Sabot - That is some really good shooting. Looks like you have a great shooting rifle there. I was really examining your target and if you took all the shots at 50 yds (excluding the hang fire #3) and overlappedthem onto the 100 yd target, you would have 10 shots in an inch or just over. Which is excellent even for a centerfire rifle.
If some other guys would post a group like that I would suspect to see powder burns on the target.
Now you have me wanting to get out and shoot my Hawken today.
