These came from a few 7.62 NATO rounds l pulled down the other day. US manufactured with primer crimps intact. Heavily corroded cases so the only thing worth same was the bullets. The powder was a fine ball very similar in appearance to WW748 or BLC-2.
 You can barely make out as ring on the hanging bullet so that was the only reason l thought to test them. All are very magnetic but since the one is hanging I'm guessing steel jacketed instead of real ap? 147 grain. |

Probably. I just didn't think US made utilized steel jackets.
Can't say was wasn't hoping for 7.62 AP though.

Gilding metal clad steel jackets. The US stopped manufacturing M-61 AP a long time ago.

Copper clad steel jackets were an "alternate standard" bullet for M80. I read somewhere that up to half of some years' M80 production had these "bimetal" bullets.

Quote HistoryQuoted: Gilding metal clad steel jackets. The US stopped manufacturing M-61 AP a long time ago. A coworker gave me a zip lock baggie with 19 rounds nearly 20 years ago. He found then under his trailer house. I knew then they were only worth the bullet. I just recently found them again. I was hoping....

Cut one open and see if the core is steel - only way to be sure.
I use a .30 and .50 core for a pin punch to dimple metal before drilling. Handy to have in the drill bit box. |

U.S. M-61 AP projectiles have a French (smooth) crimping cannelure unlike the knurled ones in the OP with a knurled identification cannelure above that . No need to cut one open. |
