Re: hold off or adjust for wind
I wanted to see how this one shaped up a little.
Camp Perry was a great example, i did both.
On at least 2 occasions I had 6.5 to over 7 MOA dialed in, I don't see me ever holding that much.
Sometimes you could watch the mirage and see it was pretty steady and click for the variations if it looked like the spotter was moving over slight variation in wind at that speed are really hard to see.
When it got variable but still brisk I just got eaten up. No experience with that much change and not sure of the values so I don't know if I did it right or not. In one case I read the letoff, held to the outside of the 9 and shot an 8 out the other side. Only once did I hold as far over as the 8 ring, and I still ended up with an 8 or a 9 on the other side. We had gruesome wind in that relay I managed to shoot a 180. I didn't like it but I didn't feel too bad either, especially after I scored the next relay.
I shot a 180 and a 186 in my worst two, and a 193 and a 190 in my two best matches, and in both cases missed the shoot-off by 3 points. The 193 was with about 7 MOA dialed on, the 190 started with 4.5 or so. In that match on the 3rd shot I dropped an 8 on a letoff or a quarter change that I didn't see, shot a second one to be sure

, took off a full minute and shot a third one. (pits said it was about a 2" group) At that point I'd dropped 7 points in 5 shots. I got in the scope for about 2 minutes and didn't see anything changing, so I dialed another 1.5 off and let one fly, got a 10. Then I fired for effect and finished with an X. I cheated off inside the 10 ring some, but mostly I just pumped them in as fast as the pit service could keep up. I dropped 3 more points and two were 9s at five and 2 o'clock, and I know I broke the one shot low right.
The match that I shot a 180 I put on 4.5 and shot three sighters, all Xs, only found it once again in the next 20 shots. There were several of us who got bitten by that snake.
What I did worked OK for me, but I didn't bring home any hardware either. I think if you are having to deal with rapidly changing conditions that you may want to dial an initial setting and then try to hold for the changes, until something looks permanent, if you have a pretty steady set of conditions, then you can dial it all.
