I recently purchased my second stevens 200. After reading all the writeups on this forum I decided to lighten up the trigger. Using a digital fish scale to weigh my bottle of water i hung from the trigger i checked 5.4 lbs on the unmodded factory setting. I backed the tension screw a few turns till i was uncomfortable going any further. Slammed the butt a few times to verify it was safe. That resulted in 3.2 lbs. A week later i picked up some 0.043 piano wire and replaced the factory wire. The wierd part is I left the screw where i had previously set it and checked only to find a 4 lb pull. I realize the factory trigger isnt adjustable much lower than 3 lbs. But i was hoping with the lighter wire i could get a few less ounces pull with the screw set tighter. But with the 0.043 i cant back it out enough to get back where i was with the factory wire. Any ideas why?
