If you have a gun range nearby, see if they have a "for sale" message board. It seems every range i go to has a cork board with private parties selling guns and what not. Magtech seems to be decent stuff and .38 special is the most common caliber for revolvers. You will easily find somebody that is willing to give you cash for that ammo. Just be fair with the price considering your investment. Many people enjoy shooting but our current political climate has made hording and ammo flipping all to common.
There is nothing worse then going to buy ammo and seeing empty shelves or hearing about the flippers buying every box in the case only to sell if for double elsewhere. It creates a non-existent shortage in perpetuity. If you have that happen a handful of times, it makes you not want to shoot what you have and starts to paralyze people.
Selling at the gun range will get that ammo into the hands of an actual shooter and not somebody looking to make double. The buyer will appreciate it and maybe let you shoot his gun! Sounds like a win-win to me
