I size rifle cases with a pin holder only on the decapping rod and then separately expand cases with an RCBS cast bullet expander which is 0.002" less than bullet diameter. I try not to expand the entire neck, but leave an unexpanded section above the neck-shoulder junction to support the bullet base. Outside neck turning and then fire-forming achieves much the same result.
Here are chambered and extracted .30-'06 rounds which neither debullet nor telescope, although the foreparts of the bullets are forcefully pressed into the origin of rifling. They shoot well this way:
