I bought a box of the gold medal match 185 Juggernaut bullets from federal. I'm trying to duplicate this load.I have 350 bullets. I took one of the cartridges apart weighted the powder and it was 44.90 gn of what looked like cfe 223. Tried it out with the Lab radar and it was 2587 fps and a little hot. The GMM load was 2475 fps ish. Any one know what the powder is in the new 185 GMM load?
