Slamfire, what do you think about AA4064 in 5.56 LC brass with a Hornady 75gr?
I loaded a few up from 22.5-24.5gr set to 2.25 OAL. The 24.5gr really got crushed and because the BTHP has a lot of room in the hollow point cavity it deformed from the press. Basically it made the loads pinch the tip making it now 2.26 OAL. I didn't want to press them down further because that'd set them to low because it was the tip giving a longer reading. I just sand papered the tips back down to 2.25.
I did notice the LC brass was fine but I couldn't load any 223 brass as the powder came way up into the neck. Any advice?
