Are you going to say that the shrink/unshrink spells don’t conserve energy and/or momentum and were originally made to conserve the movement vector?
If it is full mass, you not only need to have more STR to hold a gun with the bullet in it, you also need a gun made of better materials and more gunpowder to propel it to a significant speed.
If mass is reduced, normally, one of momentum/energy is expected to be conserved (I haven’t read the DnD manual, so going by physics) and in both these cases, you see the fast bullet converted to a slow cannonball which doesn’t even reach the target.
To fix this, you should at least require a metamagic to change the shrink/unshrink spell to conserve the movement vector on activation/deactivation
Weight of a shrunk item is approximately its original weight multiplied by 0.00025 (or 1/4000th if you prefer fractions) of the original weight.
Shrink item doesn’t affect the movement of the item, so it would retain the same velocity, it would just be bigger. There is precedent for this in, for example, the reduce person spell, which shrinks a person and all their equipment, but as soon as an item leaves the possession of the shrunken person, it expands to full size (but does not become less accurate or have its range altered in any way).
However that did remind me of one thing. It wouldn’t work with a projectile weapon. With a projectile weapon, it deals damage based on the weapon that fired it. A thrown weapon would deal damage based on its size at impact. Funny little quirk there.
I have a few questions now.
