Re: Solid metal crossbow-bolts
A little googling indicates that the current top of the line crossbows launch a bolt at ~460 fps and have a 180 lb draw. The upper range of bolts seems to be ~440 grains , made of carbon.

Re: Solid metal crossbow-bolts
An inswing cheiroballistra made using spring steel coil torsion springs could be made to an arbitrary strength for a tool-free draw.
Kevlar string, lead-cored hard steel arrows with AP tungsten heads. Not bolts, as a cheiroballistra can have the same length draw as a bow--and the same damage-per-strength calculation. No problem at all. Historical note: the cheiroballistras the Romans used had 200gm bolts. Good for hard hitting at range.

Re: Solid metal crossbow-bolts
More people chiming in, well I already drew up the stats I wanted, they made sense enough to me.
The 6d thrust comes from my scaling for thrust damage, then I just add weapon modifiers on top. It being 40x draw weight stemming from how KYOS ST 26 has 40 times the BL of KYOS ST 10. This bow will also be a long one, and might shoot full sized arrows if that helps at all. The arrow being propelled faster than a normal bowstring is in some ways a handwave from using UT materials, 2x velocity of normal bowstrings seemed fine to us. Thank you all for further comments, I am already making this thing and decided what it should do based on prior ideas but this is still nice to know. |
