I'll try to add all the information. A3O3, 2 groove NOS barrel, 220gr bullet 1.210 long and a 200gr bullet 1.110 long, velocity 1430fps. I have a pretty accurate load for both but looking at the holes I can see a slight amount of tipping maybe .050 -.070 at 100yds.
Thought more velocity might help but due to the weather I haven't tried speeding them up and afraid I might lose accuracy.
Any other thoughts?

You could just ignore the not quite round holes if you are satisfied with the accuracy. However, bullets that tip a bit at 100 yards may not be accurate at greater distances. I have a whole fistful of 1st place postal certificates shot with a rifle and load that usually produced such holes.
You are right, more velocity may produce round holes but may be more or less accurate.

Like John says, more velocity may make rounder holes, but also may not. Two quick things are: one, center of form is not the center of mass (the mould is making bullets slightly different on each side, crooked sizing, etc.), two, mechanical issue with throat, barrel or crown that induces more than normal yaw until bullet stabilizes.
Franklin Mann's experiments of 120 years ago showed that all bullets have some yaw for the first time of flight.
If possible, check group size at 50/100/200 yards for better comparison.
