I'm the same way in that I want one bag for a trip to the range. I use a backpack and in the bottom I have a harbor freight ammo box. I use that to bring whatever ammo I need. Usually some factory boxes and/or ziplocs of loose rounds as I always bring 2 or 3 calibers. The ammo box fits perfectly in the bottom of the backpack. Then I stack a soft double pistol case on top of that and top it off with earpro. Smaller stuff goes in the main accessory pocket of the pack. Targets go in the rear laptop compartment.
The bag is a lot heavier when I arrive at the range versus when I leave.
