Lone peak Razor ti barrel thread

At that price from brass, I would get it chambered in 7rm and carry on till 7 prc becomes popular enough that components and ammo are in most local shops. Then consider rechambering or rebarreling depending on rounds counts.

Rechambers aren't an option to the above the blasers to fat

My bad , I felt to properly read the beginning where he has already the rifle in that caliber.
28 nosler could be the next approach

[Kelton]

Potentially 7lrm? I'd store it as a blaser barrel before going the 28nos

[Friwi]

Maybe you could push some 300 prc brass through the blaser die, trim and neck turn and be good to go?
A long and fastidious process.
