The .308 Winchester still does everything: 147 grain bulk for gas guns, 168 and 175 grain match kings for precision work, and controlled-expansion hunting loads that have anchored more North American game than any modern cartridge. Federal, Hornady and Winchester anchor the shelf.
Bolt gun or AR-10 pattern, we can match the load to the platform - semi-autos tend to favor the 147 to 168 grain range. Hunting seasons clear this shelf fast; stock up early.
