I think you'll find that local for sale ads will garner the best return on time/investment/etc.
I'd browse around to get a feel for the prices. But the stuff you listed is probably quite common. Maybe a buck or two for instance. Maybe less.
I'd go straight to armslist.com, place an add for cash or trade - trade will generally garner a better return. Even craigslist, although it's technically banned, always has people looking to barter services and stuff for ammo. Trading has frankly garnered a great deal of good trades in my experience. For instance, the house I bought had a large extra beam in the garage left by the builders. I had zero use for it and it was in the way. I placed an ad, and some guy traded me hundreds of dollars in ammo for it. We were both quite happy!
Figure out something you want/need - maybe some tools, handyman services, equipment, carpentry services, etc. I bet you will get a great return on the trade value for ammo, which is always in demand.
I wouldn't bother selling ammunition for shipping. I recently sold about $200-300 in ammo online and had to ship it across country. It took me an afternoon driving around to various places to learn that shipping was such a PITA and expensive that I won't bother doing it again. I think I ended up learning that I could not ship it USPS. FedEx acted liked I had a bomb and practically threw me out of the small store, sending me to a different FedEx location which said they could not handle it, and I finally when to UPS and after completing the paperwork and standing in line, it was not time well-spent. For most people, it's simply too big a hassle.
Find a decently acceptable price, list it local. It'll sell.
