I haven't had any troubles flying with guns since 911. Main difference was that everyone got training at the ticket counter. I usually fly 3-4 times per year with a gun or guns and I always put the ammo in the same case as the gun. The only place that is a pain in the arse is Denver airport and that's only because TSA is full of it... If you ever have trouble with a ticket agent just ask to speak with a supervisor.
