I was out today to test 3 different loads for the 308. 175, 168 and 150 grain. This is the second time I was out for 175 and 168 grain ones. The weather was nice but a bit sporadic with wind. Wind was changing direction with gust around 10-15 mph. I noticed my groups for 175 was tight at 200 yards but still had 3 groups (out of 5)<=0.5 MOA. For 168 it opened up and was closer to 1MOA. For the 150 grain ones, the group was around 2.5" all at 200 yards. Is this expected? How do you deal with wind conditions when you go out to fine tune a load?
