These are for my 1945 Nagant.. Is the one with the grey a tracer bullet??

No, that silver paint designates a mild steel core. Not allowed on many ranges so check first. Also, these are corrosive so clean the gun well after use. A lot of this surplus ammo is coming on the market. Most were produced in the 1950s-70s.

Vern,, thanks much! Mild steel core,,must have fragmented everywhere [?]...

Andy gave me a mint Russian 1945 Nagant for my birthday years ago . He had a house in the country and I went up there to site it in. He gave me boxes of both kinds of ammo... We shot probably 10 different guns that day and Many rounds...The Nagant was pretty reliable and acurate..

* So,, when do you know if its a tracer??

The rifle isn't worth much [I don't think].. I am VERY tempted to 'sporterize' it for hunting....Its a super heavy thing. I have some ideas to lighten it.. One I already did was take the folding bayo off. Might take down/off some of the fittings , wood etc. ...

Color codes are different depending on the country of origin. For WW2 USSR the colors were Red - Incendiary, Green - Tracer, Black - Armor Piercing, Black/Red - Armor Piercing Incendiary, Violet or Violet/Red - Armor Piercing Incendiary Tracer, Silver - Mild Steel Core. Warsaw Pact and post WW2 USSR Ammo added Yellow - Heavy Ball, Black/Green - Low Velocity, and replaced Black/Red with Black/Yellow for Armor Piercing Incendiary

, WOW,,,ok,,,so these colors would be on the bullet itself... Vern, thanks much.... IF I could get it lighter I think it would make a good deer / personal long range rifle..

I wouldn't use ammo that old. Better to leave them as on the shelf and use the newer, workable ones.
