Looking at the two sets of results, I'd say the cigar has been given to the best pellet. I am using RWS Superfield in my slightly modded Scorpion and groupings wise, they are great. I have shot one hole groups at 35yds and can squeeze five into about 1/4" at 50yds on a good day.
Like so many other things related to shooting, pellet choice is strongly influenced by personal preference and confidence. This is why you see so many contradictory posts on the subject.
People often forget that when they sit down with their chrony and tin of pellets that there are many unseen factors which can determine the outcome of a particular days testing; the single biggest factor is the shooter. Are you having a good, bad or indifferent day? have you just rushed in from work? have you been testing pellets for three hours?...you get the picture.
Facts and figures do give us useful information but so does instinct
