Mark I/II/93R: MKII + 93G range report and questions

Here are some results and pics from the day. First pics are from my savage MKII hunting 22 with sporter barrel. Last five pics are from my savage 93 22 mag hunting rifle also with sporter barrel. Targets are either 2 and a half in circles with 1in squares at top or 1in circles or squares. Its easy to tell the difference. In the first pics from my 22LR I had narrowed down the rifles favorite ammo to a few. I believe the photos leave no question who the winner is. In the 22mag pics I have a few questions. Any ammo besides CCI 40 gr standard 2000 fps begins to walk left as the barrel heats. Anyone ever seen this? Doesn't make sense. At first I thought it was me, but I can shoot great groups with 40 gr ammo. Any help is appreciated and enjoy the pics. All from 50 yards with wind gusting from 5 to 15 right to left or target straight back.

The next targets are 2 and a half in circles with a 1 in square at the top. The goal was 3 shots into the circle with 2 following into the square. These were done as fast as possible!
