From what I've read over at http://300blktalk.com/, the Lee dies aren't very good. I use the RCBS AR Series Dies Small Base 2-Die set with a Lee Factory Crimper. When I was doing my research, I ran across this post that details the process: http://imgur.com/a/bluJu

Go ahead and do yourself a favor by getting a Sheridan Slotted .300 Gauge. It is a very quick and easy way to see if you are putting out junk and helps to identify issues with brass.

For reloading supplies, Academy has primers and some .308 bullets. I've been loading up Hornady 150 gr FMJBT w/H110 for trips to the range. Kevin's and DSH should have powder from time to time. If you are looking for premium bullets, I can't recommend these enough for the price: http://www.midwayusa.com/product/214...d-hollow-point. You won't break the bank working up a load for those.

If you want some decent factory plinking ammo to break things in, try these: http://www.midwayusa.com/product/183...ProductFinding
