Hovis,
I've been using Russian large rifle dirty primers (PMC brand) for maybe 4 years now in my .308s with good results. The only reservation I have is that they are even more finicky to seat than Federals. I guess that this could be because they have the Euro-style domed cups rather than the defined corners of most primers & probably have a tendency to cup out when a bit of seating pressure is applied.
It doesn't matter at the moment because, as a result of a bit of arthritis in the thumbs, I'm seating primers with the K & M dial seater to ensure some uniformity with the outcome.
As they say, as long as you're still breathing.....
