I just bought a new Savage 110 Precision 300 Win Mag, and I started off setting up my seating depth using the Hornady modified case & comparator, to measure off my ogive to the lands. I started my baseline using a factory Hornady ELD Match 180 grain cartridge. 2.7” case head to ogive. Using the modified case and a 155 grain Sierra HPBT, I measured 2.9” casehead to ogive, touching the lands. So my difference between the two is 0.20”. That seems to me a lot of freebore. 2.7” vs 2.9” touching the lands. This sound right? Or is the difference in the two bullets?
