Hello,
I need advice on the following test results.
Background: all rounds where loaded with the same amount of powder; the difference is in distance to lands; the brass used to shoot on the white targets was FL seized with a neck tension of ~3 thou while the shots from the black targets where neck sized only with ~1 thou neck tension. The bullets for 1 & 5, 2 & 6, 3 & 7 and 4 & 8 are loaded with the same die setting, however, there is a slight difference in measured CBTO, neck sized ones tend to let the bullet seat deeper. There was an 11 mph wind from SW if N is facing the target.
What would you do next, assuming the velocity test was done and a nice node was found?
The rifle is a factory Tikka in 270 Win. Assuming I'm happy with the results which group/groups would you chose for hunting? Would you tinker with it? How?
TIA.
