All I know is what I read in old gunzines, but Rocky Gibbs had recommendations on what brass to use for his cartridges. I recall he had it refined down to the lot numbers of military match that he considered superior.
Lacking Quickload and Pressure Trace, he said that a maximum load should leave primer pockets tight for ten loadings. One gunzine author is happy with five.
In the 1980s, custom gunsmiths made a number of fancy hunting rifles on 1909 Argentine Mauser actions. Peacetime production of very good quality, they even had the sporter style floorplate latch in the trigger guard.
A popular chamber was .280 Rem. because
a. 7mm bullets were in fashion and
b. its standard case diameter meant the gunsmith did not have to alter the bolt face and magazine lips, leaving more of his time and your money for styling features.
It was also claimed that the .280 was the equal of 7mm Rem Mag "with bullets less than 150 grains." Actually, of course, that was a substantial overload, which some of the experts dealt with by forming Winchester brand .270 brass to .280 because they considered it harder and stronger than Remington brand.
