Curious as to how this would be wired. Have 3 20a receptacles on same circuit about 300' away. Need to use #10's from panel as Homerun...lets just assume this one circuit is a dedicated home run back. Can you wire with #12's at some point and what determines where you use #12's? Thanks

The simplest in my opinion would be to take your #10's to the first box then pig tail #12's to the first receptacle, #12's from there on. Or mount a J box in the ceiling where your #10 & #12's splice together. Then # 12's to receptacles.

That's exactly what I was thinking just wasn't sure how long the #12's could be.
 
What size is the load? According to my VD calculator to stay under 3% VD you would need a #6 conductor with a 10 amp load or a #4 for a 15 amp or 20 amp load.
