I must admit that I had serious doubts about winchesters new "blindside" ammunition. Everything about it seems to go against the very mechanics of scattergun ballistic preformance. However my partner used some this weekend 3" #2's and was stoning geese at moderate to long range. Was very surprised. I stuck with 3 1/2" BB's hevi metal and also experienced very good results..I understand early season birds aren't too tough but was still generally impressed with both loads.
