I think this Ruger 375 Guide rifle is very interesting and may be a real winner. I don't think there is a Ruger 375RCM, it's the Ruger 375 I believe as they don't make an RCM in 375 . As far as cartridges go, gun shops typically carry familiar ammunition - hunting ammunition and the 375 H&H is like 30-06, I've never seen a store without those 2. So from a hunting perspective, a 375 H&H is almost an essential to have for biggest game and I'd suspect in those areas, they are never without that ammunition and in a pinch that is really important. Those Sako's have got a pretty good extraction system on them, I'm kinda interested to adding one to the collection, plus 1 of those Ruger's too. Someday when we look back your family will have a nice collection to divi up!
Happy New Year gentlemen, let's be safe in 2014.
