Chambering a barrel for a specific factory ammo?

[littlepod]

If I plan on only shooting Prime 175gr for my 308, when I order a custom barrel from say SPR or StraightJacket, is there something specific they can do to make it shoot that ammo better?

Since I'm not handloading, I was wondering basically to customize the chambering to the factory ammo.

Specific freebores work better with certain bullets. You are basically setting your bullet jump/distance to the lands with the freebore

Thanks! I noticed that for 6cm chambering they offer different free bores. Didn't see any configuration for .308. I'll investigate.

Have you used straight jacket before..those are the barrels encased like a proof but not carbon fiber?

Or I’m remembering incorrectly

I meant straight jacket armory, not the straight jacket barrel -
