[BvS] Why did Batman build Kryptonite smoke bombs instead of Kryptonite bullets??

I think the bullets might have been more efficient..

A poisonous bullet can be dodged.
If not dodged it could be pulled out.

The smoke covers a broader area, protects Batman when within it, and when inhaled is harder to remove.

You use poisonous gas on your enemies, you don't throw a frozen chunk of poison at them ;)
