Ammo for first function tests

[dpete]

I'm in the process of putting together a 308 AR using Aero Precision parts and a Criterion barrel from Fulton Armory. The barrel has already had about 200 rounds through it but the rest of the rifle is brand new never fired. What would you suggest to use for ammo for the first trip to the range for the initial function tests?

For a function test? i just use whatever ammo i'm going to be shooting through a rifle most often. for accuracy off a bench, i'll pull out the match ammo.
