Of the rifles I own, sixty percent are based on some form of Mauser.
The one Winchester I have is a very nice rifle, but it is not built with the same quality of any of the others I own, and it was posted in the EE some weeks ago. The only other American built rifle I own is a Dakota 76 Classic and it is amazing. It is also a very expensive custom, that I got an increadible deal on. In no way is it fair to compare a Dakota to an out of the box Remington, Savage, or Winchester.
I've sold a few Mausers as well. All were fine old guns that I'd still have if I hadn't needed to sell them to help finance the Dakota 76. I sold Rembo two of his Sako's for that very reason. I did keep the best of them though, a beautiful Sako A-IV Laminated in .270 Winchester that remains my favorite shooter in the collection.
I'd say that regardless of whether its built in the United States, Europe, or elsewhere, one high quality firearm, in a favourite calibre, is definitely worth the price of three or four lesser rifles. If its a Mauser, then that's good too.
My never part with list includes the Dakota, but the remaining special items are all European. So my collection will probably pare down to three rifles when my kids are old enough to leave home. That wonderful 270 is promised to my oldest son, who also gets a CZ. His brother wants two BRNO's and a Sako. My daugher will get her pick when she's ready. I'm keeping the Dakota, and a Sauer, I may one day replace another Sako with something like a Blaser.
