They are as accurate as any Swedish Mauser. The question is not if they are any good, but what are they good for?
In the '60s the DCRA converted to 7.62 NATO rifles and opened the rules to any rifle. Every bolt action was tried to find the best ones. For a time, No.4 conversions, German Mausers, P'14/Model 1917 and Swedish Carl Gustavs were competitive. Then the CIL/Savages, Remington 40X, South African Musgrave and Australian Sportcos began to open the lead. The winning rifles today don't even resemble the old timers. The open box magazine and large loading area were only two of their weaknesses. That said, there is inherently nothing wrong with the Swedish Mausers, but not if you want to win matches.
A former hunting buddy of mine shoots antelope with a 6.5/.284 conversion. Same old Swedish barrel rechambered and restocked. It is a screamer, and that cartridge has been successful in open courses of fire where it fits the range template.
