On that lines it was a general sitting around conversation.If I'm reading you correctly, the Tricketts are saying the 80-82's take wind better, but the 77's are generally a more accurate bullet. Meaning, a good wind reader may score higher with the lighter bullets. I 100% agree with that. Especially here in New England where we rarely ever see more than 2 minutes of wind.
I know several High Masters who run mag-length 77's all the way.
I cant remember another gent from reading who let me shoot his rifle and ammo and my score was the same as my set up. He was shooting well into the 90% range. So he basically said its you not the guns or ammo.
Im so rusty now and only shoot at SR target at 200 yards with a 3 moa 10 ring and struggle to keep prone slow in that 10,ring!
I have fun shooting even if I dont score well
