ID Wolf 7.62x39 Headstamp and Yellow and White Tip

Hi,

Bought both of these at SLICS a few years ago. Both cartridges are lacquered steel cases with red primer seal and both have headstamp “WOLF 7.62x39”. Both bullets are magnetic. One has a yellow tip and one has a white tip.

Does anybody out there know what the colors codes mean if anything? I guess it could have been someone in their garage decorating their ammunition also.

Home reload.

Less home made than most likely a gun show load by C&T or similar companies.
