FTR 200-215grains shooting technique question

[Ilya S.]

Lets look at this two guys. They are awesome shooters. It isnt 100% shoting process, may be just pose..
May be someone explain their tech(if its not winning secret ) ?

Derek use left hand to push the rifle into shoulder pocket ?

Jeff use a maximum cheek pressure and free shooting hand(just staying in air) ?

Best

can someone explain John Ingram's technique and show pics of his rig. May be some 100-300yds targets and tech tips of Jeff Rorer and Derek Rodgers ?

I love data and this is excellent information! What is the powder used in this series? What signs of pressure where observed?

Randy, it was Varget, in Qload on my 30-inch barrel model it was 4400-4500 bar on 44.6 grains. So plz dont repeat it. On this pressure, Lapua 308 standart(non-palma) brass life is 4-5 cycles. Extractor groove dia is 0.405 on new, 0.406-0.4065 after forming, and 0.407 after 5 cycle.
