Outdoors - I would be excited about shots 4,5,6. Not only are they a nice tight "group", they are exactly where you want them to hit at 50 yds. if you planto try them at 100yds. I would encourage you to shoot more than 3 shots in sequence if you are truly interested in what you and a particular load can achieve. I like 5 shot groups mostly because it seems like 15 shots is about my physical/mental/time limit at the range and gives me the opportunity to try several loads/distances. More shots in determining group reliability is always better IMO. Good shooting and keep at it!
