Gunsmithing / Measuring mainspring strength
« Last post by Navy Six on March 21, 2024, 11:13:33 AM »I intend to conduct a series of tests on Colt style percussion pistols in regards to mainspring strength and its affect on percussion cap performance. I would like to accurately measure and compare a variety of mainsprings. I do have a trigger pull gauge and considered measuring that as I swapped out different mainsprings on the same gun. Is there a better way of doing this? I don't want my results to be based on "well, this spring feels heavier than that one". Any thoughts would be appreciated.
