    "MOST USED"?????
    in 30br undisputed .330 chamber.....

    I suspect in 300 blk out.... SAMMI is mostly used due to the fact that not too many custom 300 blk out chambers are around. I happen to have a custom 300 blk out chamber, and it is a .337 neck chamber.
     
    Hoodoo and mrjdasr like this.
