i don't recall guns review being overtly biased in its reviewing - though interestingly they did test the firearms reviewed both on the range and, in the case of sporting rifles, in the field: So a .308 might be taken out at hinds, for example.
That was a proper, all-round shooting-sports magazine with regular pieces on law, target-rifle, clays, game shooting, stalking and equipment reviews as well as bits of history and stuff on artillery, bayonets at other less main-stream fodder.
But where is it now?
