Did a trigger job on my 336. remove the sear and very gently remove the burrs and machine marks from the engagement end with a medium stone then finish with some 2000 grit,it only takes a little go easy. Cut one coil off the hammer spring. Perform a "bump test" bring to full cock and tap tap the butt on the floor to make sure it doesn`t slip. My trigger went from 7 1/2 down to 3 pounds. nice & crisp. DISCLAIMER. Do not attempt this if your not confident, take to a gunsmith or buy a trigger happy kit.
