I'd go with aluminum myself. That's gonna be some cha ching. You can go with 4/0 AL and still be well under 5% and that's if you go the full 75.
But anyway, your local supply house would be the ticket.

I'm running a drop wire from a 200 amp sub-panel to a 75 amp panel 600 ft underground and that's what the voltage calulator calls for, I was looking to buy online cause of the price. If you have any other suggestions I could use all the advise I can get. Thanks Bill

Shipping cost on that much wire will eat up any savings you could find buying online.
It might be worthwhile to ask the power company about dropping another meter near the barn.

The shipping charges for 600+ft of 4/0 USE copper will be astronomical. Buy it locally (and buy aluminum, not copper. It will work fine).
I'm think about buying #4/0 al. wiring, do you think that be a big enough wire and also one place online has free shipping an is about $400 cheaper than the electrical supply house. Thanks I just contacted my local wiring supplier and ask for a price on the #4/0 al. wire, he said he had the wire and was a #4 and I said wasn't a #4/0 awg a bigger wire tan a #4 awg and he said no they where the same wire, that his wire has 2 #2 awg wires which equal a #4. I don't think he's right for the wiring charts I saw, cause a #4 awg al. wire is not big enough for my job, am I wrong?

No you're not wrong, he is. I'm not sure how you're pronouncing it but it should be four-ought. Tell him it's the size cable that's usually used for a 200 amp service. Also, it'll be XHHW. Not THHN/THWN
