There is a large variety of different projectiles that Precision Rifle http://www.prbullet.com/offers. It is my understanding that the ones without the poly tip would be considered purel lead, and there for would be legal for you.

When I first got my Black Diamond XR I bought some of the Silver Lightning 300 grains and they shot excellent out of my rifle. As I remember Lone Wolf suggestedthem to me and he was right on the money there. The only reason I stopped using them is pure lead is not required here, and I could shoot cheaper projectiles...
