The best dies?
I've reloaded using Lee, RCBS, Hornady, and even Herter's (I found a set of Herter's 6.5x55 dies used). Honestly you'll be able to make quality ammo with any set of dies.
Looking through Midway's offerings, I picked out three by price range.
Hornady's basic offering: http://www.midwayusa.com/product/543...t-65-creedmoor
Hornady's better offering: http://www.midwayusa.com/product/160...t-65-creedmoor
Although if money weren't an option, this would probably be the set I would buy. http://www.midwayusa.com/product/292...t-65-creedmoor
The three hundred dollar Redding competition set of reloading dies is probably worth every penny, but I can't see paying 300 dollars for a set of dies at this point in my life.
