Back in the 1960s, I shot a .22-250 Rem 700 that shot well in "1-shot" turkey shoots, but because the rifle was so accurate, I decided to shoot only in prone matches, leaving the offhand matches to others. I'd usually win a frozen turkey within 5 targets, so that was good for putting meat on the table. The offhand matches were great for "lucky" shots and someone often "got lucky" and won, even though their rifles weren't the most accurate around.
One day, they needed one more shooter in an offhand round to be able to award a turkey, so they begged me to shoot. I agreed and when it was my turn, the crosshairs were all over the target, but just as they came down and crossed the target center, the rifle went off, "seemingly" by accident. The guys asked how I did and I had to tell them that it looked TOO good when it went off. When we went down to check, my target had a dead-center pinwheel...for the win! Never shot offhand there again...and was never asked to do so! I also never had a pinwheel in prone matches!
