I believe the Federal Gold Metal Match says Match on it. I didn't find the FC brass to be very bad in the 90's.
When I start Long Range shooting, I got a few cases of Hornady LEO only 165 A-Max Match. Great load (20 in same bullet hole@100) I used those 660 brass for several years.
I retired it to a ball load for the AR-10 and My Long Range ammo is hand-loaded 155 Sierra Palma over 47gr of Varget with Fed 210M and Lapua Match brass I'm sticking with the large primer, but many are going with a small primer brass (Called Palma Brass by several companies) and a Rem' 7 1/2!! My moto, If it works do not fix it! This is from the Hodgdon Magazine load for 155 Sierra. I get 1/4 to 1/2 MOA out to 800 and sometimes 1000 yards! At 300 and less you can stack bullets by the dozen!
