The CFE223 worked great in 223, I tested it with number of different bullet weights in my AR and bolt guns, all gave great results. Sense it's available at fairly good price I picked up 8lbs jug and have loaded 1k rounds for my AR. It seems to burn cleaner then varget and I don't have to clean the copper fouling.
Back to the 7.62, I loaded up some test rounds going of the 308 loading data. The Hornady's 150GR SP shot great, four loads that I have tried were all under two inches at a 100. The slower one was very close to an inch, and all those where with iron sights. My chrony refused to work today, so no velocity readings. So the new CFE will be my go to powder for now.
