I think I'm going to order a pistol length blackout upper. My buddy uses the 240 lee bullet for sub sonic so that side is covered. Is there a cheap mold (like a lee) that is 100-120 grain that works at full velocity in an ar15 and runs right. I have no problem with a gas checked mold. I looked at midway and read the reviews there but none really mention the black out specifically. Only mention of the blackout with the lighter bullets is guys using them with bolt guns. Id really like something in that weight range that would have a similar point of aim to the jacketed hunting bullets.
