took it out to 300 yards today, testing .050 and .070 off the lands.
weather when I started was decent, but things got colder as I went, which may account for the second strings of shots being what they are.
temp: 42 starting, dropped to35 while I was shooting
wind. varible 2-5 MPH from 7 o'clock
Method: round robin, alternating back and forth between the 2 loads every shot to make two 3 shot groups. I then walked out and retreived the first target, posted the second, and then shot the second strings, reversing which load was fired first when alternating.
I am not sure why I got the big vertical spread on the second groups, I think I may have sped up my shooting because it was getting cold, I was taking notes between shots, but that's about it, there were no called fliers
I also got decent chronograph data this time, here are those results:

.070 off the lands:
