Bradley,
I have three M700, ADLs. One built in 1968 (long action), one built in the mid-90s (long action), and the last one was a bi-centennial model I got a year ago last August (short action). On the two long action rifles I had a professional, very competent and trustworthy gunsmith I've used for the past 20+ years adjust the triggers. He did a fine job on them, and also went through and cleaned them besides; no problems. He thought if the triggers on an M700 were clean and adjusted properly, they were just fine. I trust his judgment.
The short action M700, the last one I got, I adjusted the trigger myself. There was only ONE allen screw to do the adjusting with (way different from my two earlier rifles), and frankly, I can't remember if I had to turn the screw in, or out (did have to take the action out of the stock). The trigger adjusted easily, and is set at a little over 3.5 lbs. (I don't have a trigger pull guage; close to that anyway). I daubed the set screw with blue loc-tite when I had the trigger adjusted to where I wanted it. The rifle has been just fine at this point in time; hundreds of rounds through it.
The newer/current M700s have a set screw you can adjust without taking the action out of the stock, but I've never heard how that works out for a set pull weight; that one seems very user friendly. Don't know if those are still on the new 700s.
If I ever have an inkling, even slightly, that I have a trigger issue with any of these rifles, I'll just get a Timney for it. It's that simple. I can't imagine trading off any of these rifles, as they've served me very well for a long time.
At this point in time for me, I really don't need any more rifles. But If I think I'd like to try some other caliber to reload for, I'd have no hesitation at all in buying another M700.
Hope this "old guy" opinion sheds a little positive light on an M700; I like all three of mine. One other thing (FWIW); through the years, I've never met anyone, personally, that's told me of a trigger/safety glitch on a Remington rifle they've owned. That includes any second hand stories of shooters/hunters I've known through the years, too.
