This video details a reloading project for .308 Win using 175gr Sierra Match King bullets and IMR 4064 powder, aiming to replicate Federal Gold Medal Match performance. Testing involved a load ladder from 42.0 to 42.8 grains in a JP Supermatch barrel, with both suppressed and unsuppressed firing. Case capacity differences between brass types were highlighted as a critical factor for pressure management, especially with military brass. While accuracy was generally disappointing, the best group achieved was 0.902 inches unsuppressed at 42.4 grains.

This video details a .308 Win AR-10 build featuring a 20-inch JP Super Match barrel and tests 175gr Sierra Match King reloads using IMR 4064. The host compares handloads against Federal Gold Medal Match factory ammunition, both suppressed and unsuppressed. Results show factory ammo performed exceptionally well suppressed, while handloads tightened groups with increasing powder charges, peaking at 42.0 grains.
