It's really easy and the M-70 trigger design is a very good one. This video gives the basic idea. I wouldn't do the dremel trick he mentions, though.Who does the best Winchester model 70 trigger job around ? (Not moa trigger)
Which after market trigger go you prefer ?To do it I would need the complete rifle in the shop. Considering shipping costs an after market trigger would be the best option.
The video is very basic and I wouldn’t get near the trigger with a dremel tool ! He’s correct about the roughness of the sears. A hard stone in the direction of the sear travel is what you need. Used a sharpie to color the sear and assemble the trigger and work it a half dozen times to see the contact area. Stone the contact are and repeat until you get at least 65% contact. With patience I can usually get over 85% contact. With more contact you distribute the spring pressure better. That gives a lighter trigger that will hold well. The fine scratches going all in the direction of travel also helps with weight and smoothness. Do not rock the stone ! Keep it in existing plane to not round off the edges. If you pay a little attention it’s not hard to do at all.It's really easy and the M-70 trigger design is a very good one. This video gives the basic idea.

A long time ago I did my own on a M70 Match Rifle and shot it across-the-course and long-range for along time and it was a good reliable trigger. Ultimately, I bought a Jewell and wish I had done that many years earlier - no comparison!It's really easy and the M-70 trigger design is a very good one. This video gives the basic idea.
