first off this thread isn't intended to discuss why one or the other shouldn't be allowed in certain seasons. i am wanting to know why compound bows are held, for the most part, to the "5 grains of arrow weight per pound of draw weight" rule when crossbows are not held to the same standard? if they were both held to the same standard, a 150# crossbow would have to shoot a bolt with a minimum weight of 750 grains. looking at the weights of crossbow bolts, they are around the same weight as the arrow that i shoot out of my compound bow. is a crossbows limbs made that much more durable than a compound bows limbs?
