Does all broadhead flight fly different from fieldtips? Last year I shot 60 lbs with 100 grain expandables and 27 in Red Head Carbon Fury 4560Blazer Vane shafts.The expandablesseemed to group the same as my fieldpoints. This year however I turned my weight up to 68 lbs and am shooting 100 grain muzzy mx3's. I am noticing a big difference in the groups between the tips. I hate to practice with my broadheads but if I have to I will. I was just wondering if there was something I could do or if I should try a different broadhead. Thanks for any suggestions.
