Hey, Rob - I just got back from the range and did not notice any significant difference. Both limb bolts were maxed out before - and I had to loosen to bottom one about 1/3 of a turn to get to measurements equal. Did not change the point of impact of the bow, group size,nor did it affect the paper tune. I didn't have the broadhead target with me, but would suspect that they are still shooting the same spot as field points as well.
