Titegroup is a great powder for launching 255 grain cast bullets from 45 Colt revolvers at 850 fps with excellent accuracy. But it has no business in a 5.56 AR. What do you think would happen if you ran a drag-race car on Coleman fuel? I think pistons would fly into the next county as the engine explodes. I think that Titegroup in an AR would probably explode the rifle long before you achieve acceptable results.
