Very pretty.
But like I said, you cannot get Lapua performance out of a .308
Do you have data that even
indicates that a 15% increase in velocity can be achieved by just changing the freebore length? There is a lot of data out there that shows there is a measurable loss of accuracy by increasing the freebore.
Although, some people think that too much free bore will start to decrease the velocity, similar to an eroded throat...

Most people are of the opinion that increasing the freebore gives better velocity not because to the drag-free jump, but the allowing the bullet to be seated further out giving more usable case volume.
(EDIT Since we have a COL limited by the magazine, we cannot use this particular advantage.)
