Since factory ammo works fine, it sounds like you're not generating enough gas pressure or inertia depending on your system. Is your AR gas or piston?
I suppose it could possibly be that your brass isn't being sized down enough. But, that'd more likely be an issue with the chamber closing and firing rather than picking up the next round from the magazine.
Are you neck sizing or full length sizing?
Are you using a small base die?
What is your actual load? brass, primer, powder weight, bullet, and COAL
