Hanshi, mine used to be the .243 Win but now its the 7-08 Rem.
As far as bullets go, once this shortage hit I started casting for all my CFs. I figured as long as I was casting for the muzzys I may as well buy some antimony and start casting for the CFs. I case all my pistol bullets, 9mm and .45 and for the rifles, 309", 377", 7mm, and .458"
