Context to what I was saying:
Back in early February, Dan Ekstrom was doing load development for my F-Class TR rifle (308 Winchester) for the Berger SW Nationals at the Ben Avery range in AZ, that Sebastian Lambang would be using. We decided to use the Berger 200.20X Hybrid/Varget/Lapua Palma Brass, and CCI-BR4 primers. Also shot the 180 grain JLK Long-Tail. The group on steel is a 10 shot group at 500 yards is with the JLK’s.
The group on paper we shot today with the Berger 200.20X, but it was only 18° below zero, not counting the windchill at 600 yards. On the third shot, Dan called a flyer. He was shooting at paper blind, with no camera or pit. This rifle that Chuck McIntosh built shoots great with all 4 bullets tried.
The four shot group measures horizontally (.477), vertical is .957. The 5-shot group (including the called flyer) is 2.853 at 600 yards. Bartlein 10T barrel, Kelbly rings, and the Vortex Golden Eagle scope.
The video was to show the conditions, and the way it tracks
