I have a rifle that shoots "Federal American Eagle 7.62x51 168 For M1A" very well. I am curious if anyone has information on the components in that cartridge to sleuth the load.
Thanks.
Thanks.

So what is the difference between Federal's GMM 168gr SMK load #GM308M and the American Eagle 168gr OTM load #A76251M1A?
The price is dramatically different.
American Eagle:
Crimped Primers, sealed primers Speer 168 Grain match instead of the Sierra.
Also believe the brass is a bit thicker, but don't take that for gospel.
That's a little strange that Federal would use Speer match bullets instead of the Sierras... Speers cost more in most places, and Federal already has a working relationship with Sierra, of course.
That said, they're probably using a ball powder here, as it's easier to meter and QC cost could probably be reduced a bit. They seem to use AA2520 in some factory loads.
Using AA2520 and adhering to published load data, you might be able to get a handload to work as well for you here.
This is *not* to say that Federal is using AA2520 here... just saying it's probably in the running.
