6MM AI trim to length?

Spook

Captured too late to be fully domesticated.
What are you guys using as a trim to length for your 6MM AI cases? TIA
 
Unless you have a custom chamber that is shorter than SAAMI, your fireformed cases will be as short as you want them to be because they are going to shorten about .015". After fire forming, trim them to the length of the shortest ones. Mine are 2.215", FWIW.

I never trim them until they have been fired at least twice, and then try to find a happy medium to trim them all to.
99% of the time they do not need to be trimmed because of a length problem in the chamber.
Check your chamber for a overall length and go by that to trim to....... and .010 under will be fine as long as you keep a close watch on them..
It's nice to have them the same length but unless your running a full blown bench rifle
you may not notice the difference it will make on consistency in your groups....
