Hmm... I see three shots holes in a steel bucket, in comfortably under three inches. The top left hole is larger than the rest, so perhaps it is a double, and this is actually four shots in under three inches.
There is also another shot on the bucket, about six inches low left. If it was part of the first three/four shots, then what I am seeing is an 8"-9" four/five shot group at 1000 yards. Which is good, first-rate shooting, that only comes from a good shooter firing a good rifle under good conditions. Well done, and I think that shooter probably has a fighting chance of shooting another sub-10" five shot group at 1000 yards with his gear (but I'll stick my neck out and say that it is most unlikely that he would be able to fire a sub-3" four-shot group at 1000 yards even one time in ten attempts)
I don't want to take away from anyone's accomplishments, but let's make sure we keep our assessments of what we are seeing, somewhat realistic. When I fire a five-shot group as best as I possibly can, it's usually the case that I can see a smaller four-shot sub-group, if I get to eliminate the least favourable of my five shots. Or, if I fire several five shot groups with the same rifle/ammo/conditions/etc, it's likely that one of them will be the smallest, and one of them will be the largest - if I'm being honest with you, I won't just show you the smallest group I shot, but all of the groups that I shot.
EDIT: '1000 yards', I hope you don't take the tone of my post above to be snotty or in any way denigrating your rifle or your shooting, it certainly wasn't meant that way. Since posting it, I've re-read the thread and perhaps have a better idea of what happened (and the explanation for the fifth shot - the elevation difference being intentional). It's pretty clear to me that you have a very nicely shooting rifle, and you know how to shoot it too. Sounds like you're having enough fun that you'll keep on shooting it for a good long time!
