the bow and crossbow although not the best out there were made in the least amount of time possible with the tools and skills I got. When making a crossbow most people will do it like me and outsource the bow, making a composite or steel crossbow all alone will take many more tools, time and experience than bow or sling making.
These are the first shots with the crossbow, next time it will be upgraded.
The hemp slings and the concrete ammo can be developed further.
The kestros didn't perform well the sun was getting low and got only 2 tries.
The bow performed really well for its low poundage and short length.
The steel bow dimensions: 7.1mm thick, arc 77.7cm, bowstring 75cm, bow mass 1350gram, 4.7gram bowstring, width at middle 5.1cm, width near tips 1.5cm

In this slinging style the sling rotates less than 360 degrees before the release and the pouch is held in the non throwing arm.
while it is not the style to break speed or distance records it has a good rate of fire and speed in the shot. It can be very accurate and consistent.

This is the distance that ancient Romans trained at daily according to de re militari, their targets were consisted of bundles of twigs. My target was consisted of branches, twigs and a metal mesh to support an archery target face. Context is important and cannot fit in a 2 minute video, for more context subscribe and hit the notification bell to not miss it.
Ammo was river stones.

in the distance at around 60 meters you can see an 80cm compound archery target face. I didn't get a hit, the stone had a bad shape and curved
Looking back the ammo is not ideal, I should have used heavier ammo for the hand, some stones were tiny.

limited edition sling.
The generation is how many key changes I did to conclude to this design.
The unique features of this sling are:
• a Very durable Cupped leather pouch that can sling a great variety of ammo shapes
• Sewn 550 paracord that prevents core pretwists and makes loading easier and faster
• Raised leather for a very durable and smooth transition from pouch to release cord
• Acro release from Dyneema and leather for light grip, powerful shots and high durability
• a Leather finger loop for comfort

Slings used are two classic hemp slings (how to make them youtu.be/__NpItACbBo ) and a paracord sling without knot on the release which I was expecting to perform far worse because at longer ranges you might pull a little harder and the release might slip.
Ammo used was river stones and rubble stones found at the field which performed okay.

check my previous video on some ballistics and how to throw these arrows: youtu.be/DuNp9UuKasM?t=204
I threw a lot more times, these are the best clips. The short javelins are very tricky to throw point first, and they don't seem to stay point first after 15m. If you are looking for something fun you should definitely try the arrows.
I forgot to mention the PR throw was 78m with an arrow made from a beech dowel at the dimensions of Yorkshire arrows mentioned in "the Crossbow" by Payne-Gallwey
all short javelins were shorter than 1 meter most were ~60cm

The last shot in the video is probably a hit on the upper edge of the target.
For the close misses watch for a puff of dust at upper left corner of the target.
Haven't been at the long range for a couple of months, the skill is maintained!

This is something I wanted to do for years in fact I was planning to do it for the whole year of 2021 but just the analysis of one month took me more than 100 hours to make (leave a Like for the effort) is it worth it or not?
This is the first time we see something like this on slinging so it is definitely worth it, it helps understand what metrics are useful and what is not, would I do it a second time? ¯\_༼ ಥ ‿ ಥ ༽_/¯ This is useful only if it's automated somehow. The hours spent on collecting data manually could be better spent on slinging. 100+ hours is a lot of time. Leave a comment on what do you think.

My slings were falling apart so I took the opportunity to test different release knots, they weren't properly made though. Heat, sun, wind, ascent all contributed to not performing that well, but that's how you learn, try to focus despite the adversities.
In this video I used gravel-rubble ammo out of necessity. This was the first time after many years of not using gravel-rubble ammo. I was surprised that they can be accurate and they don't destroy the slings as fast as I remembered. Still I wouldn't recommend using this kind of ammo.
