    convert compound cross bow to ball shooter

    Hi guys i am looking to to convert a compound crossbow to a steel ball shooter with a rail and groove ala black mamba but am worried about the limbs seeing it as dry fire would a steel ball of same approximate weight as the bolt intended 300grs 22grams ish be sufficient not to damage the limbs?

    You could always get on of these.....

    Keeps the draw short to avoid limb damage.

    Thanks Andy i have seen that but it does lose a lot of the power, i am a Kostka follower on Youstube, i am hoping to come up with some mods to allow the full velocity to be extracted but not sure if it can be accomplished without changing limbs to something less fragile but again if i go to steel i lose the oomph factor.

    Austin -- yes -- if the mass of the projectiles are the same, the shape doesn't matter as far as potential damage to the limbs -- a pound of feathers and a pound of lead are still each only one pound  still takes the same energy to move them one foot.
