223 Rem Practice Question

Hi Fella’s

i came accross a few colorfull plactic 223 Rem rounds with a PCA headstamp. Any idea who made them and what country they were from? I have a red. blue, gray, and olive green. Most of the body is platic. The heads are brass. One is open point and the green plastic one has a green tip.

Thanks in advance, joe
