I started loading in 2000 with gentle assistance from the alum of shooters.com
My initial loads:
44 Mag
357 Mag
30-06
45 ACP
223 Rem
What I've added over the past two decades:
30-30 WCF
308 WIN
35 Whelen
9X19
7.62X54R
25-06
8X57 Mauser
7.5X54 (MAS 36)
7mm-08
. . . not all that extensive a list, but keeps me busy enough. I can say that I've not shot a factory round at a deer in over two decades.
I started bullet casting about midway through. My initial goal was to cast for all the 35-cals, both pistol and rifle. I now cast for everything except some of the deer rifles.
