First off, what are “set triggers”? Set triggers are a firing mechanism that releases a rifle’s sear while allowing for a light trigger release without undue wear to the rifle’s sear surfaces. Set triggers make it relatively easy to adjust a trigger pull up or down, depending upon the rifleman’s preference. Set triggers also make possible a lighter trigger release, which in turn, means lessened disturbance to the rifle when the trigger releases.
Set triggers come in many forms. There are single and double-lever set triggers, single-set triggers, close-coupled set triggers as well as four-lever (or more) set triggers.
Single-lever set triggers must be “set” and then tripped to disengage the rifle’s sear. Double-lever set triggers allow the forward trigger to disengage the sear by itself, without being “set”, generally providing a heavier trigger pull. A single-set trigger is obviously one trigger that has to be “set” by pushing forward, then released by being pulled backward. Close-coupled double-set triggers have a rear trigger that sets the mechanism by being pushed forward, then the front trigger is pulled rearward to release. Winchester manufactured many of the close-coupled double-set triggers that we see on vintage rifles, although there are a few gunsmiths today that build them. Many vintage German and Swiss single-shot rifles were fit with complicated four-lever set triggers that gave the advantage of incredibly light and uniform trigger releases. These triggers internally resemble a watch with all their closely fit parts and are masterpieces of workmanship.

ON HUNTING AND SNIPING
Long-range target shooting here in the U.S. has become increasingly popular, at least since the first International Match with the Irish team in 1874.
The Hide Hunting Exploits of HARRY “SAM” YOUNG
It’s difficult now to remember exactly where I first read or heard about Hard Knocks by Harry “Sam” Young. The book is an extremely entertaining read and in the Publisher’s Note, it specifically states, “The great lesson of this book is that “truth is stranger than fiction.”

The Eprouvette
We are all aware of the modern technology to quantify gunpowder performance such as chronographs and pressure transducers, but have you ever thought about how black powder performance and quality control were measured before our current technology was available?
The Ideal Match
In February 1903, the National Board of the Promotion of Rifle Practice directed that the first National Trophy Match would be fired at Sea Girt, New Jersey, in September of that year. A paltry 15 teams were mustered to compete.
