No I didn't chronograph those loads,but I will.I doubt any of the loads will make 2800fps.Probably in the low to mid 2700's.I use magnum primers in my rifles 30-06 and up so I wanted to try the 308 with them.Also ball powders are usually more accurate with magnum primers.
You are correct sir about ball powders and magnum primers
But this powder is not like BLc2 or 748 or H322 .
This powder is very hot, high energy powder ,mag primers are not required. Be Careful with this powder friend.
I also noticed I was reaching max way before Hodgdon website data.
