I've read that hard cast bullets are recommended for heavy/magnum (fast fps) loads i.e. Brinell 18;
and that softer lead bullets are for slower/lighter loads i.e. Brinell 12.
The reasoning is because the softer bullets will obdurate (fill/seal the chambers/barrel) at the slower speeds; while the harder bullets will obdurate at magnum-type velocities.
My question is: What is the down-side of using the softer bullets at magnum speeds? Is it merely "more leading" to clean out...????
THANKS,
