Are the 120gr actually 125? I guess what I'm asking are they heavier than advertised? Was going to order but I think I will ask people that have the new ones first. I use 125gr Field points with my Wood arrows.
dad,I don't have the answer but it is a simple matter to put a tiny bit of lead shot or solder up in the broadhead ferrule,ahead of your taper.That Grizzly ferrule is deep and #6 lead shot is 2 grs per pellet.It doesn't take much to equal 5 grs.
Mine weigh in at 119 gr,without an adapter.With a short adapter,im hitting 145gr on the nose.I dont think that you would notice a difference of 6 gr.
They are likely longer than your field point. This should weaken spine. I doubt you would notice a flight difference, but as mentioned above weight can be added pretty easily.
