Using the same gun and same bullet to reach a stated velocity, would the pressure be the same for different powders. I am not asking about the amount of powder.
Where I am going with this is a Trapdoor 45-70 using a 405 grn bullet trying to get 1350 ft/sec. Using say 25 grns of one powder and 30 of another whould the pressure be the same. Now I know the powder has to be for the 45-70.
