So what can be causing it? Well, this afternoon I decided to have a closer look at the Mauser. Firstly I attempted to clean and polish the bore a bit because its groups opened up yesterday. Anyway, I checked the bedding. It's free floated but the skinny fore-end was touching the barrel on one side. That can't help accuracy.
So why would it have shot well last Sunday? And the Sunday two weeks before? Well, the previous two days were warm and sunny and the sun was shining on the barrel. Yesterday it was cool weather although still sunny earlier but not so much when I brought the Mauser out. Is temperature causing the stock to contact or press harder on the barrel? What does the sun shining on one side of the barrel do? I think I've asked that question before. And I've mentioned the group opening up after a damaged and difficult to chamber round. The Mauser is spoiling me by the way. That thing is so slick and easy to operate! And what a trigger!
Anyway, just more questions with no answers (yet).
