The easiest one that I have found to reload accurately is probably the .308 Winchester. I had a hard time getting .243 figured out, but that was mostly due to die settings. Boat Tail bullets will help you out when you first start too, since they aren't so picky about getting started. I enjoy reloading 30-30 winchester too since there are a lot of variations from lead bullets to all the different powders to try in it.
