I was thinking more of a powder bag on the tip that would pop on impact. Nice "explosion" effect

Thats a cool thought to

:lol: made one last summer, worked too well and flied away to the Atlantic ocean :roll: (I was launching it in a park near the beach). So imagine, a 100g projectile falling down from 100m high, and hit a person in the head :lol:

Would it weight that much when all the water was out.

You could ...

Here's a few pics as requested of the other rifle I mentioned. Same principles only with a spring loaded trigger held by a sear, and a soda bottle air chamber.

As you'd guess, the spring loaded trigger does improve the power.

Thanks again for the comments/suggestions.
