You are seeing the affects of barrel harmonics. As the bullet travels down the barrel it causes the barrel to "whip" around. All guns do it, some more than others. Some change poi left or right, some are more akin to a shotgun with various weights of bullets. This is why many of us use only 1 bullet in a given rifle. I have 3 guns in 243 win. Each for different bullet weights and different uses.
You can't fix stupid....however ignorance can be cured through education!
