I had to shoot some of the (false) economy ADCOM ammo today for a project. Average of one blown primer per box. This is from the infamous 98 lot. Primers lodged firmly in the FCG, a couple in pieces. Terrible accuracy, too.
On the upside, it shot to identical POA as (genuine) M855, and approximated BHA 68gr OTM.
One of the few loads that seems to have some consistent availability. Caveat emptor.
