I have lost two deer this year due to switching broadheads. I shoot 100 grain 4-blade mussy 99% of the time and have great success. They were out of them and i went to the 90 grain 3-blade. You would think there would not be much difference in the two, wrong, i wouldn' t give a nickle for the 3-blade " JUNK" lost the last two deer i shot perfect with them. I never seem to loose a deer with the 4-blade and they bleed alot better. My coments obviously, hope you dont have as much bad luck with a new broadhead like i had, if you shoot Muzzys stay with the 4-blade,love to hear your coments and good huntn
