A buddy of mine and his dad are down at Rifles Only this week doing the 6 day long range shooting class. 1000 yards. http://www.riflesonly.com/courses/pr1and2.html He called me today..second day of course has about 80 out of 750 rounds down range so far and was shooting at 600 yards. He is actually shooting Rifle Only owned rifles. AI`s with S&B glass .308 Said his shoulder was a bit tender. I`m jealous as fuck.
