I have an old Mossberg Model 640KD 22 Mag bolt action rifle, serial number 1238664. I bought it new way back, maybe in the late 1960's or 1970's. The trigger pull on this gun is lengthy and heavy. Can the trigger pull be lightened, improved, smoothed out? Is this something I can do myself? I have never had a trigger apart before but it doesn't seem like there would be a lot to it.
Thanks for any info.
Dave
