These broadheads are the most accurate fixed blade broadhead i have ever tested on my Bowtech Stryker Max 4 Crossbow that shoots 405fps (276MPH)i had 3 shoots in a 3/4 group at 20 yardsand 5 shoots in a 2" group at 40 yardsthey did not shoot the same excact spot as my feild points but because they group wellthey are worth resighting in forNo other 1 3/8"" cut broadheads shoots this accurate at these High Speed and their 100% Stainless Steel and reolaceableIf they can handel these High Speeds then anything slower should shoot just as Great!"""
