Lee 308 bullets

Hello everyone, iv been casting and loading 357 for a while now and im considering getting into casting for my 308. Is it worth the effort for a rifle cartridge like this? If i can be around 2 moa at 100m with my savage axis id be happy, is that expecting to much? I want to go lee for the mold because they are alot easier for me to find here than lyman or even rcbs (if they still make molds) Thanks!
