Hornady 22 CM Factory Ammo OAL

[Lowedog]

Does anyone have 22 CM in either 80 gr ELD-M or ELD-X factory ammo they could measure the OAL? I bought a Preferred barrel chambered in 22 CM and chose the SAAMI .081 FB with the thought I would be shooting the 80 grainers from Hornady. Knowing they load factory ammo in the 80 grain bullets I figured SAAMI was fine. I haven't found any factory ammo on local shelves so I bought some Peterson brass and 80 gr ELD-X bullets to load up. I've found that I'm contacting the lands at 2.66 while max OAL is 2.7. I'm know curious if I am going to be able to shoot factory ammo with this barrel.

Factory ammo is measuring 2.59 OAL. I loaded to 2.69.

Factory is on left, my dummy round on the right.

Thank you! Looks like the max COAL doesn't really match what you get with a SAAMI freebore chamber. I'm touching the lands between 2.645 and 2.66 with 3 different bullets. 62gr ELD-VT, 73gr ELD-M, and 80gr ELD-X.
