The easiest round I found to load for was the 308 and the 6.5-47 lapua. The one I hear is the easiest is the 6BR. I don’t have one so can’t comment. I hate load work also, I never have the time for it. 3 kids,work, side jobs, and any other responsibility I have. If I had the money Copper Creek here I come.
Those are just my 2 cents for easy ammunition to load for.
Simple answer.. Using berger hybrid bullets the easiest I have ever loaded.. 6.5 gap 4s 6.5 x47 lapua very forgiving cartridges to load for.. Even the 300 win mag with a 215 berger hybrid was easy.. Others have been very finicky and harder to load for.. just my humble thought.
