In the setup I'm showing there is no FL sizing die. I do my sizing on a single stage press. You may consider both a single stage and a turret as you can get both the Classic Cast single stage and the Classic Turret for a lot less money than you will pay for a Redding T-7. You will get a lot of use out of both types of presses.
To your point ... I don't know if the relief on the back side of the turret support on the Redding T-7 will allow clearance of the funnel as shown in my photo.
I'm a big Redding fan by the way. Here is a shot of my bench. You can see I'm also a big fan of Lee equipment.
