So, I'm clearly ignorant on the topic, but I'm a nice guy, willing to learn and happy to thank anyone that offers to help... having said that:

Received my Mcmillan drop in for my Win M70 this week, and the action screws/bolts are a bit long... have read on different forums to "just grind them down" but I have no idea how to do so, and concerned about poking up the threads, etc... have read a few online threads on the topic and have no idea where to go from here. Happy to take it to a gunsmith but they have become few and far between and I can't imagine it would be very high on the list of projects for them to complete.

Thank you in advance for your time.
 
find a nut to fit the bolt, spin the nut up the bolt then put bolt in a drill. go to the bench grinder and grind slow, at the same time spin the drill. after you think it's right length remove the nut.
 
I have a fancy tool that is a cone shaped cutter for cleaning up the end of the threads that have been ground or cut off.

In a few regards the techniques described by Troy Fairweather and coltpythonelite can be better because more of the threads are left intact.
 
You might consider not cutting the original screws. Should you ever decide to put the original stock back on you have the original screws. I believe replacement screws are available from places like Midway USA, Brownells, or the manufacturer for that matter. You could keep the original screws with the original stock so they don’t get misplaced, which is my MO...

I like this idea, and do recommend that the slotted screws be replaced with, first...torx head screws and then second, hex socket head screws. If you still want to shorten your factory provided screws, at least consider a hollow-ground driver bit that fits the slots "like a ducks foot in mud".
 
Another thing to consider for your new stock, replacement screws from Brownells. They have, and may still have, a set of three screws for the Winchester Model 70 that are of the same type as used over the years.
