Tim,
Thanks for your insight. The reason I posted on this thread has to do with a 2 match day I had on Sunday. In addition to your post, another couple posts also peaked my interest.
We had sustained 20-25 mph winds at Chief City in Illinois on Sunday for the first match. We had higher gusts that lasted several seconds as well. The second match saw even higher winds, about 30-35 mph and over the top gusts, but with a difference in angle. First match, almost always straight left to right with little switches. The second match a quarter wind from about 7 o'clock with some switching back to 9 o'clock. There was no shooting 2 conditions, winds were pretty consistent. Winds were so extreme some shooters flags actually broke apart.
I did very well on the first match and learned quickly in the sporter card to look at only one flag. Now I do not shoot sporter very well at all. I shot 3 matches that weekend, 2 at Chief City, and one the day before in Iowa at Voelker's club. Those 3 matches completed only my 4th IR matches ever. Sporter is not my bag yet. I am primarily an ARA shooter, but benchrest is benchrest. The guy that puts the most holes in the center wins in both sanctioning bodies.
I did win 13.5 in the first match, took second in 10.5 in same match and was second in 2 gun agg by one X.
So to you and others, does shooting in extreme wind change the way you look at your flags. To the OP's original question, I used hold off for all six cards that day. I was shooting over 4 Ray Hill dual vain flags. 2 standard, 2 up-downers and 2 Bob....forgot his last name.....starts with a 'P' and lives in New York, windicator/flags. My fourth flag from the bench was one of his and gave the best information as to where to hold. Hold on the first match was high right on the in between line of the 2 black outer rings of the IR target. About 10 o'clock. Furthest I have ever held shooting a match. My other flags did not seem to matter that day. If the fourth flag was 90 degrees to the field the hold I mention scored at least a 10 most of the time. I lost interest in the second match, was running out of ammo and did not shoot as many sighters. Didn't really care, as I shoot IR for experience and practice, not points.
So, in closing, would I have shot better going to the scope and adjusting? Are there times in extreme conditions where you have found one flag dictating where you hold?
Happy when I saw this thread, I don't come to this forum very often, but knew a bunch of good shooters do. From my experience on Sunday, to the OP, I would say use hold off. To the rest that I have addressed, what do you think about my Sunday match day?
Thanks
