The 3 petal is what I am going to stick with. I will probably work on reducing my number of harversters, but for hunting I know what will go to the field. The harvesters started looking like a shotgun pattern when I got above a 90 grain load of 777. It is kind of strange how the different sabot and bullet combos work. At 80 grains both hit about the same point of impact. I just prefer a little more velocity for hunting so it will be the MMP 3 petals.
