Sizing bullets

[bruce moulds]

sam,
if your 411 bullets will fit in a fired case, you might be wasting your time sizing them to 408.
this is because there is a high probability that they bump up
to whatever size the internal obturated case measures when you light the fire and before they move.
you are really doing work for nothing.
smokeless is a different deal.
all that sizing down and sizing back up cannot be beneficial to accuracy.
a lot of people prefer to fill the case with alloy for best results. if this requires a bigger bullet, then the chamber is too big, or the brass too thin.
keep safe,
bruce.
