Jim, I fell into this fad and it was at the time when the gunsmiths began using the steep shoulders. I bought a 25-06 Mashburn with a 30 degree shoulder and load data was furnished with the rifle. I thought nothing about flattened primers and short case life and wasn't smart enough to reduce the powder charges. A case would only last about three rounds and when I sized cases about every third case would have a split neck or a hole burned in the neck. I was a Jack O'Connor fan and believed in dumping in a stiff charge of military surplus 4831. Safety in reloading was never discussed. Later Remington came out with the standard 25-06 and I had a new barrel put on the rifle with the standard chamber. I liked it a whole lot better. I know all about this "overloading scheme" and it was pushed by the gunsmiths.
