RE: Vari-Flame & CCI small rifle primers
After my experience with the Vari-flames, I think it really depends on how the variflame adapters fit in your breech plug. Some people seem to have no problems, others do. My biggest problem was that sometimes the primer wouldn't fire at all - there was a small dent in the primer from the firing pin, but no ignition. I don't think they are a scam, but certainly seem to work better with some rifle designs than others.
