Tuning Daystate Red Wolf HP

Good day
Once again I am raising old issue of my guns accuracy, today I was going through its Test Report as attached. I observed that it was tested on JSB Jumbo Beast 33 grains. Interestingly I found that diameter of pellet is 5.5880 mm whereas I am trying JSB redesigned 23 grains having 5.52 mm diameter.
Do you think barrel will behave eratic with pellets having 5.52mm diameter. Please explain.
