Walker Set Trigger Patent:

DuPont required all engineers to keep 'notebooks' so complete one guy can take the other's job. Walker's stack is several thousand pages of scribbled math and geometry and notes, mostly to do with the Model 721 and the .222Remington. It is more a diary while creating and running the custom shop, it is a very good guided of what's important to accuracy.
I've said several times it would make a great book, but what he found is now 'common knowledge' and shows in every rifle match. The 40X was the first rifle to give an accuracy guarantee. HE knew how to make a rifle shoot well and it started with the action.
The .222 research is very enlightening as to his ideas based on many years of BR competition and access to every ballistics lab and test range a designer could want.
He tested MANY rifles in the vibration test. He tested rigidity of actions with rails as opposed to tubular actions. He did all the test and many of the results is seen in Remington rifles. BTW-- The 1950 Model 70's trigger was the 'quietest' of all but the direct acting Mauser types are close behind. All those studies are in black and white and presumably publicly available since their release in Dec. 2014. Fifty cents a page for a case file with half million pages of exhibits restrains curious researchers, but I can give the case the information was released for.
Why did I get paid to read the notebooks of four engineers? Trying to find the actual 'use' of the Walker trigger connector. I have his testimony (2 vol) but a company man to the last....at 104 years old.
I've seen those trigger machines/plotters work dozens of times. It shows geometry is extremely important to a safe trigger. Exact geometry is too expensive for gun companies to accomplish within budget. Canjar made his own graphic trigger analyzer using a spinning disk and stylus.
I'm with pudfark-- It was a throw away remark meant to encourage critical thinking. It did that. Minutia of trigger pull as about #104 of things to consider for a better group.
I've seen several prototypes of the Walker set trigger and the parts of one in a bag. Notice they produced the 2 oz whichthe Germans invented Bob Hart invented. It is what became the Remington 2 Oz. It has less vibration.

Time is still what you make of it. Take that time (which is pretty cheap) and use it to improve your shooting ability no matter what you shoot.
Unmolested, out of the box 700 Sendero SFII in 300RUM at 500 yards. Please discount the .243 Win hole to the right.
Yes, we've spent a lot of time getting to know each other 😁 and time is lots cheaper than anything else, especially fancy widgetry to test lock time, trigger vibration and the cornucopia of other things we blame misses on.
