I know AA always say that we shouldn't worry about that as the skirts will be blown round with the blast of air pushing them through the barrel.
I spent some time sorting out the ones with poor looking skirts and then went to the woods and tried some more groups with the sorted ones. Much better results with tight groups at 35 yards and groups @ 30 - 35mm at 55 yards.
I actually tried some Prems. The Prems are very very tight on loading. At 35 yards there were superb ... better than the AA's ... or at least more consistent and seemingly 'easier' to shoot tight groups at 35y. At 55 yards the AA's were slightly better and even though the AA's are heavier the Prems dropped more between 35 and 55 yards. I haven't tried the Prems over the Chrono yet so I'm expecting they will be down on power due to them being so very tight.
I wonder if it would help if the Prems could be 'sized' down a tad?
