I installed set triggers on an old Oberndorf action and I still have a swap barrel Model 66 Mauser with set triggers I bought in Berlin in the '70s. I also have them on my '74 Sharps. I like them, and enjoy shooting them, but I think it is more of an aesthetic issue with me rather than utilitarian. I hope this is not a naive comment but I was always under the impression that set triggers were developed to cope with the metallurgy of the day. By that I mean set triggers were popular on cartridge rifles in a day that metallurgy made it difficult to make a gun with sear contact that would hold a light trigger pull over thousands of rounds in a guns life time. With set triggers a substantial sear engagement could be realized while still having a very light trigger pull. As metallurgy improved, rifles could be manufactured with trigger and striker/hammer sears that had far less engagement which could result in crisper/lighter trigger pulls. I think this may be the root of JDS's claim that a single, well adjusted trigger can be more accurate that double sets. If the sear contact on a double set equipped rifle is substantial, I can visualize a rifle's point of aim being upset (ever so slightly) when the kickoff wacks the sear extension. People talk about the harmonics of barrels and the impact on accuracy...how about the harmonics of the double set kickoff. Terry H.
