My sister in-law just dropped off a box an a half winchester 9mm. Her new boyfriend gave it to her to give to me saying he no longer owned a 9mm. The ammo in the full box is fine, no cracks, mold, etc. The half filled boxed is a mess. The ammo is covered in mold. Apparently this is the ammo he kept in magazine for X number of years. How do I get rid of the mold covered ammo? I am thinking of just drilling a hole into each case and dumping out the powder.
