A friend of a friend gave me a large box of opened ammo. This stuff looks old. I am looking for help to identify these two rounds. First is the .45 round, it looks like lead but when pressed in the vice it looks like FMJ with a gray color? You ca see the crack where the jacket broke and it has a copper color, and the lead tried to squeeze out the bottom. They mic at .450. The markings on the head are REM-UMC 18. Most of them were in a 3 round moon clip looking thing The second one is a rifle round. There are 180 of these and I would like to know what they are before I melt the lead down. The head stamp is FA 37 and written on the boxes is 2225. These rounds are lead with gas checks.
