Safe to tumble loaded 22lr?

Got a question. I had a large box with about 700 rounds of 22lr in it dump out all over the ground. To make matters worse I was in a lake bottom where the water was down but still muddy as heck. I threw all the rounds in a few zip lock bags and now I have a bunch of 22lr covered in mud, dirt, and clay.

Can I tumble them clean?

I have done some searching and gotten mixed results on tumbling loaded ammo. I have yet to find anything on tumbling loaded .22lr rimfire. Is it safe? How hard does the rim need to be struck before it goes off? Anything else I need to be aware of?

Thanks

Ive had some 22s get mixed in with my brass in the tumbler.

If you can get one to light off, i think you have done something.
Ive never just tumbled 22s tho. Give it a whirl, just put the tumbler some where safe just incase something happens.

if they got wet they may not shoot. i had some that got wet from a fishing trip and had to shot them in a s/a pistol because most would not go off . so good luck my friend
