(With the longer sling I could not feel the 30g ammo and was not able to fire it properly)
This is something NOOC can talk on. He's been using a weighted pouch to sling very light ammo and, from what I've understood, has found it to be quite successful. Throwing very light ammo can often be far harder than very heavy ammo.
Thanks Kick! Here’s my engineer/physicist answer: The sling makes it easier to transfer power from your body to the ammo. Power transfer to light ammo is more difficult, and a longer sling doesn’t actually help much if the pouch is too light because wind resistance eats up all the extra energy you put into the longer sling. Adding weight to the pouch is a way of “impedance matching” that allows for increased power transfer to the ammo at the cost of overall efficiency, because a lot of the energy stays with the heavy pouch. You put energy into the sling+pouch. Heavier ammo means more energy goes to the bullet overall, so it’s better to increase the weight of the ammo unless you are specifically trying to throw something light on purpose.
As far as my experience with weighted slings...My backyard only allows about 17 yards max, and some of the ammo I’ve been playing with is under 10g. With a 60g tennis ball the weighted sling feels pretty weak... which simulates a longer distance throw... sort of (I think shakli started that discussion). I haven’t tried light weight ammo at longer distances, but I think the best way to do that would be the compound sling if anyone has time to figure out how to throw with one. The timing is still a huge challenge.
