Sorry for the delay, sounds like a release issue but take a minute to check everything out starting with your arrow, broadhead alignment, cracked nocks or misaligned nocks, spin test. Then the bow,,,brace height, twisted limbs, the way the string lays in the limb grooves, rest, and strike plate. Then shoot and when a arrow shoots off, isolate that arrow and shoot it again to see if it shoots the same. Are you shooting 2 or 4 blade Delta's?? Are you getting a whistling sound??
