confirmed it 2 years in a row....my 125gr 3 blade muzzys and/or my CX XP selects are fussy....gotta find the right broadhead ferrule that shoots right on whatever shaft.....ive honestly swtiched ferrules and had arrows hitting off target....usually "close" within a 1-3 inches at 20yds....but if i have them on the "right" shaft i can drill golf tees...got 4 matched up right now...got 4 more shafts to find ferrules for....got about 2 dozen sets of practice blades...blades have never made a difference but ive seen ferrules make a difference many times....so the shafts and ferrules get numbered once i find the right combo and they stay together all season....and i can also shoot FPs if i keep them all marked...
