For many many years I shot the 130 grain 4 blade muzzys in my Hoyt 65 pound, last 5 years outta my Barnett xbow at about 380 feet per sec claimed velocity---you should see the deer drop or run only 30 -40 yards when hit with this set up ! Rockport I love your wisdom and thoughts but you are off on this one 6 guys in camp for past 20 years all shoot muzzy 4 blades all mature guys who have been bow hunting for a long time
