifles with MRR 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

Thanks to the new MRR® system, standard on shooting rifles and optional on hunting rifles, Sabatti barrels perform better with either monolithic or conventional bullets.

Every test carried on our rifles barrels out testifies to the substantial improvement in ballistics performance and accuracy of multi-radial barrels over barrels with traditional rifling, with either traditional lead bullets in cal .308 and 6.5 mm (.264”) or monolithic bullets. At standard pressure values, speed can be up to 10% higher than with traditional rifling under certain operating conditions.

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 shootong rifles is increased.

The specific rifling geometry of the forcing cone in Multi Radial 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.
