    I have an ar-15- dpms ap4 (16" m4 contour 1-9 barrel), I have stripped the iron sights off and am getting a lo profile gas block and optics. I have shot up to 62gr barnes ~(2800fps)through this rifle and they stabilized fine. Does anybody have any real world experience with trying anything heavier? Was hoping to be able to shoot 68gr hornady match bullets.

    This is the GATE section for long-range shooting so you will get only responses from the resident expert.

    Your 1:9 should definitely stabilize up to 69 grain. Some 1:9 barrels will stabilize 75's.
