Today I shot my Diana 54 in .22 at 50 and 100 yards. The rest I used has several tops so of course I took the one with the wrong bag, but I still came home happy. I started at 100 yards. Wind was predominately rt to left with switches to a tail wind going slightly the opposite direction. Tails were from 10 degrees to 90 degrees. I shot a dozen shots to get a feel for the wind then put a clean target up. First three shots where a triangle dead center of about 3/4 of an inch or a bit less. Fourth shot went a half inch rt of the first three, now 4 in 1.5 or a bit less. Fifth shot hit a quarter inch below where I held. First 2 flags went from rt or left 45 degree tail to a straight away tailwind with tails at about 20 degrees. So it went 2 inches left of my group leaving me with 5 in around 3.5. I was pretty happy. Then I shot 2 groups at 50 yards. Both around 3/4 inch. First 3 shots of the first group just made a fat hole. I was unhappy with this rifle when I bought it. After tuning by John Thomas and then adding Hectors tuner....I love it.
