What is apparent from testing is that penetration stops increasing at impact speeds above about 1250-1300 fps. When the impact speeds significantly surpass about 1600-fps, there is a very definite and measurable decrease in penetration depth. This raises some interesting issues regarding the relationship between kinetic energy generation and impact-effect. Although higher velocity projectiles always generate more kinetic energy they clearly do not produce deeper penetration, and when the velocities reach the levels common to today's magnums, the increases in velocity result in significantly reduced penetration. Simply stated, the faster they strike the faster they stop.

i dont realy want to get into casting bullets, not that i would not enjoy it i would rather buy them from someone who knows what they are doing. from my understanding it is better to shoot a heavier bullet around 1,100 to 1,300 fps than a light bullet 1600 fps. being that the 500s.w. has so much room, i think it can handle a good 500 to 600 gr. bullet without too much preasure. this will help my decision on which cartrige to go with either 475 or 500 linebaugh or the s.w. thanks!
