I think they represent the last of the pre Beretta sakos that were built to a specification not a cost. I have had 2 and still have the last. There appears to be no short cuts with the build, legendary all steel magazine, ability to top load, just generally built like a brick outhouse. My suspicion is that you’d need to spend many thousands to buy a rifle of equivalent quality from new. That isn’t to say a Browning or a Howa won’t shoot as well (although I doubt they are as consistent), however I doubt they’ll be sought after in 20 years by a rifle smith.
Disadvantages are age, which means they are likely to be well used and a dwindling list of extras-McMillan pulling the 75 inlet was a real body blow. I have just ordered a SSS stock for my 591 so may be in a better position to evaluate alternative options when it arrives! I have never got the obsession with rails on a stalking rifle…hampers the top loading, not necessary for a pure stalker which the sako most certainly is.
A nice clean 75 still takes some beating despite this IMO. Maybe a T3 makes more sense but I doubt anyone regrets buying a 75.
