If you read a little more, I asked the question just as a want to know basis. What is needed to push bullets down the bore? I do see no point in pushing bullets in absolute minimum velocities, but it is just one of those interesting things that get people to thinking. Its how great things were done in the firearm world, asking questions, finding out what can be done, experimenting to see what happens when certain components are put to certain tests. Its called science, something that interests a lot of people, you obviously don't seem to be one of those. In my other thread, I am asking about reduced loads, NOT absolute minimums.

My reasoning is this. I like to know my rifle, how it shoots, how it handles, how to carry it in the field under certain conditions, see how it points and shoots in certain positions, but I don't want to spend tons of money popping jackrabbits and coyotes. I am talking pushing a cheap bullet in the neighborhood of like 1700 fps or so. I can shoot cheap, and get all the practice in the world in one summer, and not go broke doing it. Also, the lower recoil loads of PROVEN safe loads are easier to shoot and help in getting a feel for the rifle without developing a flinch.
