Nice.
Holes like that have a tendency to grow in size exponentially with the amount of pellets you throw at it, so stopping at 3 or 5 is generally a good idea.
I made a 22 shot hole on my last shoot ( 51 yards ) but the hole was not terrible tall, less than a half inch, but it was however over a inch wide, somehow my pellets just kept going more and more left on that magazine. and the next magazine,,,,,, prompted me to pack up my gun and go home cuz clearly some things are still missing in my Maverick.
Some times i make 2 pellet groups so small i am almost willing to bet the pellet totally missed the target and berm, only the sound of the pellet entering the 4X4 we put out paper targets on is there alright, and no holes in the papers to the side of the target.
