Ok, I have been reloading now for about 8 days, so please forgive my ignorance.
I remember from physics class many, many moons ago that every force has an equal and opposite force. So a bullet fired out of a firearm with a certain mass and a certain force, will create a certain amount of froce in the opposite direction it is traveling. Question #1, does cup pressure have anything to do with recoil? If two different powders can be used to make a given bullet leave the barrel with same velocity, will the powder with subtantially more cup pressure create more felt recoil. #2 is the higher cup pressure harder on brass. #3 What should I be considering as far as cup pressure goes.
I am trying to get a handle on why I should choose certain powders over others, intead of just because so and so said it works well for them. It seems obvious to me that fewer grains of powder should be less expensive if the powders cost the same. Clean burning is good. As is the ability to generate an accurate load. Position insensitivity seems important to accuracy. Anything else I should be considering?
