This isn't a very big deal, but let me know what you think.
I mentioned this to a couple of people at the November FH gathering, and wanted to throw it out there to all the GMs for consideration. Most of the members of the Order of the Phoenix carried crossbows with them to this event. In general, they were a fairly useful tool, but I think they could have been more effective if governed by a slightly different rule structure than the standard bow.
Roland whipped out his bow and the archers engaged in a bit of target practice on Saturday night. I noticed that compared to our crossbows, his long bow proved to be more accurate (in the right hands), shoot further, and much faster than all of the crossbows. I was assured, and verified that the bow did not exceed the 25# limit for a ranged weapon as stated in the rules. As an archery fanatic, I realized, then, that I should have seen this coming.
Crossbows and bows behave incredibly differently with regard to their projectile's ballistics. If you were to take an arrow and a bolt with the same grain weight, and relatively comparable draw length and projectile length, and compare them, the following data is generally true:
Projectile Weight - 500 grains
DRAW WEIGHT - crossbow = 165lbs, Bow@100%eff = 67 lbs.
FEET PER SECOND (SPEED) - crossbow = 265, Bow = 260
Without going into the math behind the ballistics, it's easy to see that the speeds are basically the same, but the crossbow, in this case, requires almost 100 more pounds of draw weight to achieve it.
I'm assuming that the 25# standard was probably tested and established with a conventional bow, and not a crossbow. Offering myself as a target for Roland's bow to feel the impact, I think the 25# limit is fair for a standard bow.
Other things to note:
Conventional, simple, bows are physically quicker to cycle arrows than crossbows (I can get off at least 1.5 arrows in a bow to 1 bolt in a crossbow)
Conventional bows offer the option of fully helically fletched veins to provide better accuracy
The length of a standard bow's arrow is longer, providing even better accuracy.
If possible, I'd like to do some field testing to see if I can come up with a comparable draw weight limit for a crossbow, that would allow it to fire bolts with similar energy and speed to the standard bow. I have an available chronograph to measure the projectiles' speed so I can probably get it pretty close.
Again, this isn't a huge deal, and please don't think I'm an idiot for getting so in depth about it -- just trying to make a case.

Thanks for your time
