I tested mine out and like I said they should not be considered safe as they are over max loads but with 25.5gr of CFE 223 the 75gr hornadys averaged 2692 FPS out of my 1/7 twist 16" upper. Luckily I ran into mapper and he was generous enough to let me put his chrono in harms way. The primers were getting flat and I plan on bringing the next batch down a bit and using a thicker primer as well. Another note on the load when fired from a sar3 5.56 AK with no muzzle device there was no visible muzzle flash as opposed to the 55gr tula that had a very loud and visible fireball when fired in the same gun so I think this would be a good load for shorter barrels
