The 6.5 creed is just more forgiving regardless of the rifle it's chambered in imo. That said, I would keep the Bergara, probably a better candidate for a prefit barrel if you want to change things up at some point.
It's just one of the barriers of entry. Buy a bivy set-up and go camping over the summer to dial it in and get used to sleeping in the woods. I hear melatonin works to calm the nerves too.
