Kenyon 40x trigger

You can do a Kenyon style conversion to Win 52, by drilling a new pivot in the trigger, just about 3/8" higher than the existing trigger pivot. But you need a carbide drill, drill gently right through both the trigger and housing, while keeping the trigger immobile with the existing pivot in place. Got my pulse rate up a bit, doing this on my CMP 52D... Gets you about a 2-5 oz pull, with barely discernible creep. Butch Hongisto used to do this, might still do them.
