There's plenty to be said for older rifles especially high quality models. But it's also true that advances in manufacturing have made modern rifles significantly more accurate as a general rule. There were of course accurate rifles many years ago but in my experience they don't match modern rifles.
Anything made in the past 15 years especially has a really good shot at being a MOA rifle right out of the box. That mostly wasn't true of older rifles but of course some were that accurate.
I like old rifles. Don't get me wrong. But for shooting pleasure I will take a newer model every time because I like hitting what I shoot at. Sako, Howa, Weatherby, Savage, CZ, and others make exceptionally accurate rifles now with many of them guaranteed to be MOA rifles. That really doesn't decrease the value of older rifles but not a lot of them were MOA out of the box. Unfortunately modern Remington's are not what they once were according to what I hear. I haven't shot any really good new Remington's but I've shot several that weren't. There are still good Browning and Winchester rifles but they are made by different companies than the ones that made them years ago. A 1942 Targetmaster would almost certainly be more accurate than modern Remington rifles.
