Is the Prvi ammo that graf and sons sell the same as the wolf gold line? I know that it is 4.99 a 20/box shipped with a C&R discount. I ordered 500 rounds of it to check it out.

The PRVI ammo as far as I know carries a "NNY" headstamp, and a blob of orange-red paint on the primer.  If I recall from past, thier brass has small flash holes, and primer pins like to get stuck when trying to size the brass,  I toss it anymore.

You might be better to try the ammo forum, or contact Graff direct.

Yes, they make it for Wolf Gold...........they call it XM193 spec. The bullet is exactly the same diameter as Federal XM193 but the copper jacket seems to be a bit softer. Tends to leave slight copper "flashing" on a flash suppressor when a Sound Suppressor is used. But for plain ole plinking or training, it works like a charm. Accurate and goes bang every time. I have run 1000 rounds of it with NO ill effects. Hell, it isn't even dirty. No report on reloading, since i don't.  

I bought some of each in 8mm. This explains why they look exactly the same.
