These are 3 shot 1000 yard groups from a Rem. Sendero 7mmSTW.
180 grain Berger hunting
Mark 4 6.5-20
wind was 3 mph from 2 oclock
The group in the red had two touching and one about an inch below
I didn't have anything with me to measure them with, but the red circle is 10 inches and the white dot is about 1.5 inches
I also have a 300 ultra 700P that is grouping well with 210 grain Bergers seated to fit in the magazine, but not as good as the STW.
