Pressing forward on the lever alongside the barrel of your Snowblunderbuss stretches a spring.
As you press the tip of your Snowblunderbuss rifle into the freshly deposited powder of snow the spring oscillates an aluminum/ium bowl, with an hydrophobic coating and spins a perfect snowball.
Drawing
back on the lever alongside of the barrel creates negative pressure holding the snowball to the bowl until fully retracted up the barrel, while also stretching the slingshot elastics to launch said perfect snowballs at velocities which would make snowball fights more like paintball.

Trying to picture how an oscillating bowl makes a snowball ... |
|
| |
Also, you're trying to use negative pressure to draw the snowball into the muzzle of the weapon, but that would only work if the snow fitted snugly into the bowl, right? And you've made the bowl hydrophobic, so wouldn't that tend to break the seal, and cause the new snowball to just stay on the ground when you lift the blunderbuss? |
|
| |
The negative pressure intake is at the centre of the bowl so hydrophobic be damned the ball will stick. This [link] will show you how to make a perfect snowball with a bowl. |
|
| |
Unless you have some way to actually compress/pack the snow densely into the mold, I suspect you're gonna have a poof of powder in your face as soon as it leaves the barrel upon firing. |
|
| |
You just need two hemispherical scoops mounted on lever arms like tongs. Pulling the lever operates a cycle of extend - close - retract - open so that the scooped up and compressed snow is left on the hydrophobic non-stick slingshot platform ready for rapid ejection. |
|
| |
Some of the parts you need already exist. I've linked a couple of related products. But I don't think they'd work very well with powdery snow. |
|
| |
Even simpler than the scoop thing I linked, I recall a toy that was just a long handle with a hollow space on the end. You'd jam it into the snow, then use overarm swing to throw the "plug" of snow. If I can find a link I'll post it. |
