My FMJ bullets designed for a 9mm are sized .355, the same weight cast bullet may be as large as .358. If I tried to push a .358 FMJ down the barrel you bet, pressure would go up. DR"To me the physics of it would indicate that a jacketed bullet is harder to push down a barrel than cast / plated so pressure curves are going to be different, possibly significantly."
That was my main concern. I am guessing the difference in friction may not be that great.
