Freebore in 6.5 Creedmoor

[vonb]

I have a 6.5 Creedmoor barrel that supposedly has a .169 freebore. When checking measurements to the lands earlier, I came up with the following measurements for the two different Barnes Match Burner bullets:

Barnes 140 gr Match Burners: 2.055 BTO (to engage the lands) / Catridge OAL: ~2.658
Barnes 145 gr Match Burners: 2.080 BTO / Cartridge OAL: ~2.780

The chamber was spec'ed at .169 freebore which should be .030 less than SAAMI (.199). However, these measurements seems awfully short to engage the lands. Does this look reasonable or is my freebore shorter than .169?

If you had .030 to 2.78 your right at 2.8 which is saami coal. I'm assuming the 140 is a short bullet and engaging the lands at a shorter length.
