Thanks Roy.

I don't know if I contaminated the primers as I was using the primer slide built into my Redding press, and feeding that one primer at a time, which is what I always do when reloading for express rifles, since the round count is manageable. But I may have gotten sizing wax/lube on them? Don't know. I have magnum primers here and have used those before. Will switch to those and keep the BR-2s for modern (e.g., smaller) cases.
