I don't think Bob is saying all lightweight rifles are persnickety. Instead his post is specifically about pre-'64 Model 70 Feathwerweights, especially in their original stocks with no bedding work. This isn't just because of the bedding but because pre-'64 actions weren't as precisely made (as in "blueprinted") as many newer rifles. Plus they had iron sights attached to their barrels, which can also affect accuracy.
That's nothing against the pre-'64 Model 70 Winchester. It was what it was, and the Featherweights I've owned have shot plenty well enough for general big game hunting. But they did NOT shoot like my NULA rifles.
