Very nice shooting. Obviously some luck involved but you don't get lucky if you aren't already very good.
Reminds me of being a poor college student going to the 100 yard range where I was a member and shooting my relatively new-to-me CMP Garand. I was sighting it in, and being of VERY limited means I did not have an optic of any kind. So I had to wait for the one other guy on the line to finish shooting to go check every shot after every adjustment.
After just a couple shots, he finished up and took sympathy on my situation and offered to spot for me with his scope until I got zeroed. I fired one, made an adjustment to center, then another which he called dead center. I fired another with no adjustment, which he called a complete miss. Shooting a ton of iron sight at the time I did not believe it and asked to look through the scope.
That wasn't a miss, I told him, I just put it through the same hole. We made a $5 bet on that, and I went to retrieve the target. He was incredulous that, indeed, you could just see the ovaling of the hole where the second bullet had gone through. Shaking his head, he offered me the $5 (which I told him to keep for his help) and he left.
I DID fire the third shot, once he was safely gone. About an inch off the other two. Still not bad.
