Many of my rifles have set triggers. My Jaeger has Davis double acting triggers, and yet when I had a poke at a young buck exploding from the trees, I did not have a second thought about them. When I knew something was up, I set the triggers, and when he blasted out, I swung on him and touched her off. But I use my hunting rifle and shot bag a lot on our trail walks, so my hands instinctively go where they need to to get the job done.
I shall install single acting triggers on my own mountain rifle build.
