| When you bought the bow, it was advertised as 30-40 lbs That just tells you its best range. It could be that it is not set at 40 or 30. At the end of each limb, furthest from the string is a bolt that can be tightened with an Allen key.When that is fully tightened down, the weight should be 40lb. if your bow is a long way from fully tight, it could be lighter than the fibre glass one.
That may explain why it does not penetrate so far. |
