My players have noticed that astral barriers can't pass through astral beings so they've decided to see what happens if they put a ward on a bullet and shoot it at an astral being.

I've going to have the astral being take damage from the ward as if in astral combat with it. The real question is with dual natured biengs/ astral precieving ones. Which should interact first? The astral body with the ward or the bullet with the flesh? I'm leaning towards bullet with the flesh and treating astral persieving beings/dual natured beings as a similar difference as between night vision and normal vision.

Any opinions?

The rules for forced combat exist only when an astr9ally active entity is squeezed between a ward and a hard place. One example is the shifter in an elevator, the meat can't stop, so the astral has to fight.

The warded bullet will do nothing to a purely astral target, it can just move out of the way.

As for your question, define whether the ward is larger than the bullet. If it is, the astral combat test goes first, and if the critter wins that test, the bullet drops.

Well, it doesn't work that way.

But even if it did, shooting a solid astral entity at another would not hurt. Real bullets hurt cause they damage tissue. Astral entities have no tissue. A warded bullet wouldn't do anything. Kinda like shooting a water bullet at a lake.

err i dont think you canward a bullet as its suppose to find its size from the room your in or there about. now a astral barrier spell hooked up to a bullet is a totaly diffrent story (it makes me think about hte old sr2 thread about magic bullets when anchoring wasnt a mundane triggable form of spell lock)...
