Can you recover magic/alchemical arrows?

Interesting.  I'd always assumed like Abraham.

So, does that make it a 50% breakage and a 50% to find?  Does that also mean that you can recover your regular arrows out of dead creatures until you get a +1 bow and then they all explode when they hit the enemy?

Also, who's buying magic ammo?

Some of us do buy magic ammo, because they don't make slaying bows.  The 50% assumes find and broken. 

And no, it is only for enchanted ammunition.  Ammo inherits the bonuses of the weapon firing it, but only if the ammo
doesn't have a better enchantment.

Things like holy on the bow and things like bane on the arrow stack.  For enhancement bonuses you use whichever is higher, 
the bow or the ammo.
