Awhile back, this subject was tossed around quite a bit. It appears Nosler has made a number of changes to this bullet since its introduction back in the mid 1980's. I used the original ones in the green/red box, and thought they were pretty explosive. I understand the bullet has gone through maybe four "improvements" over the years with some of these Ballistic Tips. Unless you pay attention to the five digit number Nosler assigns to its bullets, you could wind up with "apples and oranges" without realizing it.
