6mm BR Norma: Different from 6mmBR?

[gvnwst]

Okay, this is confusing me.
What is the difference between the 6mm BR and the 6mm BR Nroma? I still see them listed seperatly, but i can't find the difference. Anyone have velocity comparo's?


Thanks.

There isnt much velocity diff. They are just slightly different chambers. Most people that chamber a gun for the 6mm use the Norma chamber. Go to www.6mmbr.com to get more information.
