If the group is crossing that is undesirable as they will get further and further apart as range increases..The correct option it to load a grain less powder at a time until they do not cross..In your case that should only be a grain or perhaps two..then you will have a proper regulation and a gun that is suitable out ot a couple of hundred yards...
What Ray said. Recoil starts at the first movement of the bullet, and if it is slower, more movement of the rifle up and sideways will occur before the bullet leaves the barrel. You may need to add to the front sight or file down the rear, also.
