Mr. Edward J. Yost (1923 - 1990)
After accumulating a lifetime of shooting experiences, Ed Yost spent almost 10 years painstakingly developed his single shot falling block Schuetzen action in his home workshop. Thousands upon thousands of hours were spent in testing, trial and error, and improvements, until finally, in the end, every thing was good. Ed initially made a small batch of actions, with only a handful sold locally. His long range goal was to build a manufacturing business to bring his wonderful creations to the market place. But sadly, it was not to be.

Through Ed Yost's dedicated development,
the Yost action was born.

Ed Yost designed and built over 25 manufacturing fixtures.
Ed spent thousands of hours designing and machining the fixtures
Ed's mould patterns and casting blocks for the Yost action.
Ed hand made the hundreds of intricate parts required for his actions.
Ed Yost's original moulds were precision machined and aligned for production.
