I've never owned a Pre-64, but did look for a nice one for years with not much success. Every single one I found looked like it had been trough a couple of wars and then some, but because it was a pre-64, they were priced the same as better brand new rifles. So, when the new ones came out, i resisted for about, eh... 25 seconds before making it to the store to get one.
Mine is a Featherweight in .308 Win. Out of the box it was not as smooth as any of the pre-64's I've seen over the years, but that is normal. When you buy a brand new gun, its bolt hasn't been operated thousands of times like on an old gun, so it can't be as smooth. But after working a bolt a few hundreds of times, it is now one of the smoothest bolt actions I own.
Fitting on mine is excellent, although I am sure you could find many good examples of the pre-64 model with just as good, or better fitting. The wood on these new models is very nice for a production rifle, including when compared to the pre-64 models. And as a bonus, they come shaped for scope use, whereas the older rifles came with stocks better dimensioned for open sights use.
I am also one of those who wishes they had left the old trigger alone, specially when I am sure they were cheaper to manufacture than the new one. But hey, I guess they needed a marketing gimmick, so we got the new trigger. That being said, after some adjusting (including shortening the trigger return spring) I ended up with a 2.5 lb trigger pull with no take up, no over travel and practically no movement when breaking. By the way, when they say it is an adjustable trigger, they mean you can screw in the trigger weight adjusting screw to make the trigger heavier than the 3.5 lb it comes adjusted to. If you try unscrewing it to make it lighter, nothing happens, because the captive trigger return spring is just too long and won't allow the trigger to get any lighter.
Finally, accuracy. I will just say that the last 6 groups I fired with it (3 shots each) were all sub MOA. Five shot groups do go a little over 1 MOA, but these rifles have light barrels that can warm up quickly and I am not a very patient person to wait for the barrel to cool down between shots.
I would say the new M70's should be considered by anyone looking for a high quality bolt action rifle. I have been wishing for another one myself, a Safari model in .375 H&H. I just hope Santa's a member here.
