Ok, I'm going to admit to something and hope it does not jinx me or turn out it is all just a fluke anyway.
I started shooting bullseye a couple years ago. My goal has been to do better from match to match, but mostly annual improvements. So far I have gone from high two hundreds the first year to mid to upper three hundreds the second year to this year I have a 445, 441 and 489 with a total 18-X.
The first thing I did was google bullseye and read up on trainging tips. I came across the U.S. Army training manual and printed it out. Year two I cut back on caffene for two days before match and none the day of. I also carry the "wheel of misfortune" in my shooting bag to make instant adjustments to my errors.
This year has been the biggest change, and I hate to admit to what I have done ... I actually adjusted my diet slightly, but mostly I have been getting some exercise. I can't believe how much difference it has made in steadiness of my hold and shot grouping.
I am already a week behind on smallbore, and I am looking forward to see what improvements I have there. Trust me, I have a lot of area for change there.
The key to practice is research what the successful are doing and imitate them. I still have a long way to go, as you can see, but so far bullseye is headed the right direction. Hopefully it will carry over to the other games as well.
