Recipes and max loads should be worked up even when following all the components in a published load. Long ago I wanted to see if there was a difference in brands of .223 brass. One brand the powder was literally pouring out the case while in another brand of brass the powder was at the neck/ shoulder junction. Different manufacturers have different wall thicknesses thus different internal capacity.

Minimum loads should be safe to substitute brass, primers, different brand of bullets, etc.
