No way to tell you that, even if you knew the exact case capacity of each one.
Military 7.62 brass is usually heavier, and of less capacity.
But not always.
But to my knowledge there is no exact rule on how much less powder it takes to get the same results.
You just have to spend powder, primers & bullets testing loads to find out in your rifles barrel & chamber.
When changing any component within the load, I was taught to start at the beginning again. Start low and work your way up again. No need to start at anything less than the minimum. Just start their and you'll be good.
