So I have a fresh 12fv 6.5 creedmoor here, and a box of lapua 6.5x55 brass. What are the chances hand reaming the original barrel .2xx inches deeper with a custom swedemoor reamer would actually work? I would keep the same shoulder angle and width as the creedmoor, just a longer neck and body, with a wider base.


If hand reaming is out, then Ill put the reamer funds into a new barrel. Thanks for any insight.
