Rem International
Fred,
It depends on which model International you are referring to. The original triggers were made by Hart for Remington as Peter suggested. Midstream (around 64 or so) Remington changed the design and used the standard 40X/700 housing and some common parts with an altered sear and an added third lever.
The original is adjusted as Peter noted except Remington suggested the middle screw, WOP, be adjusted for positive return to forward position. CCW for lighter pull.
The second style made by Remington or those altered to 2 oz standard triggers are adjusted the same as a common 40-X or 700.
