You know a good solid reliable dyanamic load, primers will not make too much difference. I can take my 308 load and put CCI's or Fed 210's and get pretty much same results. I can also move my COL from 2.77" to 2.83" and not see too much a difference in groups. I could shoot it in 20 degrees or 80 degrees. All would be under 1.5" at 100 yards. Thats what I love about a 308win. Not too many calibers I have seen can accomplish this.

Winchester primers are the one exception.
