@wraith I have changed your original post for you so it makes a semblance of sense, 'heads' are part of the cartridge so don't deform (hopefully). Bullets are designed to expand in different ways, ballistic tips are not designed to make bullets explode, they are designed to increase the BC, to make the bullet more slippery as it passes through the atmosphere and keep up the velocity over distance. Velocity + weight coming to a sudden stop = terminal energy. Bullets are designed by large, very experienced companies, they deform in a predictable way. Understanding that the correct technical term is 'bullet' would be a good start.
With regards to the rest of what you are trying to say .... i'm at a loss. The Ruger .204 is a Varmint round, don't use it, or encourage others to use it on deer.
