I have a new Tikka 223 take-off barrel, purchased from UM, never fired/currently not on a action.
Prepping for my trainer build, I purchased 1k factory 2nd 75gr BTHPs from Midway, likely Hornady with cannelure.
I just measured the max COAL to the lands using the hornady guage. I don’t have a 22 cal BTO guage yet, but measuring COAL for 5 bullets is giving me 2.1735 - 2.1810, with the cannelure seemingly 1mm below the top of the neck at this length.
This is way under the 2.26 COAL length I see as the standard Hodgdon and VV load data. I understand that Tikkas are supposed to have short throats…but what gives? The numbers I’m measuring seem to suggest it would be unsafe to fire factory ammo.
I’m hoping user error but I’ve tried several times and get the same results.
Thoughts?
