Allen: I'll bet they took too much of the overtravel out, and you're right; set too light, I'll bet....
Not giving advise, just suggestion, but for 25-30 years my gun maintenance kit on any trip includes a screwdriver kit and 2 small wrenches to fix/adjust a M70 trigger, just in case.
I have never had to use it on any of my rifles,but used it once to fix my guides rifle when someone adjusted the trigger and too TOO much of the overtravel out of it.It has worked great for him since.
