I recently purchased some ammo in cans. I would like to know what it is. The owner of the shop said it was British supplus but he was unsure of the bullet weight. On the right side of the can it says..........900 ROUNDS 5.56MM BALL L2A2 and then under that it says 10 in CHR 150 in BDR L4A1. Under that it has ADAC NO 11903-02 and under that UN SER NO 0012    RG.28.7.92..................... On the other side it has CARTRIDGES FOR WEAPONS and then a circle with a U over an N inside the circle.  After that the no. 4A1/Y19/S/90/GB/0355. On the end of the can it has some numbers stincelled in but I can not read all of them. The ammo came on stripper clips of 10 with 3 clips to a pouch and 150 rounds in a nylon pack, 5 compartments to the nylon belt or whatever it is. I have fired about 200 rounds of this stuff with 0 problems. The owner of the shop says he can not get any more. Thank You for any info on this ammo.

I am not a ammo expert but I would start by seeing if the bullet attracts a magnet and work from there.  There are a lot of people with great knowledge on ammo & I am quite sure you will know before the day is over.  Try the magnet first though.  

Thanks, I believe the 28.7.92 stands for the date maybe, other than that I am clueless.

Google it.  It soounds like British.  

I’m betting its “Radway Green”

If so it’s a 63 grain bullet with a partially steel core. The Brits didn’t paint the tips of their SS109 ammo like we do.

Thuban, I think you are right, This looks just like what I have. The only thing is I got 900 rounds to the can instead of the 720 Wideners is advertising. Oh, and I paid more for it. Oh well, it shoots good. Thanks a lot for the help.

The only way to be sure is to fire a round into a pillow and weigh it.

It's Radway Green SS109.  I'm not 100% on the weight.  It's 62 of 63 grain.  The stuff shoots great IMHO.  Never had a problem with '92 can.

Mine came in a poorly painted brown can with yellow lettering.  Ammo on strippers with nylon bandoleers.

Vegas1037. mine looks like what you describe as far as the can goes and according to wideners it is 63gr. steel core. In one ad they put it down as 62 but they admit that was a mistake. Thank You all again.

Radway it is
