I hate running copper that big so I haven't pulled that much. I try to contract that out if possible. I do find that the jam probably on the southwire wire fill calculator is helpful as it gives a likihood of wires getting stuck.
Just curious what are you powering that needs 4/0 copper? That's a lot of power. If this is this 120/208 is moving to 277/480 a possibility? (And if this is 480V, I'm really curious about what you're hooking up) And do you really need a neutral? One note is that aluminum is a fair bit easier to pull and has similar ampacity at the larger sizes. Plus it's a lot cheaper.
