Reb and I were talking about something I guess we should share. Bolt weight. Does anyone weight their bolts? I think we all should experiment with bolt weight and FOC (forward of center or percentage of weight forward). The weight ofcourse should stay over the recommended min weight but you may find that some changes may make for a more accurate xbow. Apparently some guys screw in weights into their broadhead adaptors as well as the obvious changing of target tip or broadhead weight changes. Changing the fetching will change the FOC as well. Then there are different shafts. My xbow doesn't seem to care much but yours might. Try it.
