Is Russian made ammunition authorized?

#CSA Rules regarding ammo on thier ranges cut and pasted from thier website No tracer, armor piercing, steel core ammunition or buckshot is allowed All ammunition in rifle magazines will be inspected 30 caliber is the maximum allowed for rifles All center fire rifles must be shot at maximum distance All center fire ammunition must be jacketed, except for 22 caliber rimfire or slugs

I have over 400 round of 7.62x39 and 54R I brought with me when I moved and have been trying to find a spot I can shoot them.

I used it there but they did inspect it. 9mm

Advanced Guard: I didn't ask about Russian ammo but if you're thinking about bringing anything but FMJ with brass casings, I wouldn't.
