BWHAHAHAHAHAHAHA
I'm wondering about the math, weight of the bolt, speed etc.

Tod established in an earlier video about Medieval crossbows that the powerful draw weight but short powerstroke means that the most effective way to increase the energy delivery of a given shot is to increase the mass of the ammunition.

When I was into blowpipes I found the heavier the dart the powerful the impact. The downside was the range degreased and trajectory increased accordingly. At some point I had to reach a compromise. While the lighter bamboo dart CS was pushing was a pleasure to shoot and watch streak to the target it was the heavier bamboo darts that I made that got the job done. I have a photo, best not to show here, of one of those w/#11 Exacto blade penetrating 6”? inches out of the butt end of a ‘possum after travelling the full length of the ‘possum. I could penetrate pigeons with a .44 cal. ball bearing. A .38 cal. would not and a .50 cal. was too heavy to get sufficient range. But the inanimate objects targeted with those were dramatic. I had several, since have forgotten the weight, blunt darts that were lethal due to blunt trauma. The heavier the more effective but I had to be careful of effect vs distance. I had similar experience with archery. Those light aluminium arrows that a friend had that got me interested were nothing like the heavier wood arrows that I ended up using.

I'm in the process of adding more weight to my bolts as well. I hear bike spokes are decent for this

Not bad at penetrating I could hole a tin can and I think get an exit. Not that good to hunt with. My favourite were bamboo with CS cones, and #11 Exacto blades. Many people didn’t have the ability to make them. So I made this video for our forum members to prove that they could fly true. The problem was they are demanding in their construction. The blade up front acts as a sail or wind deflector if you will. The least bit of misalignment will throw the dart off course.

I heard of someone using 1/4" Nylon rope, but I can't get it to fit in the bolt, and am not too confident on removing the piece that the point screws into

If want to continue start a new thread rather than hijacking this one as this could get lengthy and I’ll be glad to help as much as I can. Below is a bicycle dart through a tin can. My camera back then was terrible.
