.223 Rem/5.56 NATO NAS3 Load Data?
Starting load development with Shell Shock NAS3 Cases - anyone have some load data they could share? For reference, I will be developing the load for my AR - presently have a Ballistic Advantage SPR profiled 18" barrel with Wylde chamber and 1:8 twist rate. Barrel has a rifle length gas system with Rifle Speed adjustable gas block. Barrel is profiled for the OPS 12 Suppressor - will run an OCM5. Want to try the Sierra 77 gr TMK, Berger 80.5 gr Fullbore, and Hornady 80 gr ELD Match. Have some modified magazines to allow loading beyond Std 2.26" COAL so I would also like to see if I can get the 88 gr or 90 gr projectiles to stabilize. Appreciate any/all comments and assistance.

Nosler, Sierra, Hornady websites usually list the appropriate twist rates for all their heavy and long bullets. Some can be controlled somewhat by higher velocities and super long barrel lengths. Info FYI: Trail Boss:
Available. Going fast. Expensive. Only 2 single 9oz allowed per customer.
GOOD LUCK. I'll keep looking.
