At times, the theory of accuracy gets absolutely ridiculous......
Just send me a PM with a FAX number, and I'll forward to you some targets that I have produced with various rifles in 270 Win., 300 Win., 338 Win., 375H&H, and 416 Rem. Mag. rifles that were built on Model 70 actions, and by all means take them to your riflesmith and get his reaction.
I think you'll find that, in practical terms, for a hunting-weight rifle, that a Model 70 shoots just as well the Model 700, and it feeds and otherwise functions much better. If you're hunting pocket gophers, statistical theories, or benchrest titles then the Model 700 holds a slight edge. But if you look at the historical record of the Model 70 in the arena of high-power shooting, including the prestigious 1,000 Wimbleton title, then you'll see that the Model 70 is at least accurate enough to shoot barn walls with when you're shooting from the inside out through the north stall..............
Quite honestly, I've owned some 90 Remington 700s over the years, and well over 100 Model 70s, and I've had many precise, accuracy-oriented hunting rifles built on both actions, including "famous-maker" 'beanfield' rifles, Coues deer rifles, etc., etc. The real, fundamental, nuts & bolts accuracy differences had more to do with the quality of individual barrels and the skill of the makers themselves than it had to do with anything else, and in many cases, the Model 70s have shot better, because they were built by better makers.
Beware of this: Lots of so-called "custom" riflesmiths prefer Model 700s simply because they're easier to work on (sometimes, all they do is screw on a barrel and bolt the metalwork into a stock); the nuances of the Model 70 escape them, and so they masque their lack of skill and experience behind the old "benchrest-accuracy" hokum. So all too often, what gets pronounced is mostly theory, and the rest is ignorance and exaggeration.
I've listened to all of it before, been there, lived it, shot it, bought it, sold it, and got up and did it all over again, and end the end of the day, for my own use, I'll take a Model 70 that's been done-up by a top riflemaker any time...........
