Anyone heard of a .336 neck 30br?

"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.
 
no, barrel has a 0.243 bore and has a 6BR chamber and I open up the neck to 0.336 with a neck reamer with a 0.243 bushing
barrel is now a fireforming barrel without 6mm bullets bouncing off sides of the bore and being unsafe.
Doesn't that form a donut upon firing?
