I had a 22 rifle that would shout 1/2" groups at 50 yards with one particular load, A different load of same weight bullet and similar velocity would also shoot 1/2" groups, but 3 inches apart from each other. This at 50 yards.
When I ran a gun shop years ago, people would buy cheap ammo to sight their gun in and buy one box of premium ammo to hunt with, never checking for POI. As you have witnessed, this could be a miss or worse, wounded animal.
This is why it important to practice with what you will use in the field.
