Today I am trying a load of 25,5 gn of TAC Mil Brass, Fed primers, in 2 rifles a 5.56 1:7.5 Wylde Chamber and a Contender Carbine that I built several years ago with a Green Mountain Barrel that is pretty stiff and 20\” long. The 5.56 AR also has a 20\” barrel. I was just wondering if anybody else was using TAC powder? Has anyone shot coyotes with these bullets, if so, what was the hide damage? TIA
