Multi-Radial Rifling (MRR).

[HIGHLANDBEAGLES]

I am looking for some firsthand feedback about Sabatti rifles and their Multi-Radial Rifling (MRR).
To be more specific 30 caliber magnums and or anything pertaining to the MMR.
From what I see, it reminds me of Medford rifling, and we all know how that worked out with high velocity smokeless powder loads.
Thank you in advance for all comments.

Metford rifling works fine with high velocity smokeless as shown by its use by the Japanese long after the British discontinued it. The issue with Metford rifling in British service was Cordite. Other powders work fine.

Proper made, gain twist rifling suited to the specific cartridge and bullet is best in my book.
