Hi there,
A friend of mine owns one. I went moose hunting with it and 300 Weatherby barrel. Very nice gun indeed. However I din't feel comfortable hunting with such expensive gun - the friend owns de lux something model

(and Swarovski 2.5-10x56 on it

)))))))))))) Eventually I abuse my stuff, so I don't want to be sad about such a nice gun being abused. But there's an 'offroad' model if I remember the name correctly - with syntetic stock.
Two best things about the gun are interchangable barrels and straight pull bolt, which to my surprise no one has mentioned here. The latter greatly reduce time for follow up shots, but read further for more details. The safety and ccocking is tricky, I agree.
Another acquitance took this rifle bear hunting. He injured the bear, it was rolling on the groung for a few secs (375 H&H&

and then it ran away. All this time the guy was trying to recycle the bolt. (You have to push a 'button' to do it, which you don't have to do with regular bolt action.) So if you have some 'normal' guns you may have a problem remembering to push the 'button' on r93.
Important safety feature - the gun may be carried uncocked with cartridge in chamber and you can cock it instanteneously with a push of a thumb.
Friend's gun has 'iron' sights, which is good, but 'iron' is PLASTIC! Would you beleive it? I was told a story about another happy owner of R93 wich put his rifle against warm stove in a hunting cabin. Guess what - 'iron' sights melted, cause the barrel heated up. Yes, right he was careless, but ... sights melted....
Another rifle with interchangable barrels I know about is Sauer 202. In Europe it's available in 'Alaska' model - syntetic stock and teflon coating on metal parts. I never handled it, but heard it's very good. On Sigarms web site they show only supreme model with wooden stock - don't know if they sell 'Alaska'.
