As I posted earlier, I just ordered an X-Caliber pre-fit barrel 6.5X55 SE. They told me that the reamer they use will have .266" of free bore, which the guy from X-Caliber said is not a lot of free bore. I ordered a 1:8" twist 5R barrel and I'll be shooting 140-147 gr high BC bullets.

Is .266" about the right amount of free bore?

Will .266" allow me to load theses bullets out to the lands?
