Had my 101st target bow dialed in Tuesday, shooting really great groups @50 yards. Put a set of LS quads on and went to the range again Thursday. Couldn't keep my arrows in a 12 inch circle @ twenty yards. Tried a while but couldn't get it to shoot. Took off the quads and starting driving nails @ 20, 30, 40,50 yards. Does this make sense? Never had this happen before and was just wondering if I'm the only one!!!
