300 to 400 feet is not that far. You just need to use bigger sized wire.
If you are running underground you can use copper instead of aluminum. Copper has a higher amp rating for a given wire size, but is more expensive.
Also remember that voltage drop depends on load. If you are going to have a shop with a lot of power tools this should be factored in. If it just a small house with gas appliances, then the calculation would be different.
