As many here know ; I've shot my M-N in competition for several years now . With the assistance of David Fair at Coyote Creek Armory , Dave Manson of Manson Reamer fame , and of course Ken at RSI , We have developed a Mosin Target Rifle that can stand beside anything out there . But I was still having a issue with "Trigger Pull" , that was causing scoring issues .
No matter what ; I couldn't get my trigger pull below about a pound and a half , and it was hurting my scores , due to pulling the gun "off target" thru the "pull" .
After several visits to the Timney factory here in Phoenix , the trigger was set to it's lowest allowable , of 1-1/4lbs. , but still not enough . After spending some time studying the trigger bar / sear / bolt release , I came to the conclusion that there was only one solution to the problem . Reduce the firing pin spring pressure .
I had several stock F/P springs , so they became my Guinea Pigs . I carefully ground off one coil off of each end of the spring , making sure that the end was flat . Re-assembled the bolt , and off to the Range . It was a improvement , but I could still "FEEL" the trigger bar dragging , as it released the bolt .
One worked , two should be better , so off came the second coil on both ends of the spring . Re-assemble , and back to the Range . Bingo ! A near perfect 200 - 18X at 200 yrds . And the trigger pull was down below 8oz.
SO ; if you have a Timney trigger in your M-N , and you're unhappy with the heavy trigger pull , and inconsistent POI , try this "Mod" , but be careful about a potential "Slam Fire" situation , and make your changes carefully .
