I have sluged the bore of a rifle that I want to run CB through and it is .313 (SKS if you are wondering) Now do I buy a 313 sizing die or 314?

.314 or .315. You need to be at least .001" over groove diameter.

The reason I might consider going .315 is your reading of .313 is the smallest groove diameter you have in that gun. You actually need to be a little over the largest groove diameter.

If the slug was nice and tight all the way through, then I would say .314 is fine. However, if it was tight at muzzle, but less so further down, I might think .315.

Also depends on whether you can get reliable function with ammo loaded with a .315 projectile.
