Badlands "Shell Shock" 5.56 - snake oil?

[Wormydog1724]

I’m still loading 77gr SMK with 27gr AA2520 and 25gr N135. Speeds are right at 2900fps from an 18” and good groups, good enough for gas gun matches. Loaded a couple hundred 73gr ELDM but they disappointed me so I’ve been shooting coyotes at night with them lol.

I am running 20” barrel and bought 1000 cases to load up. If I can’t get what I want 2900 plus fps with good accuracy from Tac I will try 2520

I was really hoping N540 would get me there but no luck.

Well I already get 2900 with the 77tmk with Starline 556 brass and N540 out a of 20in tube. Defiance anTI action. No pressures. Was hoping to get at least 3050 with the NAS3 case.
