I just started about a month ago but so far:

Pistol:
9mm
40 S&W

Rifle:
30-40 Krag

.308
.270 Rem
.223 Rem

Some ridiculously large amount I can't even keep count of now and I've reduced it over the last few years. I know I have several of those red boxes that hold multiple dies. I have more bullet molds than most folks own in dies.

One at a time...

Anymore only the 7x64, 358 NM, 30-06, 30-40 Krag.
